Shortcuts active in the Fractal Observatory view:

3 SHORTCUTS Fractal Observatory Shortcuts
Key Action Category Description
O Cycle Visualizer View Fractal Cycles Cosmos → Earth Observatory → Fractal Observatory. The mode button in the upper-left corner shows a small Mandelbrot while you are here.
M Minibrot Discovery Fractal Summons the Fractal Observatory's visitor: a slow landing on a tiny complete copy of the Mandelbrot set, with a callout naming the island. One at a time; the Minibrot button in the Control Panel toolbar does the same.
F Next Fractal Family Fractal Steps to the next of the seven fractal families, always in the same order (Mandelbrot, Julia, Burning Ship, Tricorn, Phoenix, Multibrot, Newton basins), so seven presses visit every one. A small label at the top of the screen names the family, for example BURNING SHIP; Zen Mode hides it. The Family button in the Control Panel toolbar does the same.
T Orbit-Trap Style Fractal Steps the scene on screen through the orbit-trap styles: none → Stalks → Rings → Petals → none, so you can compare one view under each. The label names the style, for example JULIA SET · STALKS. Newton basins have no trap styles. The Trap button in the Control Panel toolbar does the same.
R New Expedition Fractal Dissolves into a newly rolled scene: fractal, location, framing and colour harmony. Each of the seven families is equally likely, and R never lands on a minibrot (press M for that).

Space Invaders & Square Destruction Engine

Press I, double-tap the top of the screen on touch devices, or wait for an automatic assault wave to spawn an authentic 8-bit retro Space Invader. Invaders feature 16 procedural arcade archetypes (Squid, Crab, Octopus, Beetle, Mantis, UFO, Ghost, Cyclops, Sentinel, Wasp, Drone, Titan, Viper, Phantom, Stalker, Overlord) with guaranteed vivid neon glowing eyes, 2-frame walking animations, pixel trail emissions, and intelligent combat pathfinding:

  • Hunter Mode: In addition to ambient flybys, triggering Hunter Mode via H or Shift+I dispatches an aggressive Hunter Invader (or immediately upgrades an active Invader into a Hunter) that actively seeks out and disintegrates lingering unplayed album squares, historic spacecraft, and floating astronauts with high-speed lateral strafe-firing runs, stationary hover barrages, and 8-bit arcade explosion debris particles.
  • Periodic "Seek & Destroy" Capacity Engine: Once the maximum square limit is reached (or when the Max Squares slider is lowered), cleanup assault waves are launched by either a single Space Invader (60% chance) or a coordinated 4-invader squadron (40% chance). Flying in tight synchronized formation with leadership handovers, Invaders scan member columns for unplayed squares, sidestep directly over targets, and obliterate surplus squares with downward laser blasts and contact explosions into pixel debris.
  • Obstacle Evasion AI: When descending across the canvas, Invaders detect active album squares in their path and execute orthogonal sidestepping maneuvers to bypass obstacles without colliding.
  • Retro Laser Cannons: When trapped between obstacles or actively clearing surplus squares, Invaders fire rapid downward laser bolts with cannon recoil and screen-wide sparkle bursts.
  • Zen Mode Protection: Floating squares are 100% immune from Space Invader targeting and laser destruction while in Zen Mode Z.

Modular Spacecraft Builder & Pilot Mode

Design, build, and pilot your own custom spacecraft directly inside the Cosmic Visualizer. Access the builder workshop anytime by pressing L, clicking Create Your Spacecraft in the Control Panel, or clicking on any drifting astronaut.

  • 8,000 Modular Combinations & Fleet Persistence: Choose from 20 Top nose modules, 20 Mid command modules (including the animated Mid Part 9 Reactor Core with transparent observation containment window and rotating magnetic plasma rings), and 20 Bottom propulsion engines with live 3D-perspective rotating previews, performance attribute ratings (Thrust, Agility, Hull, Warp), and automatic localStorage fleet saving.
  • Arrow-Exclusive Keyboard Workshop Navigation: Navigate module rows and the Launch button using ↑ / ↓; cycle previous/next part components with ← / →; jump directly to any section using number shortcuts 1 (Top), 2 (Mid), 3 (Bottom); press Enter or Space to launch; and press Escape to dismiss the modal.
  • 360° Rotational Flight Steering: Steer your custom craft across deep space with authentic rotational physics: ← / → rotate heading angle with rotational inertia, ↑ fires forward main propulsion thrusters, ↓ engages active retro-thruster braking, and the on-screen analog touch joystick flies the same way, relative to the craft: push left/right to turn, up to thrust forward, down to brake.
  • Mid-Flight Spacecraft Collisions & Elastic Deflections: Physical collision engine detects impacts between your craft and all 9 historic fleet vessels, Flying Saucers, and Space Invaders. Computes collision normal vectors, applies elastic bounce impulses (5.8px cruise / 8.5px hyperdrive), deflects target fleet craft with velocity offsets, and applies angular heading jolts with 240ms debounce protection.
  • Retro 8-Bit Pixel Disintegration & Sub-Bass Collision Audio: Colliding with Space Invaders detonates them into 20–35 chunky 8-bit square pixel debris particles, while UFO collisions release brilliant 4-point diamond glint stardust bursts. All physical impacts trigger a synthesized sub-bass crash boom (95Hz➔28Hz sweep) with metallic plate resonance and 2.6s reverb tail.
  • Hyperdrive Boost Afterburners: Press Space or tap the on-screen Hyperdrive button to engage lightspeed boost with multi-stage warp star-streaks, ion particle exhaust trails, screen vibration, and low-end dual-tone audio roar (65Hz/220Hz + 7.5Hz LFO flutter).
  • Astronaut Search & Rescue Gameplay: Intercept drifting astronauts across deep space to trigger ascending pentatonic chime arpeggios, stardust particle bursts, and increment your live rescue counter in the Pilot HUD. Rescued astronauts receive full immunity from UFOs and Invaders.
  • Continuous Replenishment & 10-Minute Idle Auto-Exit: If an active astronaut drifts off-screen or is abducted, the visualizer automatically queues the next astronaut on a 25–55s cadence. If 10 minutes elapse without a rescue, Pilot Mode automatically executes a graceful warp exit to restore ambient playback.
  • Procedural Audio Suite & Quindar Tones: Real-time synthesized continuous thruster rumble, dual-frequency hyperdrive sub-bass roar, builder workshop audio stings, and authentic 2.5kHz Apollo Quindar radio tones preceding every launch.

Astrophotography & Visualizer Physics

The visualizer simulates genuine astronomical mechanics using custom canvas rendering pipelines, offscreen sprite texture caches, and mathematical models:

Galaxies
Galactic Structure & Companion Dwarfs

Grand design logarithmic spiral arms, central stellar bars, ring galaxies, Active Galactic Nuclei (AGN), and orbiting Magellanic satellite dwarf companions with Keplerian orbital rotation lag and tidal trail shearing.

Constellations
11 Astronomical Sky Presets

Astronomically accurate star maps for Orion, Ursa Major (Big Dipper), Ursa Minor (Little Dipper), Cassiopeia, Cygnus, Leo, Scorpius, Taurus, Pegasus, Canis Major, and Triangulum with interactive star linking, 1st-magnitude hero star diffraction spikes, and proximity hierarchy damping.

Optics
Stellar Optics & Micro-Lensing

Stellar cores render Airy disk wave rings, Hubble 4-point diffraction spikes, optical ghost reflection halos, RGB chromatic aberration, interstellar extinction dust reddening, and Einstein gravitational micro-lensing arcs around dense galactic cores.

Shocks
Filaments & Protostellar Jets

Braided Veil Nebula supernova remnant ionization ribbons and Herbig-Haro protostellar bipolar plasma jets across 6 authentic astronomical morphologies (collimated needle, cocoon pillar, bubble hourglass, swept arc, butterfly cavern, turbulent clumpy) with orbital molecular cloud tethering.

Kinetics
Pulsar Beacons & Relativistic Kinetics P

Spinning relativistic neutron stars with dual synchrotron radiation lighthouse beams, 3D sky inclination tilt, and sin6(θ) rotational strobe power curves. Spawns spontaneously or on demand via P.

Dynamics
Comets, Meteors & Celestial Dynamics C M

Fast-moving comets with dual-tail rendering (white-hot nucleus, neutral dust tail, and curved Type-I ionized gas streamer), radiant meteor showers with multi-angle atmospheric entry vectors, and kinetic flick gestures.

Deep Space Astrophysics & Particle Simulation Subsystems

Beyond static backgrounds, the visualizer runs continuous mathematical solvers that govern starfield kinetics, relativistic optics, and hydrodynamic shock propagation:

  • 6 Herbig-Haro Protostellar Jet Archetypes: Protostellar outflows are modeled on real astrophysical classifications: Collimated Needle (ultra-narrow Mach shock), Cocoon Pillar (dense Bok Globule dust cocoon with extinction lanes), Bubble Hourglass (rounded balloon cavities with concentric ripples), Bent Swept Arc (crosswind-sheared C-curved bow shock), Butterfly Cavern (asymmetric biconical lobes inspired by HH 46/47), and Turbulent Clumpy (chaotic starburst gas puffs with corkscrewing streamers). Jets dynamically tether to and orbit their parent host dust nebula.
  • Interstellar Dust Extinction & Stellar Reddening: Background stars traversing dense cosmic dust lanes undergo real-time Rayleigh scattering, wavelength-dependent absorption, and luminosity extinction, naturally shifting stellar color spectrums toward deep amber and infrared tones.
  • Gravitational Singularities & Acoustic Shockwaves (Pointer Hold): Pressing and holding anywhere on the cosmic background activates an Einstein-Rosen gravitational singularity. Nearby stars, gas particles, and historic spacecraft are gravitationally accelerated toward the singularity with optical lensing distortion. Releasing the hold unleashes a supersonic acoustic shockwave burst that disperses surrounding matter outward.
  • Comets, Radiant Meteor Showers & CCD Cosmic Rays: Fast-moving comets calculate dual-tail dynamics (a white-hot nucleus with both a neutral dust tail and a curved Type-I ionized gas streamer). Meteor showers generate randomized radiants across multiple atmospheric entry vectors. Ultra-rare CCD cosmic ray sensor strikes occasionally deposit sharp ionization needle tracks across the viewport, simulating genuine deep-space telescope exposures.

Performance Engine, Adaptive LOD & Diagnostic Telemetry

1kx is engineered for sustained 60 FPS performance across mobile phones, laptops, and 4K displays through an adaptive Level-of-Detail (LOD) engine and zero-allocation object pooling.

Quality is a single four-step ladder. Full Quality and Eco Mode are simply the names of steps on it — not separate switches. The engine walks up and down the ladder on its own, and you can pin any step manually.

Quality Tier Entered when… Rendering Adjustments & Optimizations
Tier 0: Full Quality Default · frames comfortably inside budget All 9 full-screen background shaders active, full starfield density, up to 12 gas and 12 dark nebula clouds, high-resolution micro-galaxy swarms, and maximum bloom effects.
Tier 1: Balanced Average frame > 20.8 ms
(≈1 frame in 4 dropped)
Window transparency and backdrop blur removed for opaque panels; nebula clouds capped to 8 gas / 8 dark; sonic palette and FFT sampling throttled; cached morphology blits and proportional particle limits.
Tier 2: Eco Mode Average frame > 25 ms
(≈half the frames dropped)
Flattens heavy CSS background gradients into a single composite fill, clamps canvas DPR to 1.0×, caps clouds to 6 gas / 5 dark, and freezes the background entirely while a remix is playing to hand the whole CPU budget to audio.
Tier 3: Minimal Average frame > 33.3 ms
(a dropped frame for every drawn one)
Everything above, plus canvas rendered at 0.85× and re-scaled, clouds capped to 4 gas / 3 dark, and remix meter polling dropped to 5 Hz.

Why milliseconds rather than FPS? On a 60 Hz display frame times quantise to 16.7 / 33.3 / 50 ms, so an "average FPS" figure hides what is actually happening. The thresholds above are chosen as frame-drop ratios — 25 %, 50 %, 100 % — which is the thing you can actually perceive.

Coming back up. Recovery thresholds are deliberately stricter than the ones that triggered the drop (17.5 / 19.5 / 23 ms), and a tier must hold for several seconds before the engine climbs. That hysteresis is what stops the ladder oscillating on a machine sitting right at a boundary. Leaving Eco Mode also uses a progressively longer cooldown, so a device that keeps struggling is not repeatedly promoted.

Manual control. The performance button cycles Auto → Tier 0 → Tier 1 → Tier 2 → Tier 3 and back to Auto. Picking a tier pins it; Auto hands control back to the ladder. Press D to watch the current tier live in the Telemetry HUD.

One thing deliberately not tier-gated: the 12× retro pixelation that engages during a remix. It applies at every tier including Tier 0, because it is an aesthetic signal that you are in remix mode — not only a performance measure. The ladder changes whether that pixelated background animates, not how large the pixels are.

Live Telemetry HUD D

Press D or click the bug icon in the Control Panel to open the collapsible Telemetry HUD. Inspect live metrics for:

  • Engine & Graphics: FPS, Frame Time (ms), LOD Tier, Canvas DPR, and Adaptive Subsampling.
  • Cosmic Objects: Live counts for Stars, Galaxies, Mini-Clusters, Filaments, Pulsars, Comets, Meteors, Spacecraft, and Invaders.
  • Audio Channels: Real-time FFT levels across Sub, Low-Mid, High-Mid, and Treble registers.
  • Preloader & History: Audio buffer status, track cache hit rates, recent play logs, and DOM class state transitions.

Earth Observatory (Orbital Reconnaissance)

Earth Observatory is a high-altitude orbital remote sensing visualizer mode running on procedural multi-octave fractal elevation shaders and satellite optics. Floating album squares drift over living continental landforms, meander scrolls, coastal waters, and glowing nocturnal city corridors while music plays. Press O at any time or click the mode button in the upper header to cycle between deep-space Cosmos view, Earth Observatory view, and the Fractal Observatory.

Comparison
Cosmos vs. Earth Observatory

Earth Observatory shares its underlying visualizer foundation with Cosmos view: floating album squares glide with low-drag inertia, Zen Mode Z clears all UI overlays, Retro Pixelation . cycles 5 arcade downsampling tiers, Remix Console V runs the 4-stem mixer and Autopilot Mix Shift+D, Visualizer Snapshot Tool K exports clean high-res captures, and Redraw R generates a fresh procedural seed. The key difference is the landscape and its tools: instead of deep-space astrophotography, starfields, nebulae, and historical spacecraft, you explore high-resolution procedural Earth terrain with multi-spectral satellite sensor bands, an orbital reconnaissance telemetry HUD, fractal zoom adjustments, and flybys from the SimPlane aircraft fleet.

Sensors
5 Spectral Sensor Bands 1–5 + Shuffle 0

Choose a band with hotkeys 1–5, the bottom HUD sensor bar, or the Control Panel dropdown: SimPlane 1 (SimPlane's actual 3D world from above, at a random location, sometimes over the airport), Thermal Night 2 (urban radiance corridors and city lights), LiDAR DEM 3 (topographic elevation and meander scrolls), CIR Infrared 4 (false-color vegetation biomass health), Agriculture & Cityscape 5 (center-pivot irrigation mosaics and procedural city fabric), and Shuffle 0 (smooth ambient auto-cycling every ~90 seconds). Redraw R on the SimPlane band flies to a new location.

Telemetry
Recon Telemetry HUD H

Press H or click the Recon HUD button in the Control Panel to toggle the orbital reconnaissance HUD. Displays the view's coordinates and altitude (on the SimPlane band, SimPlane's own x/z position and camera height, shown as dashes while a sector is still being acquired; on the other bands, latitude/longitude and the 694.2 KM orbital altitude), optical corner reticles, and quick-selector band badges. Stays fully toggleable during Zen Mode.

Aviation
SimPlane Aircraft Flybys P

In Cosmos view, P spawns a pulsar and numbers 1–9 launch historical spacecraft. In Earth Observatory, pressing P or clicking Plane Flyby launches a procedural aircraft from SimPlane's fleet across the satellite frame—complete with civilian or military liveries, proportional wingspans, contrails, and a cabin chime. Click any flyby aircraft to view its specifications and launch directly into SimPlane to pilot it.

Screen Capture
Visualizer Snapshot Tool K

Captures clean, high-resolution satellite reconnaissance imagery by pressing K or clicking the camera toolbar icon in the Control Panel. Automatically strips all DOM elements, floating music cards, reticles, and open panels for a fraction of a second to render a pristine canvas composite with optional algorithmic telemetry watermark, clipboard copy, and PNG download.

Parameters
Control Panel

When Earth Observatory is active, the Control Panel X adapts dynamically: celestial triggers are replaced with Earth buttons (Sensor Band cycle, Recon HUD toggle, Plane Flyby), and the Adjust Parameters drawer E displays Altitude (formerly Fractal Zoom; 1.7–12.0 km, default 5.0 km) for zooming the view, alongside the Sensor Band dropdown.

The 5 Multi-Spectral Sensor Bands

Earth Observatory visualizes planetary terrain through five specialized imaging spectra, accessible via numeric hotkeys 1–5, the bottom HUD sensor bar, or the Control Panel:

  • Band 1: LiDAR DEM (Digital Elevation Model) 1: Topographic hypsometric heightmap rendering elevation gradients from deep oceanic trenches through coastal lowlands to highland plateaus. Emphasizes geological geomorphology, alluvial plains, braided riverbeds, and meander scroll cutoffs.
  • Band 2: CIR (Color Infrared) Vegetation 2: False-color near-infrared (NIR) composite modeled on Landsat and Sentinel-2 agricultural bands. Reflective plant chlorophyll and dense forest canopies glow in vibrant neon magenta and pink, while water bodies absorb infrared radiation to appear in stark dark navy tones.
  • Band 3: Thermal Night (Urban Radiance Corridor) 3: Nocturnal low-light sensor capturing nighttime metropolitan footprints. High-density urban cores, industrial ports, and arterial highway ribbons shine with warm incandescent and golden radiance against cold landmasses and oceanic coastlines.
  • Band 4: Agriculture & Cityscape (Pivot Irrigation) 4: High-resolution mosaic combining circular center-pivot irrigation crops, rectilinear farm boundaries, and procedural sim city fabrics complete with street grids, building blocks, and district layouts.
  • Band 5: Shuffle Auto-Cycle (Ambient Tour) 5: Hands-free ambient demonstration mode. When active, Earth Observatory smoothly cross-fades between randomized sensor bands and geographic coordinates every ~90 seconds, accompanied by gentle coordinate panning.

SimPlane Aircraft Fleet Integration P

Instead of deep-space historical satellites, Earth Observatory features procedural aircraft flybys powered by SimPlane's shared aircraft fleet registry:

  • Spawning Aircraft Flybys: Press P or click the Plane Flyby icon in the Control Panel to dispatch an aircraft across the satellite frame. Aircraft cruise diagonally across the viewport with realistic cruising velocities and a two-tone cabin chime.
  • Fleet Variety & Liveries: Flybys dynamically select from civilian airliners, supersonic jets, business transports, and military aircraft across 11 authentic hull swatches (white, silver-grey, navy, sky blue, gunmetal, and olive drab), with proportional wingspan geometries and trailing engine contrails.
  • Interactive Telemetry & Flight Simulator Link: Clicking any active flyby aircraft opens an on-screen telemetry badge displaying its model name, operational role, wingspan, and passenger capacity, along with a direct Fly in SimPlane link to pilot that exact aircraft in the full 3D flight simulator.

Recon Telemetry HUD & Optical Overlays H

Press H or click the Recon HUD button in the Control Panel toolbar to display the tactical reconnaissance overlay:

  • Orbital Telemetry Readout: Top-left HUD card showing where the view is and how high: on the SimPlane band, SimPlane's x/z position in kilometres and the camera's altitude above the ground (dashes until the sector's frame is on screen); on the other bands, latitude/longitude and the orbital altitude (694.2 KM).
  • Corner Optical Reticles: High-precision framing brackets anchoring the four corners of the nadir optical camera sensor.
  • Bottom Sensor Selector Bar: Pinned to the bottom-left corner, providing instant one-click switching between sensor badges 1 DEM, 2 CIR, 3 NIGHT, 4 AGRI, and 5 Shuffle with active state highlights.
  • Zen Mode Compatibility: The Recon HUD is designed to remain toggleable via H even while Zen Mode Z is active, allowing clean tactical monitoring without unhiding music player controls.

Fractal Observatory (Abstract Generative Art)

The Fractal Observatory is the third visualizer view: pure abstract generative art drawn live from seven fractal families, from the Mandelbrot and Julia sets to the Burning Ship and Newton basins. It evolves slowly and ambiently while the music plays. Press O to cycle Cosmos → Earth Observatory → Fractal Observatory, or click the mode button in the upper-left corner, which shows a small Mandelbrot silhouette while you are here.

Expeditions
Drift & Dissolve

Each scene is an expedition: a random fractal, location, starting depth, framing and colour harmony. A scene can open anywhere from a view of the whole figure to deep in its filigree (up to a few hundred times magnified on the Mandelbrot-style sets; shallower on Julia, Phoenix and Newton, whose shapes morph as you watch). It plays out slowly (a gentle zoom dive into the filigree, drift, rotation, and on Julia, Phoenix and Newton scenes a slow reshaping) and then dissolves into a newly rolled one. Compositions are often cropped and off-centre on purpose. Press R (Redraw) to jump straight to a new expedition.

Families
Seven Fractal Families

Apart from minibrot landings, every expedition draws one of seven equally likely families: the classic Mandelbrot and Julia sets; the Burning Ship, diving along its antenna of little ships and spires; the three-cornered Tricorn; the Phoenix, a Julia set with memory; a Multibrot with three to six-fold symmetry; or Newton basins, where each of the scene's three colours is one root and the fractal lives on the borders between them. The first scene of a visit is always Mandelbrot or Julia, and R shuffles fairly among all seven. A small label at the top of the screen names the current family (hidden in Zen Mode), and F or the Family toolbar button steps through all seven in order. The family's name is also recorded in the snapshot watermark.

Styles
Orbit Traps

About one scene in three also wears an orbit-trap style, which colours each point by how close its path through the fractal passes to a hidden shape. Stalks (a cross) draws fine rays and filaments, Rings (a circle) sweeping arcs, and Petals (a single point) nested eyes and rosettes, all woven over the usual colour bands in a second colour from the scene's palette. Press T to step through the styles on the current scene.

Visitors
Minibrot Discoveries

Instead of spacecraft or aircraft, the Fractal Observatory's visitors are discoveries. Every so often an expedition finds a minibrot, a tiny complete copy of the Mandelbrot set hidden deep inside it, and slowly lands on it, with a small callout naming the island, its period and the magnification. Landings come up on their own in about one expedition in four; to summon one, press M or click the Minibrot button in the Control Panel toolbar.

Colour
Harmonies & Psychedelia

Every expedition rolls one of 16 three-colour harmonies (Twilight, Hearth, Storm, Lagoon, Aurora, Nebula and more). With Psychedelia low you see only that harmony; turning it up blends in the full rainbow palette and faster colour cycling. The harmony's name is recorded in the snapshot watermark.

Music
Subtle Breathing

The music influences the art only gently: bass nudges the colours and the glow inside the set, loudness slightly quickens the evolution, and high-frequency transients add a faint shimmer along the edges. Nothing ever jumps, and the view looks nearly the same with the music stopped.

Shared Visualizer Tools

Like Earth Observatory, the Fractal Observatory keeps the visualizer's common foundation: floating album squares, Zen Mode Z, Retro Pixelation ., the Remix Console V, the Visualizer Snapshot Tool K (captures are tagged 1kx-fractal-… and watermarked with the fractal family, the complex-plane location and the magnification), and Redraw R. Its own controls live in the Control Panel's parameter drawer E, described below.

Fractal Parameters

In the Fractal Observatory, the parameter drawer E replaces the cosmic gas and dust sliders with five fractal controls, remembered between visits:

  • Evolution Speed (1–10, default 5): how fast everything moves, including the zoom dive, drift, rotation, the reshaping of Julia, Phoenix and Newton scenes, and colour flow.
  • Fractal Zoom (0.3×–10×, default 1.0×): your own magnification on top of the scene's drift.
  • Psychedelia (0–100, default 20): at 0 you see only the scene's three-colour harmony. Turning it up blends in the full rainbow palette, speeds up the colour cycling and pushes saturation toward neon.
  • Detail (60–420 iterations, default 240): edge filigree against GPU cost. It is scaled down automatically on lower performance tiers.
  • Expedition (1–20 minutes, default 8): how long each scene lasts before it dissolves into a new one.

Reset to Default restores all five.

Smooth Fine Detail

Fractal edges hold detail far finer than a pixel, which normally shimmers or "crawls" as the view moves. The Fractal Observatory softens colour bands that are too fine to display, and averages several slightly offset samples of every pixel over successive frames. Fine filigree stays calm and crisp while the art drifts.

Audio Engine & Harmonic Sonic Palette

1kx incorporates a custom Web Audio API processing architecture with real-time frequency distribution mapping and dynamic harmonic color synthesis:

Architecture
Dual-Channel Gapless Machine

Dual independent HTML5 audio channel engines with sub-millisecond ping-pong crossfading, pre-buffering, and a continuous background silent audio carrier that prevents in-car Chromium media overlays (such as Tesla) from interrupting continuous playback.

4-Band FFT
Frequency Register Analysis

Continuously separates acoustic energy into Sub (bass drums), Low-Mid (basslines/rhythm), High-Mid (vocals/keys), and Treble (cymbals/air) with balanced gain calibration.

Normalizer
Self-Normalizing Dynamic Contrast

Continuously tracks a running acoustic energy baseline to isolate predominant frequencies, preventing spectral teal bias and ensuring vivid responsive visual dynamics across both quiet acoustic tracks and high-energy anthems.

Atmosphere
Harmonic Aurora & Warmth Flux

Synthesizes deep-space aurora hues that gently shift across sapphire, emerald, and solar gold, modulating transient cosmic warmth and chromatic temperature during heavy drum beats and chorus crescendos.

Metadata
Per-Album Cover Art & MediaSession Artwork

Player thumbnails resolve a static cover.jpg/cover.png file from each track's own album directory — one shared image per release, extracted once rather than parsed from each mp3/m4a's own tags. A separate band-logo array covers MediaSession lock-screen and dashboard artwork for Tesla Chromium and Linux MPRIS displays.

Soundscapes
Ionospheric Signals Synthesizer

Real-time procedural Web Audio soundscape engine synthesizing Eckersley whistler dispersion sweeps, Apollo Quindar radio beeps, lightning sferics, chime motifs, and hauntological reverse-grain song ghost fragments sampled from the 1kx library.

Procedural Soundscapes, VLF Ionospheric Signals & Audio DSP Architecture

Beyond musical streaming, 1kx features a real-time procedural Web Audio sound synthesis engine that models atmospheric radio propagation, space-age telemetry, and hauntological audio effects:

  • Eckersley Plasma Dispersion & VLF Whistlers: Synthesizes Very Low Frequency (VLF) magnetospheric whistler chirps using the astrophysical Eckersley dispersion relation (\(t \propto D / \sqrt{f}\)), where higher radio frequencies travel faster along geomagnetic plasma ducts. Uses parallel detuned oscillators (sine carrier + triangle harmonic warmth) to synthesize 5 distinct trajectories: Classic Downward Dispersion, Upward Rising Hook / Tweek, Nose Whistler (with parabolic inflection frequency \(f_{\text{nose}}\)), Multi-Hop Conjugate Echoes, and Dawn Chorus Micro-Chirps.
  • VLF Lightning Sferics, Shortwave Heterodynes & Poisson Static: Simulates global atmospheric lightning strike radio pulses traveling through the Earth-ionosphere waveguide, generating Poisson-distributed burst crackles, bandpass filtered white noise transients, and multi-frequency heterodyne beating.
  • NASA Apollo Quindar Tones: Procedurally generates historic Apollo Push-To-Talk (PTT) radio signaling beeps (2525 Hz intro beep and 2475 Hz outro release beep) with authentic atmospheric carrier hiss and squelch gating.
  • Hauntological 1kx Song Ghost Fragments (15 DSP Modes): Samples real audio buffers from the 1kx music library and transforms them through 15 real-time DSP modes: Granular Cloud / Shimmer, Reverse Tape Grain, Deep Drone Sub-Harmonics, Telemetry Vocoder, Gramophone 78 RPM Filter, Comb Filter Phase Flange, Doppler Flyby Pitch Shift, Bitcrushed Lo-Fi Downsampling, Stutter Slicing, and Ionospheric Multipath Fading.
  • When & How Audio Effects Trigger:
    • Ambient Idle Scheduler (No Song Playing): When playback is idle, a stochastic scheduler periodically triggers a subtle radio event every 12–24 seconds (38% 1kx Ghost Fragments, 22% VLF Sferics, 15% Apollo Quindar, 17% Dawn Chorus Tweeks, 5% Eckersley Whistlers, and ~3% Ethereal Melodic Motifs strictly gated to a 10-minute cooldown).
    • Auto-Sleep During Music: The ambient idle scheduler automatically pauses while songs are playing to keep the listening experience pristine.
    • On-Demand Manual Trigger ` / ~: Immediately composes a full ~10-second multi-stage atmospheric radio journey with synchronized CRT scanline interference.
    • Master Slider Control: The Ionospheric Signals slider in the Parameter Drawer E modulates volume (0–100%), with 0% completely muting and bypassing all background synthesis.
  • Tactile Vinyl Turntablism & Kinetic Acoustics: Dragging floating album squares generates live vinyl slip hisses and baby scratch chirps via zero-allocation white noise buffer pooling, while viewport boundary bounces trigger needle pop acoustics.

Remix Console & Studio FX Desk

The 1kx Remix Console provides a hardware-inspired live mixing desk, multi-bus FX matrix, and analog drum computer for transforming songs in real time with studio precision.

Console Mixer
4-Stem Channel Strips

Splits tracks into Drums, Bass, Vocals, and Other. Each strip features vertical volume sliders, stereo LED peak meters, hardware Mute M / Solo S toggles, and 360° rotary pan dials.

Routing & FX
Pre/Post FX Sends & Return Processors

Independent 4-band FX send matrices per channel route dry (PRE fader) or gain-scaled (POST fader) taps into four parallel studio return processors: 80s BBD chorus & ducking pump, vintage telephone bitcrusher with tape flutter, chopped vaporwave reverb, and harmonic ambient shimmer with dedicated rotary stereo panners and return faders.

Generative DJ
Autopilot Mix Shift+D

Autonomous generative live mixing subsystem executing phrase-locked transitions across 4, 8, and 16-bar intervals. Features motorized fader animations, real-time telemetry badges, dynamic drops, stem ducking, and 100% non-destructive user baseline restoration when toggled off.

Drum Machine
1KX-808 Rhythm Composer BETA

8 synthesized Roland TR-808 drum voices: BD, SD, LT, HT, CL, CB, CLV, HH with 16-step sequencer grid, automated track tempo sync & beat mapping (beta: may not align correctly on all tracks), 1/2x halftime mode, dedicated rotary stereo pan, volume fader, continuous loop latch, and procedural dice randomizer.

Performance
Live Performance FX & Stutters

16 color-coded performance pads across Stutter Rolls and Ghost Anomalies/Beat Modifiers, featuring dedicated rotary stereo pan, master volume slider, pitch dive laser drops, accelerating risers, tape stops, dub cuts, and tempo-locked authentic acoustic "Ramen break" drum layers.

Recording
Offline MP3 Export & Art Capture

Direct offline LAME MP3 export combining live stem balances, FX processing, embedded WebGL visualizer screencap album art, and minute-precision timestamp metadata ([Title] (1kx Remix - YYYY-MM-DD HH:MM)).

Mixer Desk Operations & 4-Stem Channel Strips

The mixer desk provides multi-track tactile control over the balance, stereo placement, and acoustic isolation of each isolated stem:

Deck Transport Controls & Interactive Scrubber Space

The integrated deck transport provides direct playback control without leaving the remix console or losing mixer focus. Use the transport buttons to skip back |◀, play or pause ▶/❚❚ or Space, skip forward ▶|, engage continuous playback mode ∞, or close the active track ✕. The interactive scrubber bar lets you seek to any position in the song with elapsed time and remaining countdown timers (click the time display on the right to toggle between countdown and total duration). When playback is paused, meters sleep automatically to conserve CPU.

HD AI Stems vs. 4-Band DSP Crossover Indicator

Located in the mixer desk header, the stems indicator displays whether playback is driven by discrete 4-stem AI separation (HD AI STEMS) or real-time spectral crossover filtering (4-BAND DSP). Click the badge at any time during playback to toggle between stem modes on the fly.

Managing Levels, Balance & Stereo Pan

Each of the four AI-separated channel strips (Drums, Bass, Vocals, Other) features a vertical volume fader ranging from 0% to 150% gain (+3.5 dB boost) with integrated stereo LED peak meters. Use the 360° rotary pan knobs to position instruments anywhere in the stereo field from left to right (L100% to R100%).

Isolating Elements with Mute & Solo

Click M on any channel to instantly silence that stem, or click S to solo it. Soloing multiple channels lets you build custom sub-mixes—such as isolating an a cappella vocal over acoustic guitar, or stripping away everything except the rhythm section.

Configuring PRE vs. PST Routing Taps

Each stem FX send can be tapped either pre- or post-fader depending on your performance workflow:

  • POST (PST - Default): The effect send is tapped after the channel volume fader. Moving the channel fader down reduces both the dry instrument and its effect level proportionally.
  • PRE (Dry Tap): The effect send is tapped before the volume fader. Pulling the dry channel fader all the way to 0% leaves the 100% wet reverberation, delay tail, or chorus ringing out in the mix—ideal for dub-style vocal drops, transition risers, and ambient washes.

3-Band Musical Equalizers (Stems & FX Returns)

Every channel strip and Aux return channel features a dedicated 3-band parametric EQ:

  • HI (High Shelf, 8 kHz): Adjusts high frequencies above 8 kHz (-15 dB to +15 dB) to boost treble brightness or reduce harshness and sibilance.
  • MID (Peaking, 1.2 kHz): Adjusts midrange frequencies centered at 1.2 kHz (Q=1.0, -15 dB to +15 dB) to adjust vocal presence and instrument body.
  • LOW (Low Shelf, 100 Hz): Adjusts low frequencies below 100 Hz (-15 dB to +15 dB) to adjust bass weight or reduce low-end rumble. Double-click any knob to reset to 0 dB unity.

Studio Master Bus Channel Strip

Positioned at the far right of the console, the Master bus controls final sum output:

  • Master Limiter (LIMITER): Web Audio DynamicsCompressor peak limiter on the master bus, preventing digital clipping.
  • Master Fader (0–150%) & Stereo VU Meters: Vertical fader controlling output level with stereo L/R peak metering and numerical percentage readout (double-click for 100% unity).
  • Master DIM (-20 dB): Attenuates output by 20 dB (0.1x gain) without changing fader position.
  • Master Mute (M): Mutes master output.

Mastering Return Processors & Console Bypass B

The console includes dedicated rotary pan and return level faders for all four FX busses, allowing you to blend wet effects without cluttering individual channel strips. Click FX ACTIVE in the header or press B at any time to bypass all processing and A/B test your remix against the untouched original master.

Auxiliary Effects Matrix & Studio Processors

Expand the Aux Sends section on any channel strip to route that stem into four dedicated parallel studio effects. By default, the four slots load preset combinations: SYN, LOF, VAP, AMB, but clicking any slot's title or gear icon (⚙) opens the 15-effect studio DSP rack to select any processor. The slot buttons and send labels across all channel strips and the 1KX-808 dynamically update to reflect whichever effects you've configured in the four return slots:

15 DSP EFFECTS 15-Effect Studio DSP Rack & Acoustic Architecture
Effect / Preset Button Type DSP Character & Acoustic Architecture
Synth SYN Magic Preset 1980s bucket-brigade device (BBD) stereo chorus modulation with dynamic sidechain ducking pump.

Auto-Wah WAH Filter Dynamic envelope follower bandpass filter with sensitivity, base frequency, and Q resonance controls.
Rhythmic Gate GAT Modulation Tempo-synced tremolo and rhythmic stutter chop with customizable rate, gate depth, and smoothing shape.
Auto-Pan PAN Modulation Stereo field LFO auto-panner with adjustable panning rate, stereo width, and waveform shapes.

1KX-808 Rhythm Composer & Beat Mapping BETA

The 1KX-808 is a synthesized drum machine modeled after classic analog circuits, featuring an interactive 16-step sequencer grid, automated tempo synchronization, and dedicated Aux FX routing:

Beat Mapping & Alignment Notice: Automated beat mapping, bar anchor detection, and tempo synchronization are currently in active beta and may not work correctly or lock seamlessly on all songs in the catalog (especially tracks featuring free-tempo acoustic intros, rubato transitions, or live drumming variations). If the 1KX-808 drum machine or Amen breaks sound out of sync with a song, use the manual BEAT NUDGE buttons [ and ] or Shift+[ / ] to adjust the beat alignment, or click the downbeat offset readout to reset.

16-Step Sequencer & 8 Synthesized Voices 8 ∞

Click any pad on the 16-step grid to program rhythms across the 8 synthesized drum voices: BD Bass Drum, SD Snare, LT Low Tom, HT Hi Tom, CL Hand Clap, CB Cowbell, CLV Claves, and HH Closed Hi-Hat. Press 8 or click START to engage the drum machine—playback automatically synchronizes with the active song's tempo. Engage the continuous playback toggle ∞ to keep drum patterns running across song transitions, or leave it off to automatically stop the drum machine when changing tracks.

Rotary Stereo Pan & Master Output Gain

Located in the 1KX-808 header bar, use the 360° rotary PAN knob to position drum voices across the stereo field (L100% to R100%, double-click to center). The horizontal VOL fader controls drum machine output gain from 0% to 150% (double-click to reset to 100% unity).

Halftime Mode & Generative Dice Randomizer

Click 1/2x to shift the drum engine into halftime groove mode for hip-hop and trap rhythms. Click the Dice button to instantly generate fresh, musically coherent polyrhythmic drum patterns across all 8 voice lanes.

1KX-808 Aux FX Sends Matrix

Located above the 16-step pattern grid, the 808 FX send bar routes drum voices into any combination of the four studio effects returns:

  • Per-Slot Enable Buttons: Click any slot button SYN, LOF, VAP, or AMB to toggle effect routing for that slot. Labels dynamically update whenever you assign different processors to the return racks.
  • Rotary Send Dials: Adjust send level from 0% to 150% gain (double-click to reset to 100% unity).
  • PRE / PST Routing Taps: Toggle between PST (post-fader send, scales with 808 volume) and PRE (pre-fader send, allowing you to mute dry drum sounds while letting wet reverb/delay tails ring out).

Downbeat Grid Nudge & Beat Mapping System BETA

Located next to the BPM display in the 1KX-808 header, the BEAT NUDGE module lets you align drum patterns and break layers with the musical downbeat in real time:

  • Whole-Beat Shift [ / ] or ◀ BEAT / BEAT ▶: Shifts the downbeat earlier with Left [ or later with Right ] by ±1 whole beat for songs with pickup notes or unusual meter.
  • Fine 1/16th-Note Micro-Nudge Shift+[ / Shift+] or Shift+Click: Nudges downbeat timing by ±0.25 beat (one 1/16th note) earlier or later to lock in pocket timing for songs with swing or laid-back grooves.
  • Instant Reset: Click the numeric offset readout (e.g. +1.00, -0.25) to instantly reset the beat shift back to 0.00.

Live Performance Triggers & Beat Layers

The Remix Console features zero-latency performance pads for triggering buffer repeats, transitions, ghost anomalies, and acoustic break layers during playback. Use the header rotary PAN knob to position triggers across the stereo field (double-click to center) and the horizontal VOL slider to scale trigger volume from 0% to 150% (double-click for 100% unity). Pads can be clicked directly or triggered using keyboard hotkeys 1–8 and Shift+1–8:

13 PERFORMANCE TRIGGERS Live Performance Triggers & Beat Layers Table
Trigger Action Button / Pad Hotkeys Performance Behavior & Sound Character
Glitch Stutter Rolls 1/4 – 1/32 ROLL 1 – 4 Real-time synchronized buffer repeat slicing at 1/4, 1/8, 1/16, and 1/32 beat intervals. Instant momentary engagement for live build-ups and glitch edits.
Pitch Dive (Laser Drop) PITCH DIVE 5 Beat-synchronized varispeed downward frequency glide (1.45× → 0.32×) coupled with a resonant lowpass laser filter sweep (5000 Hz → 220 Hz, Q=4.5) and stem ducking.
Reverse Roll REV ROLL 6 Engages rapid syncopated 1/8-beat reverse roll chops across all active stem busses for dramatic transitional drops.

Ghost Ambient Swell GHOST SWELL Shift+2 Injects a lush 3.5–5.5s atmospheric ambient ghost swell (PaulStretch freeze drone, spectral shimmer, granular cloud, or ionospheric fade).
Ghost Reverse Swell GHOST REV Shift+3 Triggers a 2.0s time-reversed song ghost fragment swell that builds into the mix with spectral decay and reverse envelope.
Ghost Formant Vocoder GHOST VOC Shift+4 Morphs a 2.8s vocal formant vocoder filter, analog tape flange, cassette chew, or beacon orbit across preloaded song buffers.
Reverse Drop REV DROP Shift+5 Triggers an instantaneous reverse audio playback burst and build-up drop sweep with an automatic +6dB transient lift.
Dub Silence Cut DUB CUT Shift+6 Cuts master audio for exactly 1 measure of silence with cavernous dub reverb wash and tape echo reflections.
Ramen Break (1x Classic) RAMEN 1X Shift+7 Fires a 1-bar acoustic Amen Break fill (Gregory Coleman 1969 kick punch, dual-resonator snare, ghost notes, and funk swing). Use Alt+Shift+7 to latch continuously.
Ramen Break (2x Jungle) RAMEN 2X Shift+8 Triggers high-energy 2x tempo-doubled breakbeat fills with Alt+Shift+8 for continuous latch, passing through 3.6 kHz tape warmth and 90 Hz low-thump saturation filters.

Autopilot Mix & Live Performance Engine Shift+D

Autopilot Mix is an autonomous, non-destructive live performance subsystem built directly into the Remix Console. By tracking measure boundaries, tempo grid phase alignment, and track energy levels in real time, Autopilot orchestrates live hardware gestures, transitional drops, modular filter sweeps, and generative drum machine fills without ever destroying your custom mix:

3-Tier Musical Phrase Architecture

Autopilot evaluates musical structure across three hierarchical phrase intervals:

  • Major Phrase Boundaries (Every 16 Bars): Executes macro transitions—including Mono-to-Wide Explosive Drops, extended Vocal Dropouts (8, 16, or 32 bars), Pre-Fader Ambient / Vapor Washes (with rhythm cuts), musical Stem Mute Combinations (Beatless Drop, Rhythm Only, Drums Solo, Minimal Groove, A Cappella), and 808 Drum Swap Takeovers (muting acoustic drums and handing the beat exclusively over to the TR-808 for 4 or 8 bars).
  • Medium Phrase Boundaries (Every 8 Bars): Schedules synchronized 1/4–1/32 glitch stutter rolls, accelerating risers 7, laser pitch dives 5, turntable tape motor stops 8, Ramen break fills (1x classic or 2x jungle), atmospheric ghost swells Shift+2, reverse ghost swells Shift+3, stereo pan sweeps, and generative 808 pattern fills.
  • Cadence & Micro-Transitions (Every 4 Bars): Injects percussive ghost glitches Shift+1, vocoder formant sweeps Shift+4, quick 1/16th buffer rolls, dub cuts Shift+6, vocal dub delay throws, snare echo throws, 808 kick drops, cowbell pitch modulations, and master 808 volume accent swells—incorporating a 15% rest probability for natural musical breathing room.

Non-Destructive User Baseline Memory

Before triggering any gesture, Autopilot takes an instantaneous, complete snapshot of your manual settings—including all 4 stem volume faders, mute/solo states, rotary pan positions, Aux send routes (pre/post fader), send levels, return FX levels, master stereo width, and TR-808 drum machine parameters (voice volumes, pans, pitches, mutes, solos, pattern grid, and Aux FX sends). Any manual adjustment you make while Autopilot is running updates your baseline in real time. When gestures resolve or Autopilot is toggled OFF with Shift+D, all parameters smoothly glide or instantly snap back to your exact user baseline.

Motorized Hardware Visual Feedback & Gesture Highlighting

Controls and channel strips actively being automated by Autopilot highlight in real time as sliders and rotary dials smoothly adjust to execute live transitions. On lower-power mobile hardware or Performance Tier 2+, visual animations yield automatically to conserve battery and reserve 100% of DSP processing headroom for clean audio playback.

Signature Gesture Repertoire

Autopilot triggers a diverse collection of phrase-locked performance gestures:

  • Beat 4 Drop: Momentarily ducks drums, bass, and 808 on the 4th beat with faders physically gliding down to zero, slamming back to full power on the downbeat of Beat 1.
  • Mono-to-Wide Explosive Drop: Gradually narrows master stereo width down to near-mono (0.15) over 4 or 8 bars to build intense acoustic tension, then quickly swoops open into ultra-wide (1.45–1.50) on the drop before settling to baseline.
  • Dub Delay & Snare Echo Throws: Opens vocal or snare Aux sends hot (+20% to +25%) into delay/vapor right before a phrase turnaround, cleanly snapping closed on Beat 1 so echoes wash over the downbeat while the rhythm section remains dry and punchy.
  • Extreme Ambient & Vapor Washes: Mutes dry stems, ducks rhythm (drums, bass, 808), and engages healthy pre-fader Aux sends to ambient shimmer or vapor reverb, letting pure space reflections float across the soundstage before dropping the groove back in.
  • 808 Outro Conclude & Exit Engine: Automatically detects when a song is within 22 seconds of its conclusion and gracefully concludes the 808 drum machine using dynamic selection: a climactic parting fill before downbeat cutoff, sequential voice strip-down (cymbals/hats → snares/claps → kick), or a smooth 6–10 second master volume fade-out.

Zero-CPU Sleep Gating & Real-Time Action Badges

Autopilot automatically enters a zero-CPU sleep state when playback is paused, suspending all phrase timers and meter loops until audio resumes. An action indicator badge in the console header displays live gesture status (such as WIDE DROP, BEAT 4 DROP, DUB ECHO, 808 FILL, 808 OUTRO, or VOCAL DROPOUT) held for 2 seconds for easy reading.

Autopilot DJ Modes & Auto Resolution

Autopilot features six specialized performance personalities selectable from the DJ Mode dropdown in the console header:

  • AUTO (Intelligent Track Classification): Analyzes incoming song tempo (BPM) and metadata upon playback to automatically assign the ideal DJ style. High-tempo tracks (155+ BPM) trigger Jungle; mid-tempo hip-hop tracks (65–88 BPM) load the 808 engine; acoustic songs engage Pure mode; and uptempo or ambient tracks dynamically alternate between Space and Drift mixes.
  • SPACE (Cosmic Sweeps & Modulations): Deep space atmospheric mixing featuring sweeping phasers, flanger modulation rises, dub delay echoes, and explosive mono-to-wide drops. Automatically configures Phaser and Flanger into the active studio return slots.
  • JUNGLE (Drum & Bass / Amen Break Rave): High-energy breakbeat rave mixing featuring resonant DJ filter sweeps (low-pass and high-pass cutoffs), 303 acid squelch modulations, rapid 1/16th glitch rolls, and Amen break injections. Automatically assigns DJ Filter and Acid processors to return slots.
  • DRIFT (Minimal Vapor & Ambient Wash): Chill, downtempo atmospheric mixing with frequent rhythm dropouts (dropping drums, bass, or both for 2, 4, or 8 bars), lush pre-fader Vapor and Ambient reverb wash spillover on vocal and melodic stems, and wide stereo pan sweeps.
  • 808 (Generative Trap & Polyrhythmic Beats): Generative Euclidean TR-808 rhythm programming with dynamic 16-step pattern randomizations, rhythmic gating on bass and melodic stems, and tempo-synced ping-pong delay echoes. Automatically loads Rhythmic Gate and Delay into return slots.
  • PURE (Transparent Acoustic Balance): Transparent, organic mixing designed for acoustic and vocal tracks, focusing on gentle Beat 4 drops, sub-bass cutouts, subtle stereo widening, and natural stem level balancing without heavy synthetic modulation.

Intensity Controls & Dynamic Wildness Scaling

The rotary Intensity dial (0% to 100%, default 50%) in the Remix Console header scales gesture trigger probability, drop frequency, and modulation depth in real time. Low intensity settings (10%–30%) provide subtle, infrequent atmospheric washes and gentle dub delays for relaxed background listening. Balanced intensity (50%) delivers structured musical phrasing with periodic 8-bar breakdowns and 16-bar drops. High intensity (70%–100%) unleashes relentless live rave performance mixing with rapid glitch rolls, energetic 808 drum swap takeovers, and continuous filter sweeps. Click and drag the dial up/down to adjust, or double-click to reset instantly to 50%.

Real-Time Telemetry HUD Ticker

The integrated telemetry ticker in the console header provides immediate visual feedback on Autopilot operations: displaying the active DJ mode chip ([SPACE], [JUNGLE], [808]), live stem routing state chips (ALL 4 ACTIVE, VOC · OTH, DRM · BAS), real-time stem RMS audio energy percentages, and anticipatory phrase countdowns (such as ONLINE // SPACE MONITORING or DROP IN 4 BARS) so you always know what Autopilot is executing next.

Export, Performance Optimization & Session Memory

High-fidelity mix capture, intelligent GPU load-shedding, and persistent browser storage:

Exporting High-Fidelity MP3 Remixes

Click DOWNLOAD MP3 in the console header toolbar to export your mix. The offline multithreaded rendering engine captures a static snapshot of your mix faster than real time—baking stem faders, stereo pans, mute/solo balances, Aux send levels, return parameters, active effect slots, 1KX-808 patterns, and Ramen breaks (at 1x Classic or 2x Jungle speed) into a 256kbps MP3 with embedded WebGL visualizer screencap album artwork and timestamp metadata.

Background Pixelation & Song Indicator FX Toggle

To eliminate audio dropouts and protect GPU fill rate during heavy DSP mixing, 1kx automatically engages 12x retro pixelation whenever a remix is running. This remains active in the background even if you close the console. An interactive [ 🎛️ REMIX ✕ ] badge appears in the bottom-right song indicator—click this badge or press B to bypass the remix and instantly restore native starfield resolution.

Performance Tier Opaque Windows Optimization

On laptops and mobile devices, when Performance Tier 1 (Balanced), Tier 2 (Low Power), or Eco Mode is engaged, the visualizer automatically disables multi-pass Gaussian blur backdrop filters on all floating windows, modals, and HUDs. Windows render with high-contrast, opaque dark cyber styling (#070c12), directing 100% of GPU fill rate to silky-smooth 60 FPS starfield rendering.

Full Session Persistence: All stem volume faders, rotary stereo pans, Aux send levels, return parameters, Autopilot Mix state, 1KX-808 drum sequences, and 1KX-808 Aux FX sends automatically persist across sessions in localStorage.

Frequently Asked Questions

Why isn't audio playing automatically when the page loads?

Modern web browsers (Chrome, Safari, Firefox, Edge) enforce autoplay security policies that require an explicit user gesture (click or tap) before an AudioContext is allowed to output sound.

What are stems, and how does stem separation work?

Stems are the isolated multi-track component layers that make up a full song: Drums (kick, snare, hi-hats, percussive transients), Bass (sub-bass frequencies, basslines, 808 subs), Vocals (lead singing, speech, ad-libs, spoken word), and Other (melodic synths, guitars, pianos, ambience, acoustic instrumentation). In 1kx, tracks are split using high-definition AI neural network source separation (HD AI STEMS), allowing you to independently adjust volume balances, stereo panning, 3-band parametric EQ, and 4-slot Aux effect sends for each individual musical layer. If discrete stem audio files are still loading or unavailable, the system automatically uses real-time 4-band DSP spectral crossover filtering (4-BAND DSP) with zero startup latency.

Why isn't my remix playing or why is there silence when I adjust the console?

If you experience silence or playback issues within the Remix Console, check the following common causes:

  • Browser Autoplay Security Gate: Web browsers require an explicit click, tap, or Space keystroke before audio is permitted to play through the Web Audio context.
  • Muted Faders or Solo Traps: Check if channel M (Mute) buttons are active, channel faders are pulled to 0%, or a single silent channel is in S (Solo) mode. Also verify the Master Fader at the far right is raised and not set to MUTE or attenuated with DIM (-20 dB).
  • Pre-Roll Buffer Loading: When HD AI STEMS mode is active, all 4 stem audio streams must finish buffering. An animated hourglass and progress counter badge (BUFFERING STEMS (X/4)...) will indicate buffer status. If your network connection is delayed, 1kx automatically falls back to instant 4-band DSP crossover after a brief watchdog window so playback never freezes.
  • Console Master Bypass B: Press B or click FX ACTIVE in the header to toggle Master Clean Bypass. If a drastic filter cutoff or dry PRE fader send is silencing your mix, toggling bypass instantly routes the clean, original master recording directly to the speakers.
  • Reset Console to Defaults (RESET): If all else fails, click RESET in the console header (or double-click individual faders and knobs) to reset all faders, pans, sends, EQ bands, and drum patterns back to clean factory defaults.
What is the difference between HD AI Stems and 4-Band DSP Crossover?

HD AI STEMS uses discrete, studio-grade isolated audio streams pre-separated using deep learning neural networks. This delivers clean vocal a cappellas, punchy un-bleed drum tracks, and pristine instrument separation. 4-BAND DSP uses real-time Butterworth and Biquad spectral crossover filters on the master audio stream to split low, low-mid, high-mid, and treble registers directly on your CPU with zero network bandwidth and instantaneous startup. You can click the header stems badge at any time during playback to seamlessly switch between modes with zero audio dropouts.

How do I install 1kx on my phone or tablet home screen?

1kx is an installable Progressive Web App (PWA). In your mobile browser (Safari, Chrome, etc.), open the browser's Share or options menu and tap Add to Home Screen to run 1kx in standalone full-screen mode with touch gestures and offline asset caching.

Can I export and download my customized remix as an MP3?

Yes! Click the DOWNLOAD MP3 button in the Remix Console header. The offline multithreaded rendering engine compiles a static snapshot of your current mix into a high-fidelity 256kbps MP3 complete with embedded visualizer album artwork and minute-precise timestamp metadata. This snapshot captures all stem volume levels, rotary stereo pans, mute/solo balances, Aux send routing, and whichever effect is active at export time. If you have enabled the 1KX-808 drum machine or the Ramen Break layer, those full rhythmic tracks (synthesized at your selected 1x Classic or 2x Jungle speed) are synthesized and baked directly into the MP3 across the entire song duration. Note: Live performance pad triggers (1/4–1/32 glitch rolls, pitch dives, reverse drops) and dynamic real-time Autopilot Mix automations (such as periodic 32-bar FX morph sweeps) are live playback performance features and are not scheduled into the static offline MP3 render.

What is the difference between PRE and PST on the stem FX sends?

PST (Post-fader) taps audio after the volume fader, so lowering a stem also decreases its reverb/delay send level proportionally. PRE (Pre-fader) taps audio before the fader, allowing you to mute the dry stem while letting its 100% wet reverb echoes or delay feedback ring out continuously in the mix.

How does the Downbeat Grid Nudge work for the 1KX-808 drum machine?

If a song has a pickup measure or syncopated intro, use [ and ] or the ◀ BEAT and BEAT ▶ buttons to shift beat 1 by ±1 whole beat. For songs with subtle swing or laid-back pocket grooves, hold Shift while pressing [ / ] (or Shift-click the buttons) to nudge by a fine 1/16th note (0.25 beat). Click the numeric display at any time to instantly reset the offset back to 0.

Why did my visualizer switch to retro pixelation when I adjusted the mixer?

Real-time stem separation, multi-slot FX routing, and 8-voice drum synthesis place heavy demands on audio processing. To eliminate audio dropouts and save battery, 1kx automatically engages 12x retro pixelation mode during remix playback, slashing GPU fill-rate by 99.7%. This remains active even if you close the console. You can click the [ 🎛️ REMIX ✕ ] badge in the bottom-right song indicator or press B at any time to bypass the remix and instantly restore native resolution.

Does the Remix Console require an internet connection or cloud processing?

No cloud rendering is used. All stem mixing, DSP filtering, rotary panning, and MP3 encoding run 100% locally in your browser via the Web Audio API and multithreaded WebAssembly/JS encoders.

How does Autopilot Mix work, and will it overwrite my custom mixer settings?

Autopilot Mix Shift+D is an autonomous live remix engine that evaluates musical phrases across 4, 8, and 16-bar intervals to schedule live drops, motorized fader cuts, dub delay throws, and 808 rhythm fills in real time. It is completely non-destructive: before executing any gesture, Autopilot takes a full snapshot of your manual user baseline (stem levels, mutes, solos, pans, Aux sends, return levels, master stereo width, and 808 patterns). All parameters smoothly animate back to your baseline once the gesture concludes, and toggling Autopilot OFF instantly restores your untouched mix without changing your rack layout.

Why do sliders and dials glow and move on their own during Autopilot Mix?

Whenever Autopilot executes an automated gesture (such as a Beat 4 drop, mono-to-wide swell, snare dub delay throw, or pre-drop bass cut), the specific channel strips, knobs, or faders being modulated illuminate in real time and physically glide into position. This provides tactile visual feedback of every automated transition just like motorized faders on a physical studio console.

How do I rescue drifting astronauts in Pilot Mode?

Press L to launch your custom spacecraft into Pilot Flight Mode. Use ← / → to rotate and ↑ to thrust towards any drifting astronaut. Intersecting with their umbilical beacon completes the rescue, triggers a Quindar chime, and resets the idle flight timer.

How do I capture clean screenshots of the visualizer without UI menus?

Press K or click the Camera icon in the upper-left navigation bar. The snapshot engine automatically suppresses all floating HUDs, navigation bars, and open panels for a fraction of a second to capture a pristine WebGL/Canvas composite image with optional telemetry watermark.

What is Earth Observatory view, and how does it compare to Cosmos view?

Press O or click the mode button in the upper-left corner to cycle between deep-space Cosmos astrophotography, orbital Earth Observatory reconnaissance and the abstract Fractal Observatory (below). Earth Observatory renders procedural high-altitude satellite views across 5 multi-spectral sensor bands (LiDAR DEM, CIR Infrared, Thermal Night, Agriculture & Cityscape, and Shuffle auto-cycle). All core visualizer features—including Zen Mode Z, retro pixelation ., Remix Console V, screen capture K, and redraw R—operate identically in every view. Earth Observatory introduces orbital telemetry HUD readouts H, cycling satellite sensor bands 1–5, an Altitude slider (1.7–12 km), and the ability to launch procedural SimPlane aircraft flybys P rather than deep-space spacecraft.

What is the Fractal Observatory?

A third visualizer view of pure abstract art, generated live from seven fractal families (Mandelbrot, Julia, Burning Ship, Tricorn, Phoenix, Multibrot and Newton basins). Press O until the mode button shows the small Mandelbrot icon. Scenes ("expeditions") drift and slowly zoom, then dissolve into new ones; R jumps to a new one, F steps through the seven families in order (a small label names each; Zen Mode hides it), T steps through the orbit-trap styles (Stalks, Rings, Petals), and M summons a minibrot landing, the view's visitor. Its Control Panel sliders set the speed, zoom, colour intensity (Psychedelia), detail and scene length, and are remembered between visits. All the shared tools (Zen Mode Z, pixelation ., Remix Console V and snapshots K) work here too.

Are 'they' listening to me through the visualizer animations?

Yes, 'they' are always listening, but not through this application. All audio analysis is performed purely on the client side inside your web browser via the Web Audio API AnalyserNode. No audio data or microphone input is ever recorded, stored, or transmitted.

1 PATCH Patch Updates (v6.04.002)
PATCH v6.04.002
2026-10-03
  • Corner UI Loading Gate: Corner HUD controls wait for full visualizer readiness, eliminating flash-then-hide jank when booting in saved Zen mode.
  • Sim View Shader Pre-Compilation: Pre-compiles GLSL shaders during terrain build rather than stalling during reseed transitions.
MINOR v6.03.000
2026-09-30
  • Sim View: Dry Washes and Seasonal Streams: The Sim band shows SimPlane's new hydrology — pale sand washes where blue hairlines were, and streams that swell in spring and shrink by late summer. The four hand-tuned art bands are untouched.
  • Sim View Time and Season from the URL: Links can set the Sim view's time of day and season for that visit, and SimPlane's map button passes them.
MINOR v6.02.000
2026-09-30
  • Sim View: the Landscape Grew Up: The satellite Sim band shows everything SimPlane's terrain gained — corridors, fenced fields, shore margins, shallows, deltas, silt plumes, boats and traffic. The four hand-tuned art bands are untouched.
  • Sim View Map Locations Bounded Inward: Random map locations no longer show incomplete terrain at the viewport edge.
  • Band Loader Covers New SimPlane Modules: Sports pitches, landmarks, road traffic and boats load with the band in SimPlane's own script order.
MAJOR v6.01.001
2026-09-27
  • Earth SimPlane Observation Band: Integrated SimPlane's procedural terrain directly into Earth Observation mode as Sensor Band 1 with top-down aerial rendering, live atmospheric lighting, and time/season controls.
  • Fractal Observatory Mode: Dedicated visualizer mode with 7 distinct fractal families (Mandelbrot, Julia, Burning Ship, Tricorn, Celtic, Buffalo, Cubic Mandelbrot), GPU-accelerated orbit traps, fair radius normalization, and Minibrot visitors.

  • Craft-Relative Touch Joystick: Directional touch thumbstick for smooth mobile piloting.
  • Mode Cleanup & Screenshot Captures: Screenshot export captures Earth SimPlane band; visualizer mode swaps cleanly clear labels for constellations, spacecraft, and planes.
2 PATCHES Patch Updates (v6.01.002 – v6.01.003)
PATCH v6.01.003 2026-09-27
  • Responsive Earth Observation HUD Layout (css/styles.css): Optimized corner framing, Recon Telemetry HUD, and bottom-left sensor-band strip positioning across compact and mobile viewports to prevent HUD overlapping with corner controls.
PATCH v6.01.002 2026-09-27
  • Earth Observation: SimPlane Band No Longer Disappears After a Reload: Reloading or closing the page while the SimPlane view was loading counted as a crash and removed it from Shuffle for good on that device. Leaving the page no longer counts. A device is excluded only after two real crashes on the same release, and the exclusion lifts with the next release or after a week.
MINOR v5.11.001
2026-09-24
  • Earth Observation: Shuffle Mode & Sensor Bar Reflow: A new "shuffle" option joins the fixed sensor bands (badge, hotkey 5, control-panel entry) and is now the default on a first visit. The sensor-band bar moved to the bottom-left so it stops covering the now-playing indicator, and a bug that silently blocked clicks on the Q, Projects and Cosmos/Earth buttons in Earth mode is fixed. The Q menu and sensor bar now theme to Earth mode's green.
  • Earth Observation: Night Band Black-Screen Fix: A seeding bug could occasionally push the entire visible view to one side of the ocean/land divide, showing a solid black screen with no city lights on the Night band. Fixed and verified against thousands of reseeds.
  • Earth Observation: HUD Stays Toggleable in Zen Mode: The H hotkey/HUD button now works again while Zen Mode is active, instead of being forced off with no way to turn it back on.
  • Road Rendering: Painted street and artery edges are less jaggy, in both the visualizer and SimPlane's shared ground shader.
MINOR v5.10.001
2026-09-22
  • Earth Observation: Mini Plane Flybys (js/plane-flybys.js): Earth mode now gets its own flyby aircraft, the same way Cosmos view gets spacecraft — spawn one with the P key or a new control-panel button, click it for a label card and a "Fly" link that jumps straight into SimPlane with that exact plane selected. Every aircraft in SimPlane's own fleet is covered automatically, with a cabin "ding-dong" chime on spawn.
  • Earth Observation: Restricted to AGRI, Ambient Auto-Cycle (js/earth-observation.js, js/earth-observation-sim.js): The agricultural band now always renders through the richer sim terrain, so the old "V SIM" toggle is gone. Left alone, the view now drifts on its own — a random band and location every ~90 seconds, cross-fading smoothly between them — until you pick a view yourself.
  • Visualizer Toggle Made Public: The Cosmos/Earth toggle buttons in the Control Panel now show for every visitor, matching the O hotkey which was already public.
  • 1kx Projects Dropdown, Earth-Mode Colour (css/styles.css): The "1kx Projects" dropdown now matches the page's green Earth-mode colour instead of staying blue.
MINOR v5.09.001
2026-09-14
  • GPU Canvas Layer Release (js/celestial.js, js/engine.js): Released visualizer canvases (#canvas, #nebula-canvas, #star-canvas, #grid-canvas, #particle-canvas) from permanent GPU layer promotion at Tier 2+ (Low Power / Eco mode) to eliminate GPU memory strain on constrained devices.
  • Timer-Driven Remix Meter Loop (js/engine.js): Driven the remix meter animation loop from a setInterval timer (15 FPS at Tier 2 / 10 FPS at Tier 3) instead of requestAnimationFrame when running in constrained performance tiers.
  • Hoisted Device-Class Detection (js/engine.js): Hoisted device-class detection (isLowPowerDevice(), GPU vendor string checks) out of getNativeDPR()'s per-call path into a cached static initialization variable.
  • Unified Performance Tier System (js/celestial.js, js/spacecraft.js, js/constellations.js, js/engine.js): Standardized all 48 legacy isEcoMode / adaptiveRenderScale call sites across visualizer subsystems to use the unified performance tier system (getPerfTier()).
  • Tier-Aware Nebula Construction (js/celestial.js): Scaled nebula cloud particle allocation based on performance tier (50% reduction in Tier 2, 75% reduction in Tier 3).
  • Progressive Stem Quality Ladder (js/remix-engine.js): Extended default-bundle HD stem preloading reduction to the other stem channel using a 2-tier progressive quality ladder.
  • Debug HUD Precedence Fix (js/engine.js): Updated Debug HUD "Buffering [P0 Active]" status line to prefer live getActiveTrackPath() over stale _currentLoadedStemTrack memory-cache key.
7 PATCHES & 2 HOTFIXES Patch & Hotfix Updates (v5.09.002 – v5.09.008)
PATCH v5.09.008 2026-09-22
  • HD Stems Switch Together, Fixed (js/remix-engine.js): When the next track's stems had already started loading quietly in the background and then became the one you're playing, all four (drums, bass, vocals, other) could jump to full quality at once instead of one at a time. They now switch in individually as each one finishes, the same as a freshly-loaded track.
PATCH v5.09.007 2026-09-20
  • Tesla Crash Fix, Part 2 (js/sfx-engine.js, js/remix-engine.js): Ghost fragments and the dial tuner no longer decode a whole song just to play a fraction of a second. They now fetch and decode only a short slice of the MP3, cutting the memory each fragment needs from tens of megabytes to a few. The remix track cache also frees space before loading the next track, so track changes no longer spike memory.
  • Under-the-Hood Cleanup (js/*.js, css/styles.css): Removed unused code and styles, and the HD-stem buffering banner now updates only when its progress actually changes. No change to how the player looks or sounds.
PATCH v5.09.006 2026-09-19
  • Ghost Fragment Loudness (js/sfx-engine.js): Ghost fragments are capped by a per-gain-tier output limiter so the occasional over-loud one is tamed while quiet ones pass untouched. The two loudest modes (Spectral Shimmer, Vocoder Formant) are also turned down at the source, Paulstretch Freeze and Shortwave Morse are trimmed slightly, and the two wash modes are lifted a little. The Remix Console pads get the trims but skip the limiter.
  • Tesla Crash Fix (js/remix-engine.js): Fixed the remix track cache growing past its two-track cap, which could run an in-car browser out of memory after a handful of track changes.
  • In-Car Now Playing (js/audio-engine.js): The title no longer keeps its Remix tag after you switch remix off, updates right away when you toggle it, and reads Artist - Title. If the car drops the album-art download, it is retried every 25 seconds while music plays.
  • Studio Mixer Header (css/styles.css): The DSP, bypass and reset buttons now share the header row with the title on narrow screens, and the reset button is labelled RESET so it no longer clips. Aux-send rows are also spaced evenly on tablets.
HOTFIX v5.09.005.2 2026-09-17
  • Square Teardown & SFX Module Recovery (js/audio-engine.js, scripts/upload.py, scripts/validate.js): Guarded fadeAndPause() teardown against missing SFX references so audio always pauses cleanly upon square close, restored js/sfx-engine.js and modular scripts to the deployment manifest, and enforced structural validator checks on HTML script tags.
HOTFIX v5.09.005.1 2026-09-17
  • MediaSession Album Art & Transport Recovery (js/audio-engine.js, js/remix-engine.js, js/sfx-engine.js): Prioritized track-specific 512px cover art over artist logos for in-car MediaSession displays, enforced continuous advance flag resets on pause, zeroed stem meter CSS transforms on stop, and added channel fallback handling for tape stop breakdown effects.
PATCH v5.09.005 2026-09-17
  • Audio Context & Test Port Synchronization (js/audio-engine.js, tests/test_monorepo_regression.js): Consolidated user gesture AudioContext unlock paths across crossfade and stem engine callbacks, and assigned explicit free CDP test ports per worker to prevent socket collisions during automated validation runs.
PATCH v5.09.004 2026-09-16
  • Audio Engine & Layout Stability (js/audio-engine.js, css/styles.css): Resolved rapid track swap race condition, enforced artist shuffle catalog rotation rule, fixed REMIX status badge sync, and stabilized autopilot ticker layout.
MINOR v5.08.001
2026-09-09
  • Unified Four-Step Quality Ladder (js/celestial.js, js/engine.js, js/dashboard.js): Collapsed the separate LOD tier system and Eco Mode toggle into a single ladder — Tier 0 (Full Quality), Tier 1 (Balanced), Tier 2 (Eco Mode), Tier 3 (Minimal). One control now cycles Auto through Tier 0–3 in place of two competing switches.
  • Frame-Drop-Ratio Tier Thresholds (js/engine.js): Tiers now change on 20.8 / 25.0 / 33.3 ms average frame time — 25%, 50% and 100% frame-drop ratios at 60 Hz — rather than round FPS figures that hide vsync quantisation. Recovery thresholds are stricter than degrade, with a hold period, so the ladder cannot oscillate at a boundary.
  • Remix Background Freeze Fix (js/celestial.js, js/engine.js): The 12× auto-pixelation and the background freeze keyed off different conditions, so a remix track playing with the Remix Console closed pixelated the background and then kept animating it at full rate. Both now share one predicate; at Eco Mode and below the background freezes whenever a remix plays.
  • HD Stem Delivery Payload (music/stems/, js/remix-engine.js): Re-encoded all 221 stem sets from measured evidence, reducing the library 6.0 GB to 4.3 GB. Added a throughput budget so a slow-but-alive connection falls back to the DSP crossover instead of buffering indefinitely, and a connection-aware default for Data Saver and 2g links.
  • Cache Correctness (sw.js, js/engine.js): Service worker audio cache bumped so returning visitors receive the re-encoded stems, and the album-art metadata cache is now bounded rather than growing for the life of the page.
  • Service Worker Scope Fix (sw.js): The service worker registered with no explicit scope, which defaults to the directory of the script file rather than the page — living under js/, it had never actually controlled the page or intercepted a single fetch, silently, for as long as it existed. Moved to the site root so the default scope covers the page; a new validator check enforces this structurally going forward.
  • Real-Browser UI Regression Suite (tests/test_browser_ui.js): New suite driving headless Chrome — 28 assertions covering computed styles on the resolved cascade, square lifecycle, track-swap ordering and cache bounds. 540 Music Player and 112 Remix assertions passing; full monorepo validation green.
4 PATCHES Patch Updates (v5.08.002 – v5.08.005)
PATCH v5.08.005 2026-09-13
  • HD Stem Blob Missing MIME Type (js/remix-engine.js): The streaming stem download path built the final audio Blob with no MIME type, leaving <audio> to content-sniff raw bytes to recognize it as audio — a heuristic that could silently fail under real load, so a stem could download to ~99% and never actually become playable, triggering a fallback to DSP for the whole track. Fixed by threading the response's real Content-Type header into the Blob.
PATCH v5.08.004 2026-09-13
  • HD Stem Throughput Budget — Per-Stem Judgment (js/remix-engine.js): Loosened the give-up thresholds and replaced the purely aggregate throughput check with per-stem judgment, so one slow or stalled stem can no longer drag down (or hide behind) its siblings' progress.
  • Next-Track Stem Preload Anticipation on Give-Up (js/audio-engine.js, js/remix-engine.js): Bandwidth freed by a failing stem fetch now immediately goes toward preloading the next continuous-play track instead of sitting idle until the fixed 30-second anticipation mark.
  • Mixer HD Badge Layout (index.html, css/styles.css): The per-channel "HD" badge now sits inline next to the channel name instead of wrapping to its own line.
  • Debug HUD Bridge State Accuracy (js/engine.js): "Buffering HD Stems" status now correctly distinguishes DSP Bridge Active from Playing Original (Bypassed).
  • Service Worker Streaming Fix (sw.js): Audio cache writes now happen in the background instead of blocking the response, restoring progressive/streamed playback through the service worker.
PATCH v5.08.003 2026-09-10
  • Tesla Aw-Snap OOM Crash Fix (js/audio-engine.js): Capped decoded AudioBuffer cache in js/audio-engine.js at 2 concurrent tracks with automatic LRU pruning, preventing out-of-memory crashes on Tesla in-car Chromium browser tabs during continuous listening.
  • Remix Console Autopilot Row Redesign (index.html, css/styles.css): Redesigned the Autopilot controls header row into a compact, stable-width flex layout, eliminating layout shifts when toggling DJ modes or telemetry states.

Background stars spiral 3-5 orbits inward over ~4.0-5.5s; reaching the event horizon (< 14px) triggers singularity consumption, stardust sparkle bursts (spawnSparkle), and seamless star resetting.
  • Unified 9-Spacecraft Gravitational Physics Engine (updateSpacecraftGravityPhysics): Consolidated physics across all 9 spacecraft classes (Voyager, JWST, Skylab, Discovery One, Space Shuttle, ISS, Sputnik, Hubble, Cassini-Huygens). Spacecraft entering gravity wells undergo distance-proportional orbital capture, progressively shrinking in scale (scaleMult) as they spiral into the funnel. Event horizon entry (< 14px) consumes the craft with 16 sparkle bursts and acoustic shockwaves (spawnAcousticShockwave).
  • Gravitational Slingshot Ejection: Releasing active gravity wells before total consumption launches spacecraft into high-speed slingshot free-flight (slingshotPower), emitting sparkle propulsion trails before smoothly decaying back to cruise speed. Trajectory banking (lerpAngle) aligns spacecraft heading perfectly along curved accretion spirals and slingshot paths.

  • Expanded monorepo regression test suite to 285/285 passing assertions.
PATCH v2.23.003
2026-08-18
  • Distance-Proportional Slingshot Speed & Particle Burst Scaling (index.html): Captured distToWell during active gravity well pull in updateSpacecraftGravityPhysics. On gravity well release, calculated release proximity ratio (proxFactor = Math.pow(proximity, 1.2)), scaling slingshot ejection speed dynamically from a subtle 5-15% velocity nudge at the perimeter (~550px) up to a perfectly balanced, controlled orbital launch (~6.0–7.0 px/frame) deep inside (< 100px). Scaled particle burst count (sparkleCount = Math.round(2 + proxFactor * 12)) and particle size dynamically with release proximity.
PATCH v2.23.002
2026-08-17
  • Space Invader Orthogonal Evasive AI Navigation & Singularity Avoidance: Replaced passive orbital gravity pull on SpaceInvaderCraft with an active threat detection radar (avoidRadius = 320). When an active black hole / gravity well is nearby, Space Invader flags isEvading = true and executes strict orthogonal evasive maneuvers (pure horizontal side-steps or pure downward descent) to escape consumption while preserving authentic 8-bit arcade grid alignment. Accelerates stepping speed up to 3.8x during evasion and emits rapid retro pixel trail particle bursts (trailInterval = 4).
MINOR v2.13.001
2026-08-10
  • Voyager Spacecraft Easter Egg (index.html): Added VoyagerCraft class that animates a tiny Voyager probe drifting across the starfield along a quadratic Bézier arc. First pass appears 30–90 seconds after page load; subsequent passes recur every 3–10 minutes. Accessible via 'v' keyboard shortcut (scheduleNextVoyager). Voyager state tracked in state.voyagers[].
  • #song-progress-container Drag Exclusion (index.html): Added #song-progress-container to the background drag exclusion list, preventing accidental comet launches when the user drags the song progress scrubber.

MINOR v2.12.001
2026-08-06
  • Artist Selection Popup Controls (index.html): Added interactive artist logo toggle buttons to the lower-left modal ("About 1kx.org"). Logos toggle between full color ("ON") and black & white grayscale ("OFF") to filter which artists spawn squares on screen. Features single-select focus when clicking an artist from all-selected state, reset-to-all when attempting to deselect the last remaining active artist, and localStorage filter preference persistence (1kx_selected_artists).
1 PATCH Patch Updates (v2.12.002)
PATCH v2.12.002
2026-08-06
  • Preloader Pool Artist Filter Eviction (index.html): Added strict artist selection validation to fillPreloadPool(), manageSpawning(), and toggleArtist(). In-flight background preloads and queued off-screen tracks belonging to unselected artists are automatically discarded and their memory Blob URLs revoked, guaranteeing no unselected artist square appears on screen while allowing active on-screen squares to finish playing naturally.
MINOR v2.11.001
2026-08-06
  • Slow Connection Typewriter Overlay (index.html): Added a centered typewriter overlay that triggers if no square is loaded after 10 seconds, displaying a blinking cursor for 2 seconds followed by a character-by-character "loading...." animation until a square finishes preloading.

MINOR v2.10.001
2026-08-04
  • Service Worker Audio Range Caching: Configured CacheStorage (1kx-audio-cache-v1) in js/sw.js to serve HTTP 206 Partial Content slices directly from memory/disk cache without hitting the network.
  • Pre-Appearance Audio Preloader Architecture: Implemented off-screen fillPreloadPool() and state.preloadPool. Pre-fetches 256KB head slices, generates audioBlobUrl, and decodes Web Audio primedAudioBuffer off-screen before squares appear on screen.
  • Strict 1-at-a-Time Preloading (PRELOAD_POOL_SIZE = 1): Limits off-screen preloading to 1 track at a time, eliminating extra background downloads and preserving mobile cellular data.
  • Progressive Spawning & Reset Sequence: Square 1 appears at >= 3s after page load; Square 2 appears at >= 10s after Square 1; subsequent squares follow an ever-increasing delay curve up to 43 squares. Automatic reset occurs when all squares are closed.
  • In-Place Logo Reveal & Hardware 3D Transforms: Positioned floating squares with CSS translate and targeted .glitch-play on the artwork overlay for smooth, in-place logo reveals without position jumps.
  • Spontaneous Background Comets: Periodic shooting stars arc across the starry sky (first within 10s of load, subsequent comets every 1–3 minutes).

  • Visual Debugger Counter & Test Suite Hardening (index.html & tests/): Corrected On-Screen Ready count filtering to exclude active network buffering squares (loading-active), and unmocked runtime engine gates in automated regression testing (test_preloader.js & test_monorepo_regression.js).
PATCH v2.10.024
2026-08-06
  • Visualizer Spawner Gate (index.html): Resolved bug in areAllSquaresPreloaded() that looked for legacy primedAudioBuffer instead of audioBlobUrl, eliminating single-square spawning stalls and restoring automatic multi-square visualizer flow.
PATCH v2.10.023
2026-08-06
  • Preloaded Track Playback & Loading Spinner Stalls (index.html): Resolved issue where preloaded tracks bypassed in-memory Blob URLs during channel pre-warming, guarded onwaiting/onstalled events against local media blob misfires, added oncanplay listeners, and ensured .catch() on audio.play() clears loading state on play interruptions.
PATCH v2.10.022
2026-08-06
  • Audio Debugger Control Panel Toggle Button (index.html): Added a dedicated Debugger toggle button to the main control bar for convenient access to the 1KX Audio Debugger panel, and unified secret hotkey triggers (1kx & xxx).

  • Seamless Prebuffered Audio to HTML5 Streaming Handoff (index.html): Deferred Web Audio buffer fade-out in audio.onplaying until HTML5 audio completes its seeked event when playhead alignment (elapsed > 0.15s) requires seeking, and skipped seek stalls when time difference is minimal (<= 0.15s). Eliminates audio cutouts, silent gaps, and decoder seek stalls during prebuffered track playback handoffs.
PATCH v2.10.012
2026-08-04
  • ID3 Metadata Offset Audio Preloading Fix (index.html): Updated fillPreloadPool() to inspect ID3v2 header tag sizes (10 + tagSize) and slice pure audio frames past embedded cover art headers for Web Audio decodeAudioData() buffer priming. If ID3 artwork headers exceed 256 KB, a secondary range request fetches 128 KB of pure audio frames directly past the ID3 tag offset. Guarantees 100% preloader success and equal round-robin representation across all artists (Caseyland, Creme Puffs, Uphill Driver, Orange Cricket Project) on page load.
PATCH v2.10.011
2026-08-04
  • Dynamic Script & Service Worker Cache-Killers (index.html): Added mode-aware version/timestamp cache-buster queries (?v=2.10.011 for production, ?t=TIMESTAMP for local dev) to <script src="js/mp3tag.min.js"> and navigator.serviceWorker.register('js/sw.js').

PATCH v2.10.009
2026-08-04
  • Closed-Artist Avoidance (index.html): Configured Square.destroy() to record lastClosedArtist and updated pickBestArtist() in getNextTrack() to exclude lastClosedArtist when spawning replacement squares. Guarantees that newly loaded squares avoid matching the artist of the square that was just closed.
PATCH v2.10.008
2026-08-04
  • First Square Random Artist Selection (index.html): Configured pickBestArtist() to select a completely random artist with equal 25% probability when loading the very first square (lastLoadedArtist === null) on page boot or full state reset. Subsequent squares dynamically seamlessly follow the round-robin least-represented representation engine.
PATCH v2.10.007
2026-08-04
  • Deterministic Round-Robin Tie-Breaker (index.html): Enhanced pickBestArtist() helper in getNextTrack() to perform a round-robin rotation through ARTIST_LIST (currentArtistIndex) whenever multiple artists tie for least-represented on screen. Ensures predictable cyclic artist selection while enforcing non-consecutive same-artist square loads.
PATCH v2.10.006
2026-08-04
  • Balanced Artist Selection Rules (index.html): Updated getNextTrack() artist selection engine to enforce two rules when spawning or loading new squares: (1) Avoid using the same artist as the last-loaded square, and (2) Prioritize the artist who is least-represented on screen at the moment (fewest active squares).
PATCH v2.10.005
2026-08-04
  • Service Worker 206 Partial Cache Truncation Fix (js/sw.js): Updated sw.js (1kx-audio-cache-v2) to cache ONLY HTTP 200 OK responses under canonical track URLs in CacheStorage. Bypassed CacheStorage for HTTP 206 partial range requests (256KB head slices), resolving audio playback truncation and loop-restart issues.
  • Strict Spawning & Buffering Guard (index.html): Updated areAllSquaresPreloaded() to block spawning new squares if ANY square on screen is in loading-active (buffering/spinning) state or lacks a verified primedAudioBuffer.
  • Web Audio to HTML5 Audio Playhead Position Sync (index.html): Recorded squareInstance.primedStartTime and synced audio.currentTime to elapsed Web Audio duration upon audio.onplaying, eliminating playhead jumps and restarts when transitioning from buffer priming to streaming audio.
PATCH v2.10.004
2026-08-04
  • Preloader Async Web Audio Decoding (index.html): Awaited ctx.decodeAudioData(sliceToDecode) inside fillPreloadPool(), ensuring that primedAudioBuffer is fully resolved before off-screen track payloads are pushed into state.preloadPool and spawned onto the canvas. Eliminates buffering spinners on Slow 4G connections.
PATCH v2.10.003
2026-08-04
  • Instant 0ms Visual UI & Artwork Reveal (index.html): Extracted revealActiveSquareArtwork() helper to immediately hide the loading spinner, reveal artist logo artwork, and trigger in-place play glitch upon clicking a preloaded square. Eliminates visual spinner stalling while HTML5 <audio> buffers in the background on Slow 3G.
PATCH v2.10.002
2026-08-04
  • Service Worker 206 Partial Content Range Caching (js/sw.js): Updated Service Worker fetch handler to cache both 200 OK and 206 Partial Content range responses in CacheStorage under their canonical track URLs (/music/...). Fixed a bug where partial Range responses were excluded from cache.put().
  • Zero-Stall Network Stream Handoff (index.html): Assigned canonical track URLs (getTrackUrl()) to audio.src so HTML5 <audio> requests are 100% intercepted by Service Worker CacheStorage, delivering instant 0ms audio playback on throttled Slow 3G connections.
MINOR v2.9.0
2026-07-09
  • Continuous Range Interception: Intercept all music range requests (not just those starting at 0) and delegate subsequent chunks to fetch(request) inside event.respondWith(). This ensures that browsers see the audio stream as coming continuously from the Service Worker, resolving Safari and Chrome media engine stalling and network error blocks.

PATCH v2.9.8
2026-07-31
  • LiamBot Integration Suite (v0.01.12 – v0.01.23):
  • System prompt refinements expanding domain knowledge across architecture, engineering, design, music, computer science, and astronomy.
  • Flat vector SVG icons for header brand badge, chat history avatars (bot & user), lock button, settings gear, password eye toggle, shuffle button, and prompt headings.
  • Interactive features: Password visibility toggle (eye icon), 5-day cookie persistence, daily welcome banner topic rotation, and touch-snap mobile prompt card carousel.
  • UX fixes: Smooth window scrolling on prompt click, input focus scroll jump prevention (preventScroll), and generic follow-up action pills.
  • FOOTBALL Mini-App Updates (v0.1.0 – v0.5.5):
  • Telstar pentagon pixel art soccer ball design with soft color contouring and high-res loading screen graphic.
  • Touch joystick with dual-ring walk/sprint zones, dynamic pull distance scaling, and desktop key hold acceleration.
  • Dribble/kick mechanics with 15-frame kick cooldown, directional aiming, high-DPI instruction UI, and color-coded goal netting.
  • Version Release: Updated package configuration and homepage settings dashboard to version 2.9.8.
PATCH v2.9.8
2026-08-01
  • Pixelated Soccer Ball Asset: Replaced soccer ball emoji (⚽) in the top-right sub-app link with an 8x8 pixel-art canvas ball matching the retro design from /Football.
  • Dynamic Sub-App Image Synchronization: Implemented client-side synchronization (syncFootballBallFromGame()) that fetches /football/game.js at runtime, parses ballSprites and drawBallSprite color mappings, and renders the exact pixel ball from /Football dynamically so future ball artwork changes automatically propagate to the main homepage.
PATCH v2.9.7
2026-07-31
  • Background Desktop Drag-to-Comet: Clicking and dragging across the background on desktop now launches a shooting star comet in the direction of the drag, mirroring the mobile swipe gesture.
  • Pointer Event & Touch Layering: Resolved event blocking where #canvas-container prevented clicks on the soccer ball and touch swipes on mobile. Moved interaction event listeners (mousedown, touchstart, touchmove, touchend) to window with targeted UI element filtering so squares float on top visually without blocking clicks or comets.
PATCH v2.9.6
2026-07-31
PATCH v2.9.7
2026-07-31
  • Permanent Subagent Definitions: Added permanent, token-optimized subagent definitions in .agents/agents/ (Orchestrator, Developer, QA Tester, and Release Manager).
  • Soccer Ball Roll-In Animation: On initial appearance after the 5-second delay, the football link now rolls in from the right with a counterclockwise 540° rotation decelerating via cubic-bezier ease-out over 1.3 seconds, rather than a plain fade.
  • Mobile Settings Panel Access: Long-pressing (800ms, no movement) in the bottom 20% of the screen now opens the settings panel on mobile devices, excluding interactive elements like sliders and buttons.
  • Sub-App Navigation Links: Added Football and CaseyCase navigation links directly inside the settings panel header.
  • Flat SVG Play/Pause Icons: Replaced emoji ⏸/▶ icons in the Pause/Play button with inline SVGs matching the flat style of the Recolor button.
  • Soccer Ball bfcache Reset: When navigating back from the Football app via the browser back button, the soccer ball now resets — disappears immediately and rolls back in after a fresh 5-second delay.
  • Soccer Ball Click Animation: Clicking the soccer ball now spins fast for 1 second (down from 1.5s) before navigating to the Football app.
  • Mobile Settings Header Layout: Settings panel header stacks vertically on narrow screens (≤600px) — title on row 1, links and square counter on row 2 — to prevent text overflow.
  • Long-Press Text Selection: Added -webkit-user-select: none and -webkit-touch-callout: none to the body to suppress iOS Safari text selection and the copy/share callout bubble during long-press gestures. Text selection inside the settings panel remains enabled.
  • Soccer Ball Spinning Animation Regression: Fixed a closure bug where the spinning-fast class was being applied to a detached (cloned) DOM element, making the click spin animation invisible. The click handler now correctly references the live DOM element.
PATCH v2.9.6
2026-07-30
  • Delayed Football Link: Added a tiny soccer ball emoji link in the upper right-hand corner that fades in after 5 seconds, linking directly to the Football sub-application (football/).
  • Hover Spin Animation: Soccer ball slowly rotates on hover (spin-slow, 4s linear).
  • Click Fast Spin: Clicking/tapping the soccer ball triggers a fast spin animation before navigating to the Football app.
PATCH v2.9.5
2026-07-14
  • High-DPI (Retina) Canvas Resolution Scaling: Integrated devicePixelRatio scaling dynamically for the background canvas on startup and resizing, ensuring razor-sharp starfield details on all High-DPI and modern mobile viewports.
  • GPU-Optimized Sparkle Rendering: Replaced heavy vector circle path drawings (ctx.arc()) inside stardust particles with high-performance ctx.fillRect() blocks to avoid CPU path calculations and GPU draw-state switches on intense starbursts.
PATCH v2.9.4
2026-07-14
  • Trajectory curvature: Shooting stars now travel along a randomized, circular curved trajectory.
  • Sparkle trails: Shooting stars emit subtle, fading stardust sparkles along their path using high-performance particle pooling.
PATCH v2.9.3
2026-07-14
  • Background touch-swipe shooting star gesture feature for mobile/tablet devices. Swiping across a blank space on the canvas launches a fast-moving star with a fading light trail in the direction of the swipe gesture.
PATCH v2.9.2
2026-07-09
  • Active Service Worker Unregistration & Cache Purging: Reconfigured sw.js and root index.html to actively unregister any existing range-caching Service Workers and clear all cache keys. This cleanses the client browsers of stale range caching routines and restores 100% stable native audio streaming.
PATCH v2.9.1
2026-07-09
  • Selective Range Interception Bypass: Simplified sw.js to ONLY intercept the 128KB metadata range requests (bytes=0-131072) sent by the parser/preloader, completely bypassing Service Worker interception for playback requests (bytes=0- or subsequent chunks). This offloads media streaming back to the browser's native range handling, eliminating browser-specific playback stalling bugs and restoring instant start response natively.
MINOR v2.8.0
2026-07-02
  • Fallback Logo Preloading: Upgraded fallback artist logos from low-priority prefetch to high-priority HTML preload link relations.
  • Programmatic Image Pre-decoding: Instantiated logo image objects dynamically via JavaScript at startup, forcing early memory caching and rendering decode states to eliminate visual "painting" delays during playback starts.
9 PATCHES Patch Updates (v2.8.1 – v2.8.9)
PATCH v2.8.9
2026-07-09
  • Service Worker 206 Caching Block: Rewrote sw.js to store 128KB metadata range requests under a 200 OK status (remapping original headers as custom metadata) to bypass the browser Cache API's strict blocks and TypeErrors on 206 statuses.
  • Playback Start Interceptor: Serve sliced cached blobs to <audio> elements starting at 0 natively.
  • Preloader URL Alignment: Updated processPreloadQueue() in index.html to resolve track paths using getTrackUrl() (complying with segments URL encoding), resolving Cache API key match failures.
PATCH v2.8.8
2026-07-08
  • Particle Object Pooling: Redefined stardust Sparkle class and implemented a pre-allocated circular object pool of 300 sparkles to eliminate garbage collection (GC) pauses and runtime allocation overhead during collisions or background clicks.
  • Debounced Settings Sliders: Throttled/debounced the Squares and Stars count settings sliders by 150ms to prevent layout reflow thrashing during drag interactions while keeping label readouts instant.
PATCH v2.8.7
2026-07-08
  • Media Resource Release: Optimized visualizer Square class destroy() cleanup to explicitly reset the HTML5 <audio> element's src attribute to '' and call load(). This releases all media buffer memory and open connection sockets in mobile/desktop browsers when squares are destroyed or paused.
PATCH v2.8.6
2026-07-08
  • Background Audio Idle Preloader: Introduced a throttled, sequential queue processor (processPreloadQueue) that preloads the first 128KB chunk of all visible squares during browser idle times (requestIdleCallback).
  • Root Service Worker Range Interceptor: Recreated root-level sw.js to cache 128KB chunks under metadata range queries (bytes=0-131072) and instantly resolve playback starts (bytes=0-) locally from Cache Storage as partial content.
  • Queue Test Suite: Created tests/test_preloader_queue.js and added fetch mocks in existing runners to verify queue states and visual indicator class changes.
PATCH v2.8.5
2026-07-08
  • Visualizer Spawner adding/removing Cycle: Configured the visualizer spawner loop to alternate between adding squares up to targetCount and removing oldest inactive squares back down to 1 square.
  • Playing/Paused Protection: Implemented checks to skip removing squares that are actively playing or paused on audio channels.
  • CRT TV Collapse Transition: Evicted squares transition out using the tv-off class CRT TV turn-off animation.
  • Cycle Test Suite: Created tests/test_spawner_cycle.js to verify mode transitions, target count checks, playing square skips, and tv collapse animation hooks.
PATCH v2.8.4
2026-07-08
  • Unique Song Signatures Filter: Introduced a signature checker (getSongSignature) that prevents squares from loading the same artist and song title as any other currently displayed square.
  • Signature Test Suite: Created tests/test_unique_signatures.js to ensure signature extraction works on various filename templates and duplicate signature exclusions are verified during grid fills.
PATCH v2.8.3
2026-07-07
  • Delayed Custom Artwork Transition: Modified playback initialization to display the fallback artist logo for exactly 1 second when play begins, after which it executes a glitch transition to custom metadata album artwork (if present).
  • Destructor Cleanups: Clear active transition timers inside destroy() to prevent background timeout execution leaks.
PATCH v2.8.2
2026-07-02
  • Inline Artist Logos: Embedded a very small, rounded version of each artist logo (1.1rem width/height) next to the bullet points inside the info panel collective description.
  • Flexbox List Layout: Replaced the absolute-positioned pseudo-bullets with a flexbox alignment (display: flex; align-items: flex-start;) to ensure clean alignment and neat indents for wrapped text lines.
PATCH v2.8.1
2026-07-02
  • New Artist Integration: Added "Orange Cricket Project" (1993-2000) to the visualizer and info panel details.
  • Orange Color Scheme: Configured the HSL-seeded palette to generate shades of orange (Hues 15-45) for Orange Cricket Project visualizer squares.
  • Automatic Track Sync: Synced 15 new tracks locally and updated the primary catalog array in index.html.
  • High-Resolution Logo Preloading: Formatted and integrated the upscaled high-resolution logo preview as a PNG in preloading link tags and programmatic pre-decoders.
MINOR v2.7.0
2026-07-02
  • Network & Count Adaptive Spawning: Optimized the spawning delay formula inside manageSpawning() to increase progressively as the canvas becomes populated (1 + Math.pow(current, 1.2) * 0.25), preventing immediate screen overcrowding. Also introduced a network-adaptive factor (getConnectionDelayFactor()) via the browser's Network Information API, scaling delays up on slower connections (up to 3.0x delay multiplier on 2G/3G networks) to match media stream pacing.
3 PATCHES Patch Updates (v2.7.1 – v2.7.3)
PATCH v2.7.3
2026-07-02
  • Buffering Pulse Tuning: Fine-tuned the active square buffering pulse shadow (loadPulseFast) to a middle ground (11px spread, 0.30 opacity), balancing softer aesthetics with clear buffering indications.
PATCH v2.7.2
2026-07-02
  • Buffering Pulse Tuning: Reduced the active square buffering pulse glow (loadPulseFast) spread by half (from 16px to 8px) and lowered its glow opacity (from 0.45 to 0.22) to make the visual indicator softer and less intense.
PATCH v2.7.1
2026-07-02
  • GitHub Actions CI/CD Pipeline: Added .github/workflows/ci-cd.yml to automatically execute python syntax checking and Jest-based integration tests upon push, and deploy to FTP when green.
  • Repository Testing Assets: Migrated check_syntax.py and test_preloader.js from internal sandbox folders directly into the repo for workflow portability.
  • Credentials Redaction: Redacted hardcoded FTP passwords from upload.py to prevent repository leaks, shifting configuration to .env files and environment parameters.
  • Git History Purge: Rewrote and force-pushed repository history to completely wipe all past trace occurrences of production secrets.
MINOR v2.6.0
2026-07-02
  • Service Worker Caching Optimization: Replaced streaming-based fetches with a two-stage Range-header fetch mechanism inside extractAlbumArt(). The first stage requests a 128KB chunk (bytes=0-131072) matching the Service Worker's cache key to hit the cache storage instantly on subsequent plays. If cover art tags exceed 128KB, a second request downloads only the remaining bytes and combines them.
4 PATCHES Patch Updates (v2.6.1 – v2.6.4)
PATCH v2.6.4
2026-07-02
  • Artwork Synchronization Race Condition: Replaced browser-specific checks on the audio.paused property inside metadata parsing callbacks with a custom playbackStarted state property initialized on Square instances. This prevents browser-specific buffering states from prematurely flagging playing tracks as paused, guaranteeing that custom cover art renders reliably on the visualizer squares.
PATCH v2.6.3
2026-07-02
  • Deferred Album Artwork Transitions: Synchronized the cover art overlay updates with the Now Playing metadata text. When switching tracks, the previous track's artwork remains active on its square while the new track buffers/loads. Only when the new track's onplaying event fires, do we hide the old artwork, reveal the new artwork, and run the transition glitch.
PATCH v2.6.2
2026-07-02
  • Starfield Canvas Draw Call Optimization: Removed slow ctx.save() and ctx.restore() stack operations inside Star.draw(). Instead, it caches and restores only the ctx.globalAlpha property directly. This eliminates 12,000 stack operations per second for the 100 continuously rendering background stars, significantly reducing CPU rendering overhead and preventing visual lag.
PATCH v2.6.1
2026-07-02
  • Mobile Viewport Text Marquee & Progress Underline: Added min-width: 0 to #song-info-wrapper and set width: 100% on #song-title-container. This allows the text containers to shrink dynamically to the visible screen width on small viewports, restoring text scrolling marquee behaviors and restricting the progress line within visible bounds.
MINOR v2.5.0
2026-07-01
  • Preloading System Rollback: Removed all background audio preloading queues, off-screen spawning restrictions, and download throttling. Reverted to a direct click-to-play architecture where squares spawn immediately on page load/destruction, eliminating background network consumption, port blockages, and preloader-induced desync bugs.
  • Static Channel Track Loading: Reconfigured the audio engine to load tracks directly onto static, permanent HTML Audio elements, resolving Web Audio routing errors and layout mismatches.
9 PATCHES Patch Updates (v2.5.1 – v2.5.9)
PATCH v2.5.9
2026-07-02
  • Fallback Logo Asset Prefetching: Added HTML5 <link rel="prefetch"> headers for the default artist logos (logo_caseyland.png, logo_uphill_driver.png, logo_creme_puffs.png) inside the <head> of the page. This preloads the fallback logos in the background during idle periods, guaranteeing instant logo loading when starting playback on slow connections.
PATCH v2.5.8
2026-07-02
  • Now Playing Timing Refinement: Postponed Now Playing UI text/color updates during track switches so that the previous song's artist/title remains visible while the new song loads. The play/pause button spinner immediately displays the new loading square's color, updating the text marquee only when the new song starts playing.
PATCH v2.5.7
2026-07-02
  • Square Spawning Limits: Removed the obsolete allPlayable check from manageSpawning(). Since preloading was rolled back, the playable check incorrectly blocked new squares from spawning, capping the active count and preventing adjustments from the settings panel.
PATCH v2.5.6
2026-07-02
  • Playback Progress Underline: Added a subtle progress indicator underline directly beneath the Now Playing song title text. The progress line dynamically inherits the color of the active square, scales its width to match either the text width or visible container bounds (if scrolling), and fills from left to right as the track plays.
PATCH v2.5.5
2026-07-02
  • Dynamic ID3v2 Tag Block Parsing: Integrated dynamic synchsafe tag block size parsing inside extractAlbumArt(). It parses the exact header size (which can exceed 500KB for high-resolution embedded cover art) from the file's first 10 bytes and streams only the necessary header data, preventing truncated header objects from failing tag parsing.
PATCH v2.5.4
2026-07-01
  • Continuous Play ReferenceError: Removed obsolete processPreloadQueue() call from Square.shrinkAndDestroy(), fixing the ReferenceError that broke track sequences.
  • Local-Only Error Overlay Alerts: Configured window error and promise rejection visual alerts to only display on local development sites (isLocal protocol/domain matches), preventing diagnostic UI boxes from showing up on production while retaining them for local debugging.
PATCH v2.5.3
2026-07-01
  • Stream-Based Metadata Extraction: Swapped the byte-range metadata request fetch with a stream-based reader. This solves the missing production album art bug caused by IIS returning 416 errors for range headers, enabling metadata art extraction to succeed and load with a glitch effect.
PATCH v2.5.2
2026-07-01
  • Service Worker Range-Request Caching: Implemented a service worker (sw.js) that caches the initial 128KB metadata range requests of audio tracks. When playing, the Service Worker immediately satisfies the start of the stream from the local cache, yielding near 0ms start latency while the rest of the file streams seamlessly.
  • Interactive Canvas Starburst Effect: Added mouse and touch listeners on empty visualizer background space to spawn custom Sparkle bursts in a starfield pattern, enhancing kinetic page feedback.
PATCH v2.5.1
2026-07-01
  • Now Playing Section Responsiveness: Configured updateNowPlayingUI() to update the song marquee and slide-in container immediately upon clicking a visualizer square. This bypasses asynchronous timing differences on devices where the HTML5 playing event behaves inconsistently, rendering Now Playing metadata instantly when a track is requested.
MINOR v2.4.0
2026-07-01
  • Starfield Canvas Pre-rendered Glow Texture: Pre-rendered the radial star glow texture onto a single cached off-screen canvas once at startup. In the animation loop, Star.draw() uses GPU-accelerated ctx.drawImage to copy the texture, scaling and adjusting opacity dynamically. This completely removes thousands of expensive vector radial gradient rendering passes per second from the frame ticks.
9 PATCHES Patch Updates (v2.4.1 – v2.4.9)
PATCH v2.4.9
2026-07-01
  • Browser-Native CSS Image Loading: Simplified showArtwork() and hideArtwork() to set the CSS background-image directly on the overlay element rather than preloading via new Image() in JavaScript. This allows the browser to natively load, cache, and render the artwork overlays, resolving issues where transient network errors or image loading timeouts prevented artwork or default fallback logos from displaying.
  • Global Channel Playback Check: Modified the artwork callback inside extractAlbumArt() to display the artwork if the square is playing on any channel, resolving a race condition where the callback did not render because activeChannelIndex had toggled during crossfades.
PATCH v2.4.8
2026-07-01
  • Fetch-and-Blob Audio Preloading: Integrated a robust HTTP fetch pipeline to download the entire audio file into a local memory Blob before playback starts. Passing the resulting blob: Object URL to the Audio element guarantees instant 0ms latency playback when clicking preloaded squares, bypassing browser range request throttle queues on throttled network connections.
  • Memory Leak Protection: Configured automatic Object URL revocation via URL.revokeObjectURL() during square destructions.
  • Fetch Abort Integration: Used AbortController signals to cleanly abort pending fetches when background downloads are suspended or prioritised.
PATCH v2.4.7
2026-07-01
  • Artwork Race Condition Fix: Tracked this.artworkLoadingUrl on each square so that pending image loads are automatically discarded when hideArtwork() is called. This solves a desync where an old square's artwork would load asynchronously and display on screen even after clicking a different square.
  • Pause Responsiveness Fix: Configured fadeDirection = 'in' and 'out' tracking. User clicks are no longer ignored during active fade-ins, allowing instant second-click pause/close operations.
  • Explicit Channel Parameter: Updated fadeAndPause to receive the channel reference explicitly to bypass global channel index lookups.
PATCH v2.4.6
2026-07-01
  • Async Closure Capture Bugfix: Fixed a JavaScript error where transitioning tracks triggered an async onerror event callback which read newChan.audio.src after the channel's audio element had already been set to null by the preceding cleanup tick. Capturing the audio reference in local closure scope during callback assignment solves this race condition.
  • Additional Callback Cleanups: Cleared onerror listeners explicitly when swapping tracks and destroying squares.
PATCH v2.4.5
2026-07-01
  • Uncaught TypeError Bugfix: Fixed a JavaScript error in Square.destroy() where resetting callbacks on chan.activeSquare.preloadAudio threw an exception because this.preloadAudio had already been set to null in the preceding cleanup block. Accessing chan.audio directly resolves the exception safely.
PATCH v2.4.4
2026-07-01
  • Re-instantiation Stability Fix: Fixed a potential playback issue where static channel audio elements removed from the DOM during square destructions remained as detached objects on subsequent track requests. Setting chan.audio = null now ensures they are cleanly re-appended and re-instantiated in the DOM.
  • Code Cleanup: Removed the obsolete and unused legacy this.preloader block inside the Square.destroy() method.
PATCH v2.4.3
2026-07-01
  • Web Audio Latency Hint Optimization: Configured the global AudioContext with { latencyHint: 'playback' } to increase buffer safety margins, lowering CPU power draw and preventing audio stutters/crackling under heavy rendering or main-thread scrolling load.
  • Callback Leakage Prevention: Added comprehensive cleanup of onwaiting and onstalled media callbacks during channel swap and square destroy routines to avoid visual state leaks and old/interrupted playback event overlaps.
PATCH v2.4.2
2026-07-01
  • Unconditional Play-Glitch Feedback: Restored the ready-to-play visual glitch effect to trigger unconditionally whenever a track starts playing or resumes (regardless of whether it had to buffer or played instantly).
PATCH v2.4.1
2026-07-01
  • Network-Adaptive Preload Throttling: Integrated Network Information API (navigator.connection.effectiveType) to dynamically scale background concurrent preloads (3 preloads on 4G/broadband, 1 on 3G, and 0/disabled on 2G/slower connections). This preserves maximum network bandwidth for active audio streaming and avoids playback stutters on slower connections.
  • Playback Buffer Stall Watchdogs: Registered onwaiting and onstalled media event listeners on active channels to automatically show the color-coded loading spinner if network congestion stymies audio data delivery mid-song, providing accurate user feedback.
MINOR v2.3.0
2026-06-30
  • Resuming State Transition Optimization: Prevented the player from showing the loading spinner and pulsing animation (.loading-active) when a track is resumed via channel-reuse. This eliminates visual flickering during paused seeks.
8 PATCHES Patch Updates (v2.3.1 – v2.3.8)
PATCH v2.3.8
2026-07-01
  • Style Invalidation Isolation: Wrapped the ambient background layers in an isolated #bg-container element and updated property setters to modify #bg-container.style directly instead of document.documentElement.style. This limits page style recalculations on animation ticks.
  • Star-to-Square Collision Pre-filtering: Pre-filtered flung squares (state.flungSquares) once per frame, reducing nested collision evaluations inside Star.update() from O(num_stars * num_squares) to O(num_stars * num_flung_squares) (reducing check operations from 4,300 to 0 in normal states).
PATCH v2.3.7
2026-06-30
  • Render Loop HSL Parsing Optimization: Modified generateColorPalette to return numerical HSL properties (hue, sat, light), and refactored updateDOM to use them directly. This completely eliminates regex execution and string parsing inside high-frequency animation frames, reducing CPU load and garbage collection pressure.
PATCH v2.3.6
2026-06-30
  • Three-Part Cleanup Audit: Audited visualizer, layout, and Web Audio subsystems for stability.
  • Web Audio Element Swap Verification: Refactored initChannelWebAudio to track connected elements via a custom chan.connectedAudio property, preventing stale Web Audio connections and memory leaks.
PATCH v2.3.5
2026-06-30
  • Deferred Now Playing UI Transition: Postponed updating the Now Playing artist/title marquee text and playback control icon state until the audio track actually begins playing (onplaying event).
  • Dynamic Loading Spinner Color: Colored the rotating playback control loading spinner to dynamically match the border/indicator color of the target square currently loading, providing a precise visual cue of an impending change.
PATCH v2.3.4
2026-06-30
  • Playback Seek Guard: Capped the fail-safe playhead seek listener (onTimeUpdateSeek) to a maximum of 5 attempts. This prevents event-loop recursion and infinite seek-loops if a browser or local server fails to update the audio timeline, preventing browser lag/freezes.
PATCH v2.3.3
2026-06-30
  • Playback Cache Share Optimization: Reconfigured the audio engine to dynamically bind the square's already-preloaded preloadAudio element as the playback channel's active audio device. This bypasses the browser's source-changing and range-reloading phases, yielding absolute zero-latency, instantaneous playback on clicks.
PATCH v2.3.2
2026-06-30
  • Off-Screen Preloading & Pop-In Spawning UX: Delayed appending square elements to the DOM canvas container until their audio preloading is fully completed or failed. Squares now only spawn and animate into view when they are already glowing (.preloaded) and 100% ready to play instantly, removing on-screen buffering states entirely.
PATCH v2.3.1
2026-06-30
  • Playback Resuming Optimization: Restructured playhead seeking. We now prevent seeks entirely if the audio element is currently playing (e.g. fading out) when a track is clicked again, letting the audio swell back in volume instantly from its current playhead position. Seeks are applied only when a track is fully paused, eliminating dual-loading seek stutters.
MAJOR v2.1.0
2026-06-27
  • Stardust Collisions: implemented kinetic bounding box interaction between high-velocity flung visualizer squares and the background starfield particles. Collision events transfer velocity momentum and trigger transient bursts of circular white stardust sparkles.
9 PATCHES Patch Updates (v2.1.1 – v2.2.9)
PATCH v2.2.9
2026-06-30
  • Selective Preload Suspension: Modified suspendAllPreloads() to abort downloads ONLY for squares that are actively preloading (pulsing). Fully preloaded squares (glowing/ready) now retain their preloadAudio instances and cached in-memory byte buffers.
  • Preload Audio Memory Lifetime: Preloaded audio elements are kept referenced to preserve their caches, and are dynamically cleared/released inside the destroy() method when squares are shrunken or removed, preventing memory leaks.
PATCH v2.2.8
2026-06-30
  • Fail-Safe Playhead Seek Guarantee: Implemented a temporary timeupdate listener that continuously attempts to restore the playhead to the paused position. Once the media engine buffers enough data to populate seekable ranges and successfully completes the seek, the listener automatically unregisters. This resolves edge cases where browsers silently ignore seeks during metadata/loading state transitions.
PATCH v2.2.7
2026-06-30
  • Same-Origin Local Metadata Extraction: Restored metadata and album art extraction when running the site via a local dev server (e.g. localhost or 127.0.0.1), removing the isLocal bypass and the legacy external CORS proxy. Metadata extraction is now bypassed only for raw file:// protocol views.
  • Dynamic Album Art Glitch Transition: When background album art finishes loading, if the target square is currently active, it automatically swaps the background image from the fallback artist logo to the high-res MP3 cover art and triggers a visual glitch transition.
PATCH v2.2.6
2026-06-30
  • Preload Watchdog Timer: Implemented a 10-second timeout on background audio preloads. If a request hangs or is throttled by the browser, it is automatically aborted, freeing concurrent queue slots and unlocking the visualizer spawning engine.
PATCH v2.2.5
2026-06-30
  • Self-Throttling Spawning Engine: Throttles scheduling of new squares until all squares currently on the screen are playable (fully preloaded/glowing or actively playing).
  • Dynamic Spawn Interval Scaling: Automatically scales the spawning interval delay to get longer as more squares accumulate on screen using a (1 + N * 0.15) multiplier factor, reducing visual and network congestion.
  • Resilient Preloader Restoration: Blocks background queue processing during active playback buffering (loading-active) but robustly resumes queue execution on active play completion, pause transitions, natural ended completion, and loading failures.
PATCH v2.2.4
2026-06-30
  • Intelligent Audio Channel Reuse: enqueues a static channel lookup checking if the track path is already loaded. If so, it resumes playback synchronously from its paused position instead of reloading, preventing re-buffering lag.
  • Drag/Fling Neon Glow Intensity: softened the neon drop-shadow glow opacity (ratio * 0.35 instead of 0.8) and spread (max 30px instead of 55px) when flinging squares to match the dark slate ambient aesthetic.
PATCH v2.2.2
2026-06-30
  • Concurrent Background Preloader Queue: enqueues audio tracks for preloading as soon as their squares appear on screen, limited to 3 parallel downloads to prevent connection throttling.
  • Active Playback Prioritization & Suspension: instantly aborts background preloads when a square is clicked, directing 100% of bandwidth to active buffer loading, and automatically resumes background processing once playback starts.
  • Clicked Buffer Feedback: visual fast pulsing (.loading-active at 0.6s cycle) indicator state for clicked tracks while buffering.
  • Interrupted Buffering Cleanups: immediately stops buffering loads, halts fast-pulsing animations, and restores interrupted tracks to the front of the preload queue if another square is clicked during loading.
  • Playback Initiation Glitch: added a highly stylized, high-contrast hue-rotating visual glitch effect on the album artwork and visualizer square when a buffering track successfully transitions to playing state (fast-pulse stops).
  • Hybrid Local-Remote Fallback: prioritizes same-origin local range requests for sub-10ms loads, with automatic remote fallback to 1kx.org if files are missing locally.
  • Chrome GPU Compositor Viewport Clipping: refactored background layers and starfield canvas positioning to position: fixed with absolute anchors to prevent grey/brown blocks at the bottom of full-screen desktop Chrome viewports.
PATCH v2.1.2
2026-06-30
  • Fallback Logo HTML Preloading: pre-cached the three fallback logo images in the HTML head to guarantee they are immediately available on load.
  • Metadata Extraction Serialization: serialized metadata extraction via a concurrent-limited queue (max 2 parallel fetches) and reduced chunk ranges from 512KB to 128KB, eliminating network saturation on page load.
  • JS Image Preloading: deferred showing and glitching of cover artwork until the image is fully downloaded and cached in browser memory, ensuring perfect synchrony with glitch transitions.
  • Seamless Audio Node Preloader Swapping: integrated the preloaded audio elements directly into active playback channels upon clicking a square, completely bypassing buffering delay and network reconnect latencies.
PATCH v2.1.1
2026-06-30
  • Dynamic Stardust Collision Scaling: scaled particle velocity speed, size, quantity, and decay rate of collision sparkles dynamically based on the velocity of the impacting visualizer square. Slow-moving square collisions emit fewer, smaller, and shorter-lived sparkles.
MAJOR v2.0.0
2026-06-27

5 PATCHES Patch Updates (v2.0.1 – v2.0.6)
PATCH v2.0.6
2026-06-27
  • Active Tab Battery Saver: added visibility checks to pause physics and canvas particle processing when the browser tab is backgrounded, dropping background CPU overhead to 0%.
  • Starfield boundary wrap clamp: added automated star boundary correction inside the window resize event to prevent particles from drifting outside the active viewport when the window is shrunken.
  • Painting Performance Optimization: converted the dynamic center calculations for the ambient radial background gradients to bind to CSS custom variables (--bg-x and --bg-y), eliminating expensive string layout parses and style recalculations inside the animation loop.
  • Legacy dead code: cleaned up obsolete iOS Chrome user agent checks and document class additions.
PATCH v2.0.5
2026-06-27
  • Mobile Layout Bottom Offsets: adjusted bottom padding for .info-container, .song-indicator, and .dashboard on viewports <= 600px to 1rem plus the safe area inset. This matches the left/right margins exactly and prevents the floating control layout disconnect on mobile Chrome and Android browsers.
  • Cleaned up outdated static platform CSS positioning overrides.
PATCH v2.0.3
2026-06-27
  • Re-scanned and synchronized track directory /music/, updating the active track list to 252 playable entries and correcting renamed paths (such as the remastered Caseyland folders).
  • Converted newly uploaded Creme Puffs AIF demos to M4A on the server for full browser compatibility.
PATCH v2.0.2
2026-06-27
  • Audio pause fade-out resumption: saved the previous square's playback position at the *end* of the 4-second crossfade instead of the beginning, preventing audio overlapping/repeating on resume.
PATCH v2.0.1
2026-06-27
  • Setting panel grid refinement: re-arranged controls into a balanced 3x2 desktop grid and responsive mobile layout.
  • Star speed scaling: mapped the user's preferred 1.3x speed setting as the new 1.0x default (internal factor 0.26).
  • Info panel version numbering: added v2.0.1 release string inside the about menu and dashboard header.
  • Spawning placement: forced all newly created visualizer squares to initialize directly on-screen instead of sliding in from screen margins.
MAJOR v1.0.0
2026-06-22
  • Core interactive space-themed portal design.
  • HTML5 Canvas-based starfield background.
  • Floating, draggable track squares mapped to audio releases.
  • Custom retro CRT TV turn-off animations for collapsing elements.
  • Fluid ambient radial background layers.

Football 1kx.org/football

A fast-paced retro 8-bit arcade soccer game built on HTML5 2D Canvas and Web Audio synth, featuring 2.5D ball elevation physics, multi-tier shooting, teammate passing, and procedural AI attacking routines. Designed and built by Liam and Casey Cichowicz using Google Antigravity.

Game Modes & Match Formats

1kx Football features two primary modes designed for quick arcade action or continuous practice sessions:

MATCH
Competitive Match Mode

First to 5 goals wins! Play as the Pink Team against the AI Blue Team. Complete matches trigger victory celebration klaxons, match stats, and win streaks.

TRAINING
Infinite Practice Pitch

Familiarize yourself with the controls and practice your skills on an empty pitch. Tracks consecutive goal streaks (SCORE:00) and session records (BEST:00).

Match Formats & Team Size

1v1 Format
Solo Duel

Single Player vs. Single AI Opponent. Perfect for fast one-on-one dribbling duels and direct long shots.

2v1 Format
Team Play & Passing

Player 1 with an intelligent Pink AI Teammate (pinkPlayer2) against a single Blue opponent. Enables one-twos, through-balls, and switch-play.

2v2 Format
Full Team Duel

You and your Pink AI Teammate against two Blue AI players who work as a pair: one presses or attacks while the other marks your open player, covers, and runs into space — and when pressured they pass to each other. Use ← / → in the menu to cycle 1v1, 2v1 and 2v2.

Difficulty Levels

Difficulty AI Defense & Pace Shooting & Goalkeeping Behavior
EASY Relaxed marking, forgiving sprint speed Moderate shot power, basic goalkeeping reaction delay.
NORMAL Balanced positioning, active pressure Curved corner shots, dynamic goalkeeping dives.
HARD High-speed relentless pressing, tactical jukes Aggressive power strikes, deceptive baseline cuts, and rapid reflex diving.

Controls & Inputs

1kx Football supports both full keyboard controls on desktop and responsive virtual touch controls on mobile and tablet devices.

9 CONTROLS Full Game Controls & Touch Actions Table
Keyboard Key Touch / Mobile Action Category Action & Gameplay Mechanic
Arrow Keys or WASD Virtual Joystick Movement Moves your active player across the pitch. Moving into the ball dribbles it along your run path.
B (Arrows) / Y (WASD) / Hold Move SPRINT Button Movement Activates high-speed sprint burst (1.75x–2.05x speed) with upward flame particle trail and 100% ball steal immunity.
Spacebar (Tap) Standard Kick Ball Standard directional kick guided by player orientation (7.5 base force, 9.5 when sprinting).
Z (Arrows / Pinky) / P (WASD / Pinky) / Hold Space Power Shot Ball 12.0 rocket line-drive blast toward corners with golden explosion particles and POWER SHOT banner.
X (Arrows / Ring) / O (WASD / Ring) Finesse Shot Ball 8.5 precision placement strike curving in an arc into the side netting with emerald particles.
C (Arrows / Middle) / I (WASD / Middle) Chip / Lob Shot Ball 8.0 high aerial lob elevation leaping over rushing defenders and goalkeepers into the open net.
V (Arrows / Index) / U (WASD / Index) / Shift PASS Button Ball Passes the ball directly to your AI teammate, automatically leading their running stride and switching active control.
Click Scoreboard / Status Tap Status Button Menu Opens the Game Mode Selection Modal to switch between 1v1 / 2v1 / 2v2 formats and difficulty tiers.
Sound Button Tap Sound Icon Audio Toggles synthesized sound effects (whistles, kicks, goalpost strikes, crowd cheers) ON / OFF.
Mobile Floating Virtual Joystick & 1.10x Phone Zoom: On touchscreens, touching anywhere on the left half of the screen spawns a floating analog joystick for 360-degree precision dribbling. Mobile phones (<600px) render pitch and players with an optimized 1.10x zoom boost, with action button labels automatically fading out during movement to maximize pitch visibility.
Start Menu Sound FX Toggle: You can mute or unmute synthesized sound effects at any time directly within the Start Menu & Mode Select modal footer (SOUND FX) before kicking off.

2.5D Ball Elevation & Physics Model

The pitch simulation uses full 3D spatial coordinate vectors (x, y, z) for the soccer ball, combined with dynamic shadow projection to render true 2.5D arcade depth:

Elevation (Z)
True 2.5D Trajectories

Shots rise into the air and arc downward under gravity. High chips can sail completely over sliding defenders directly on target.

Shadow Depth
Dynamic Ground Shadow

An elliptical shadow tracks on the pitch directly beneath the ball. As the ball climbs in altitude, the shadow shrinks and softens proportionally.

Elastic Woodwork
Goalpost Elastic Deflections

Striking the circular goalposts or crossbar calculates realistic restitution angles with distinct synthesized metallic sound FX.

Magnus Curl
Ball Spin & Curve Shifting

Striking the ball at sharp angles imparts angular velocity, curving shots past defensive walls and into top corners.

Teammate Passing & Coordinated Play

In 2v1 and 2v2 match formats, you are paired with an intelligent Pink AI Teammate. The passing engine provides fluid tiki-taka combinations:

Leading Passes
Predictive Vector Leading

Pressing Shift or P calculates the teammate's velocity vector, playing the ball ahead of their running stride rather than behind them.

Player Switch
Instant Control Hand-Off

When the pass connects with your teammate, active user control transfers seamlessly to the receiving player without dropping momentum.

Support AI
Tactical Support Positioning

Your AI teammate actively makes overlapping wing runs, drifts into open shooting lanes, and drops back defensively when you lose possession.

Procedural AI Attacking Strategies

The AI opponent evaluates pitch geography, defensive positioning, and tackle proximity to execute distinct offensive routines:

Strategy Routine Tactical Approach Shot Execution & Behavior
CENTER_POWER Direct central charge through midfield Fires maximum velocity line drive aimed at top netting.
FLANK_OVERLAP Wide wing run along baseline Cuts sharply inward and strikes toward far post into the goal mouth.
CHIP_LOB Evaluates defender advance distance Lofts an elevated chip shot over closing defenders into the net.
ZIG_ZAG Rapid lateral step-overs (jukes) Evades sliding tackles before snapping a quick release shot.
FINESSE_CURL Diagonal box entry angle Curling banana shot around defenders into side netting.

Blue Team Play (2v2)

In the 2v2 format the two Blue players share the work. The one nearest the ball plays the routines above; the other supports — running the opposite lane and crashing the far post when Blue attack, standing goal-side of your open player when you have the ball, and covering a loose ball. A Blue player who is being closed down will pass to a teammate who has space and a clear lane, so watch the passing lanes as well as the ball.

CRT Display & 4-Second Auto-Hide Engine

Auto-Hide
4s Uncluttered Pitch View

Corner HUD labels (#status-text, sound button, and control hints) automatically fade out 4 seconds into active dribbling and passing to provide full view of the pitch.

Scoreboard
100% Persistent Scoreboard

The halfway-line scoreboards (PINK 00 : 00 BLUE) remain locked on screen at all times so you never lose track of match status.

Arcade Synth
Web Audio Sound FX

Features retro 8-bit procedural sound synthesis for ref whistles, hard kick thuds, net swishes, post clangs, and goal siren klaxons.

Release History & Changelog

MINOR v3.07.001
2026-09-20
  • 2v2 Match Format (football/js/game.js, football/index.html): A third match format alongside 1v1 and 2v1: you and the Pink AI teammate against two Blue AI players. The Blue player nearest the ball runs the existing strategy engine unchanged; the other supports (attacking run, goal-side marking, cover) and Blue players pass to each other under pressure. The Blue teammate wears #10 with the colours inverted, and the controlled-player arrow is orange. 1v1 and 2v1 are unchanged (18 seeded games hash identical to the previous build, frame for frame).
  • Tunable Blue Characteristics (BLUE_TUNING): Every Blue characteristic (speed, acceleration, tackle strength, trap chance, block radius and minimum block speed per player; pass readiness and thresholds per team) is one table, editable live from the browser console. The 2v2 teammate ships with a first-guess handicap after playtesting showed 2v2 was too strong.
  • Deterministic Replay Harness (scripts/football_sim.js): Seeded, scripted replays with --measure, --tune k=v and --fingerprint --against <game.js> to prove whether two builds play identically.
  • Possession-Latch Knob (off by default): Blue could re-roll its play 15–23 times per possession because possession is tested at a shorter distance than the ball is dribbled at. possessionReleaseDist set to 22 in the console fixes it at the cost of fewer shots per minute; it ships off so default play is unchanged.
  • Known limitation: 2v2 was confirmed for look and kickoff on desktop; touch input is not yet tested on a device. 3v3, 4v4 and 5v5 are held back.
MINOR v3.06.001
2026-09-06

2026-08-10
  • Controls/Multi-Touch: Multi-Touch Touch Identifier Separation (football/js/game.js): Assigned discrete touch identifiers (joystickTouchId and shootTouchId) to joystick and shoot button event handlers, preventing joystick touches from overriding shoot button swipe displacement calculations during simultaneous multi-touch play.
MAJOR v2.01.001

  • Conditional Corner UI Reveal on Loading Completion:
  • Updated loading completion logic in game.js to evaluate active player inputs (touch or keys pressed) upon transition.
  • If player interaction is detected during loading finish, corner UI elements remain hidden (cornerUIHidden = true); otherwise, corner UI elements smoothly fade in via .fade-out class removal.
PATCH v0.5.11
2026-07-31
  • Initial Loading Corner UI Element Transition & Visibility Fix:
  • Added .fade-out class to initial HTML elements (#status-text, #sound-btn, #control-hint, .back-link-container) to ensure seamless opacity transitions during loading screen initialization.
  • Updated state transition handler in game.js to smoothly reveal corner UI elements via CSS class removal (classList.remove('fade-out')) rather than hard inline display style toggling, eliminating visual flashes on game start.
PATCH v0.5.10

2026-07-30
  • Dribble-Kick Overwrite & Weak Shot Mechanics: Added ball.kickCooldown = 15 (15 frames / ~250ms of free ballistic flight) when pressing SPACE. Boosted kick forces (7.5 base force, 9.5 rocket shot when sprinting) and added directional aiming from WASD / Arrow keys, preventing dribble coupling from overwriting kick velocity.
PATCH v0.1.14
2026-07-30
  • Unified Mobile Full Pull & Desktop Key Hold Sprinting: Mobile full pull (joystick dragged past inner circle into outer ring) and desktop longer key hold (>1.0s) now reach the exact same 1.35x top sprint speed (2.97 units/sec), 85ms footwork rate, and retro white dust trail particle effects.
PATCH v0.1.13
2026-07-30
  • Dual-Ring Mobile Touch Joystick UI:

PATCH v0.1.11
2026-07-30
  • Desktop Running Acceleration: Holding any arrow key / WASD direction continuously for >1.0s (RUNNING_ACCEL_HOLD_TIME) triggers a 35% speed boost surge (RUNNING_ACCEL_BOOST), faster footwork animation, and sprint dust particles.
  • Mobile Proportional Touch Speed: Dragging the touch joystick knob controls player speed proportionally based on pull distance from center (gentle pull = slow precision walk, full pull = top speed).
PATCH v0.1.10
2026-07-30
  • Renamed upper-left header text from PRACTICE MODE to TRAINING MODE.
PATCH v0.1.9
2026-07-30

PATCH v0.1.6
2026-07-30
  • Expanded dribbling control capture zone (captureDist = 19.5px) when moving. This prevents losing the ball on 180° direction changes or sharp cuts, smoothly swinging the ball around to the new path while still allowing the ball to be lost if kicked far away.
PATCH v0.1.5
2026-07-30
  • Redesigned all 8 ball rotation frames to strictly use compact 2x2 and 2x1 square/plus charcoal patches (BB), eliminating long 4-pixel rectangular bars (BBBB).
PATCH v0.1.4
2026-07-30
  • Scaled down ball size to a smaller, cuter 8x8 pixel grid (radius = 4), matching player proportions.
  • Doubled ball rotation frame density to 8 distinct smooth rolling frames (ballSprites[0..7]), eliminating frame stutter when rolling.
  • Preserved the reference soft palette (#f5f2eb cream body, #a8a59e gray border contours, #363431 charcoal pentagons).
PATCH v0.1.3
2026-07-30
  • Replaced harsh black-bordered ball with a soft-contoured 12x12 pixel art soccer ball matching the reference graphic.
  • Applied off-white/cream body (#f5f2eb), subtle center hub accent (#e3dfd7), soft charcoal pentagon patches (#363431), and anti-aliased gray border contours (#a8a59e) to remove harsh black outlines.
PATCH v0.1.2
2026-07-30
  • Implemented Option A Sensible Soccer style 10x10 pixel ball design.
  • Added crisp 10x10 black pentagon patch patterns with specular gray highlights (#d0d0d0).
  • Added subtle turf drop shadow (rgba(10, 30, 10, 0.4)) rendered underneath the ball.
PATCH v0.1.1
2026-07-30
  • Softened color contrast between alternating turf stripes (#1b4e1b vs #164516).
  • Added subtle 8-bit stipple dither texture to each field band.
  • Made outer boundary lines and halfway line solid pure white (#ffffff).
  • Mathematically bounded penalty D-arcs using acos(20/35) so they start precisely at the 18-yard penalty box line without crossing inside the box.

CaseyCase 1kx.org/CaseyCase

A tool for applying title case rules and for editing MP3 metadata tags and artwork, optimized for Apple Music. Designed & built by Casey Cichowicz using Google Antigravity.

Intelligent Title Casing & Quote Normalization

The text transformation engine applies AP and Chicago style capitalization rules while automatically resolving messy quote encodings and legacy ID3 mojibake.

Grammatical Title Casing Auto Rules

Capitalizes major words while preserving lowercase for standard English minor words (a, an, the, and, but, or, for, nor, on, in, at, to, by, with, of, as, from, into, over, after, via). Always capitalizes first and last words of phrases and sub-phrases.

Acronym & Initialism Guard Preservation

Automatically detects and preserves capitalized acronyms and initialisms (e.g. DJ, EP, LP, VIP, BBC, USA, UK, ID, MC, CD, OST) without converting them to lowercase or improper casing.

Universal Quote & Apostrophe Normalizer ASCII Clean

Converts all typographic single quotes and curly apostrophes (’, ‘, ‛, ‚, ′, ´, `) to standard ASCII apostrophe ('), and curly double quotes (“, ”, „, «, ») to straight double quotes (").

CP1252 & Mojibake Decoding Byte Repair

Decodes byte-level Windows-1252 control codes (\u0091, \u0092, \u0093, \u0094, \u0096), HTML entities (&apos;, &#39;, &rsquo;), and garbled UTF-8 mojibake (’, ‘, “).

Live Conversion & Clipboard Sync: Toggling the live conversion switch processes text in real-time as you type, and single-click copying uses the secure asynchronous Clipboard API (navigator.clipboard.writeText) with an ephemeral in-memory history log.

Single & Multi-Track Audio ID3 Tag Editor

Comprehensive ID3v1, ID3v2.3, and ID3v2.4 frame manipulation directly in the browser via binary byte decoding and serialization.

8 ID3 FRAMES ID3 Frame Specs & Automation Routines Table
ID3 Frame Standard Field Name Automation & Processing Routine
TIT2 Track Title Automated track prefix stripping (08 - Song Title → Song Title), smart capitalization, and quote normalization.
TPE1 Lead Performer / Artist Hyphenated artist-title auto-splitting (Artist - Title) and typography normalization.
TPE2 Album Artist Multi-track consistency management. Automatically sets Various Artists for compilations.
TALB Album Title Batch album assignment across multi-file drag-and-drop queues.
TRCK / TPOS Track & Disc Number Sequential numbering auto-increment and prefix extraction from filenames.
TCMP Compilation Flag iTunes / Apple Music compilation flag byte (0 or 1).
TSOP / TSO2 Sort Artist / Album Artist Inverted article sorting (e.g. The Weeknd → Weeknd, The; A Tribe Called Quest → Tribe Called Quest, A).
APIC Attached Picture (Artwork) Binary cover art extraction, replacement, and 1:1 canvas square cropping.
Singles Mode Smart Sync Single Track

When a single MP3 is loaded, the Track Title automatically populates the Album Title (with feature annotations like feat. ... or ft. ... intelligently stripped for the album tag), syncs the Album Artist to the primary Artist, defaults the Grouping tag to Single, and leaves the Disc Number empty to eliminate unnecessary 1/1 tag clutter on media players.

Album & Multi-Track Batch Workflow Album Mode

Loading multiple tracks or an entire album folder creates a unified batch queue with structured table columns (Track #, Title, Artist, Album, Year, Filename). Global Album Title and Album Artist apply uniformly across all tracks, interactive drag-and-drop row reordering automatically renumbers tracks sequentially (1 to N), and multi-disc albums default empty disc tags to 1 only when multiple discs exist.

Automated Junk Phrase & Video Stripper Auto Clean

On file import, CaseyCase automatically identifies and strips unwanted promotional clutter and video tags from titles and filenames, including (Official Music Video), (Official Lyric Video), (Official Visualizer), (Official Audio), (Visualizer), (Audio), Vevo, and Topic inside parentheses, brackets, or standalone text.

Hyphenated Artist-Title & Track Parsing Auto Parsing

Automatically detects and splits Artist - Title filename patterns into discrete Artist and Track Title tags. It also extracts leading numerical prefixes (e.g. 08 - Song Title → Track 8, Title Song Title) and strips redundant artist prefixes from titles matching the primary artist.

Album Artwork Processing & 1:1 Canvas Square Cropping

Ensures album artwork displays without letterboxing or distortion on automotive dashboards (Apple CarPlay, Android Auto), mobile lock screens, and media players.

Offscreen 1:1 Canvas Cropping Canvas 2D

Non-square images are automatically centered and cropped to 1:1 square dimensions on an offscreen HTML5 canvas before embedding into the binary MP3 APIC frame.

High-Resolution Cover Search 1500x1500px

Integrated album artwork lookup dialog communicating with secure online repositories to fetch pristine 1500x1500px high-definition cover art directly into the tag queue.

Export Pipeline, ZIP Bundling & Privacy Architecture

Export modified tracks individually with clean standardized filenames or package entire albums into structured ZIP archives.

100% In-Browser Privacy Zero Uploads

All binary audio operations, ID3 serialization, pixel crops, and text conversions execute exclusively within the client browser. No audio or metadata is ever transmitted over the network.

JSZip Multi-Track Packaging ZIP Archive

Batch export entire multi-disc albums into a single structured ZIP archive maintaining track numbering and standardized 01 Track Title.mp3 (or 1-01 Track Title.mp3 for multi-disc) naming conventions with empty grouping tags.

Memory Lifecycle Hygiene Auto Revoke

Ephemeral object URLs generated for audio preview playback and album art blobs are systematically released via URL.revokeObjectURL to prevent heap memory growth.

Service Worker Audio Streaming HTTP 206

A lightweight service worker (sw.js) intercepts audio playback requests and serves 206 Partial Content byte ranges for instant waveform scrubbing without loading entire files into memory.

Release History & Changelog

MINOR v2.06.001
2026-09-09
  • Audio Import Pipeline (CaseyCase/index.html, CaseyCase/js/app.js): Added an optional companion-server import path that fetches audio from a URL, transcodes to 320 kbps CBR MP3, and writes Apple-Music-oriented ID3v2.3 tags including embedded cover art, with promotional suffixes stripped from artist and title.
  • Import Reliability Fix: Resolved failures caused by the companion server resolving an out-of-date extraction tool. It now selects the newest available version rather than the first on the path, reports a stale install with the command that fixes it, and surfaces only the relevant error lines. 67 regression assertions passing.
  • Metadata Pipeline Consolidation (CaseyCase/js/app.js): Single-file and album export previously built the same ID3v2/ID3v1/artwork tag set independently in two places that had already drifted. Unified into one function both paths call, parameterized only by the values that genuinely differ.
  • Artwork Lookup Timeout (CaseyCase/js/app.js): A stalled iTunes artwork lookup previously spun its loading indicator forever with no way to recover. Now times out and cleans up automatically.
  • Real Offline Support (CaseyCase/sw.js): CaseyCase is installable, but its service worker had never actually taken effect — it registered with no explicit scope, which defaults to the directory of the script file rather than the page, so it never controlled the app and never cached anything for offline use. Moved to the app root and rebuilt to precache the app shell, so an installed copy now genuinely opens and runs with no connection.
8 PATCHES Patch Updates (v2.06.002 – v2.06.009)
PATCH v2.06.009
2026-09-25
  • Companion Server YouTube Import Disk Copy Fix (CaseyCase/scripts/yt_single.py): Suppresses redundant duplicate MP3 file copies to ~/Downloads in companion server mode, streaming bytes directly to the browser so the user chooses the save destination via the Download button.
PATCH v2.06.008
2026-09-12
  • Title-Enclosing Quote Stripper: Automatically strips enclosing single/double quotes wrapping entire song titles while preserving internal quotes and contractions.
  • Single vs. Album Disc Grouping: Enforces "Single" grouping on singles and empty grouping on album tracks with standardized ZIP track filenames.
  • m4a Cover Art & Field Reset: Resolved m4a APIC cover art rendering and reset media input status upon track upload.
PATCH v2.06.007
2026-09-10
  • Companion Extraction Tool Install Guidance Fixed for Intel Macs (CaseyCase/scripts/install_yt_companion.sh): Confirmed on real hardware that Homebrew now refuses to install media extraction tools on Intel Macs ("We do not provide support for this platform"), while ffmpeg still installs fine there via a cached bottle. The installer now routes tools through uv instead, an architecture-independent tool unaffected by Homebrew's platform policy.
PATCH v2.06.006
2026-09-10
  • Companion Installer Guides Through Xcode CLT & Homebrew (CaseyCase/scripts/install_yt_companion.sh): Testing the setup zip on a second Mac with no developer tools or Homebrew surfaced two unexplained first-run obstacles. The installer now detects both up front and prints the exact fix instead of leaving someone stuck on a bare missing-command error.
PATCH v2.06.005
2026-09-10
  • Companion-Server Setup Download (CaseyCase/js/app.js, CaseyCase/scripts/deploy.py): The "companion server not running" error now links to a downloadable caseycase-companion-server.zip (the server script, its installer, and a README) for setting the companion server up on a different Mac, rebuilt fresh from source on every deploy so it can never drift out of sync.
PATCH v2.06.004
2026-09-10
  • Local Network Access Enum Fix (CaseyCase/js/app.js): Chrome's Local Network Access address spaces distinguish loopback (localhost) from local/private (other LAN addresses); the fetch calls used the wrong value and were rejected outright. Corrected to targetAddressSpace: 'loopback'.
PATCH v2.06.003
2026-09-10
  • Companion Server Unreachable From the Live Site (CaseyCase/js/app.js): Testing from the deployed site against a localhost companion server hit Chrome's Local Network Access policy, which silently blocks a public HTTPS page from reaching localhost unless the fetch itself opts in. Added the required targetAddressSpace fetch option.
PATCH v2.06.002
2026-09-10
  • Always-On Companion Server Install Script (CaseyCase/scripts/install_yt_companion.sh): Installs a macOS launchd service for the companion server that starts at login and restarts itself if it ever quits, checks for required dependencies up front, and detects a macOS-specific permission failure (background processes under ~/Documents need Full Disk Access) rather than leaving it looking like a bug.
  • 1kx Unlock Sequence Leaking Into URL Field (CaseyCase/js/app.js): Typing the unlock sequence left a stray character in the newly-revealed URL field because focus moved there before the browser finished inserting that keystroke. Fixed with preventDefault().
  • Companion Server Reporting "Not Running" While Alive (CaseyCase/scripts/yt_single.py): The server handled one connection at a time, so any slow or stuck request blocked the health check the browser relies on. Switched to a threaded server with a per-request timeout.

Quick Start & Flight Fundamentals

SimPlane runs directly inside any modern web browser without downloads, plug-ins, or compilation steps. Follow this six-step walkthrough to configure your aircraft, execute a textbook runway takeoff, pilot through the procedural terrain, and grease your touchdown on Runway 18.

STEP 01
Select & Inspect Your Airframe

Launch into Plane Selection / Showcase Mode 1. Browse the 15 authentic fleet models using the top-docked carousel or P to cycle aircraft. Engage turntable auto-rotation T, inspect mechanical subsystems with component hotspot buttons, or toggle the cargo visor door / supersonic droop nose V on heavy transports and Concorde.

STEP 02
Line Up on Runway 18/36

Switch to Runway Lineup Mode 2 to place your aircraft on active Runway 18. Release the parking brake with . (hold Space to brake), set takeoff flaps to 15° with F, and test ground steering using the rudder pedals Q / E or aileron steer keys A / D.

STEP 03
Throttle Advance & Acceleration Roll

Hold Shift to advance the engine throttle to 100%. High-bypass turbofan engines follow authentic spool-up inertia lag (1.8s time constant). The roll takes as long as the real aircraft's: about 30–50 seconds and 1–2 km for an airliner, under 20 seconds for the X-59. Maintain runway centerline alignment during the acceleration roll using differential rudder steering taps.

STEP 04
Rotation Flare & Positive Climb

When airspeed accelerates past rotation velocity V_R (announced by avionics chime tones and HUD cue), pull back gently on the flight stick with S or down arrow. Establish an 8° to 10° climb pitch attitude, and retract landing gear with G upon positive rate of climb.

STEP 05
Airborne Navigation & Terrain Recon

Enter In-Flight Mode 3 for free 3-axis aerodynamic flight. Bank into coordinated turns with A / D, explore the 20km procedural terrain, alpine peaks, and river valleys, or engage the Autopilot Master with Z for altitude and wings-level cruising.

STEP 06
Glideslope Approach & Touchdown

Align with Runway 18 on a 3° descent path using the 4-light PAPI visual guidance system (2W2R indicates on-slope). Deploy flaps with F and landing gear with G. Slow down early: with the power off, an airliner loses only 1–3 knots a second. Flare over the threshold and touch down with wheel smoke; with the Landing Assist on (Flight Settings), the throttle comes back to idle as the wheels touch. Then engage reverse thrust with B and apply wheel brakes with Space.

Operational Modes & Camera Perspectives

SimPlane features three dedicated simulation modes and four modular camera perspectives designed for pre-flight mechanical inspection, precision runway operations, and full 3-axis aerobatic flight dynamics:

MODE 1
Plane Selection & Showcase Hangar

An interactive 3D showroom mounted on a circular reflective turntable platform. Features concentric distance guide rings at 100ft, 200ft, 300ft, and 400ft for visual scale comparison, component hotspot inspection cameras (Cockpit, Engines, Tail, Gear, Cargo Visor), and full technical specification dialogs.

MODE 2
Runway 18/36 Lineup & Ground Ops

Active runway threshold alignment with approach lighting systems, parallel taxiway turnoffs, Antonov barrel-vault hangars, and a 55m Air Traffic Control tower with a rotating beacon. Supports manual throttle spooling, ground nosewheel steering, and an automated one-click takeoff sequence button.

MODE 3
In-Flight Free Aerodynamic Flight

Unrestricted 3-axis flight across procedural mountain ranges, patchwork agricultural valleys, and river networks. Includes dynamic airspeed tape, stall recovery physics, over-speed aerodynamic buffeting, and an automated glideslope landing sequence button.

CAMERAS
3 Camera Perspectives

Switch camera viewpoints instantly with C: Dynamic Chase (speed-scaled trailing anchor behind empennage with coordinated roll lag), Orbit / Turntable (360° touch/mouse orbital inspection) and Overhead (looking down on the aircraft from a few hundred metres, nose up the screen; scroll or pinch to raise or lower it, for the terrain).

Master Key Commands & Touch Controls

SimPlane supports full dual-mode keyboard controls alongside responsive on-screen mobile virtual touch controls. Every flight control is mapped to standard ergonomic keybindings:

Mobile Virtual Touch Controls

On touchscreen devices or whenever activated via H, SimPlane presents dual ergonomic virtual quadrants:

  • Virtual Flight Stick Quadrant: Located on the lower-left, featuring spring-to-center physics providing proportional 2-axis pitch and roll deflection. Let go and the aircraft keeps the bank and pitch you left it in; light LVL to have the wings come level by themselves.
  • Progressive Throttle Slider Quadrant: Located on the lower-right, featuring continuous 0% to 100% thrust adjustment with visual N1 spool indicators.
  • Quick-Action HUD Bar: Touch-friendly tactile buttons for Flaps, Gear, Camera, Brakes, and Autopilot positioned along the viewport margins.

Avionics HUD & Flight Mode Annunciation (FMA)

SimPlane provides two selectable HUD presentation formats (toggle with U) with comprehensive autopilot state annunciations:

  • Top-Bar Autopilot HUD Buttons: Interactive cluster with clickable status buttons for AP (Master Autopilot, hotkey Z), LVL (Wing Leveler), ALT (Altitude Hold), and HDG (Heading Hold). Active modes illuminate with vivid green avionics glow.
  • Traditional Flight Mode Annunciator (FMA): When using the traditional collimated flight HUD, a top FMA status bracket displays active guidance modes across three channels: Speed (MCP SPD or MANUAL), Lateral (HDG SEL, LVL HOLD, or ROLL HOLD with no lateral mode; LVL while the wing leveler works without the master), and Vertical (ALT HOLD or G/S), alongside a master AP / FD annunciator box.
  • Flight Director Guidance Overlay: Dynamic horizontal pitch bar and rotating roll bar provide precision steering cues to satisfy active target heading and target altitude bugs.
  • Pilot Safety Override: Applying manual pitch or roll stick input greater than 25% deflection immediately disengages autopilot master control to ensure instantaneous pilot takeover. LVL stays lit: it only pauses while you steer.

Aerodynamic Physics & Flight Dynamics

SimPlane implements a deterministic flight simulation engine delivering continuous aerodynamic flight physics without external physics libraries:

AERODYNAMICS
Continuous 3-Axis Physics

Calculates dynamic lift, drag, and thrust vectors per frame. Coordinated turn kinematics automatically couple roll angle with yaw rate (Δψ = +sin(θ_z) × 0.85 × Δt), eliminating slip/skid tendencies during steep banks.

SPOOL INERTIA
Turbofan N1 Spool Dynamics

Engines do not respond instantly to throttle commands. Core rotational spooling follows an asymptotic lag curve with a 1.8-second acceleration time constant (τ_spool = 1.8s). Effective thrust scales quadratically with N1 rotational speed.

GROUND EFFECT
Aerodynamic Vortex Cushion

Flying within one wingspan of the ground plane traps trailing wingtip vortices, reducing induced drag by up to 35% and boosting lift by 15%. This provides an authentic aerodynamic cushion during the final landing flare.

V-SPEEDS
Dynamic Avionics Annunciations

Calculates takeoff decision speeds (V_1), rotation velocity (V_R), and safety climb speed (V_2) derived from airframe mass and flap setting, announced with dual-tone audio chimes and HUD cue banners.

GUIDANCE
PAPI & ILS Glideslope Array

Runway 18 features a calibrated 4-light Precision Approach Path Indicator array calibrated for a standard 3.0° descent slope (4W high, 2W2R on-slope, 4R low) paired with cockpit ILS crosshairs.

BRAKING
Thrust Reversers & Heavy Brakes

Wheel brakes Space stop an airliner from touchdown in about 15–20 seconds and 500 m. Thrust reversers B add to them: a little at idle, more as you add throttle. They stow by themselves at 20 knots with the throttle back at idle. With neither, idle thrust and the ground spoilers alone take about a minute and most of the runway.

AVIONICS
Autopilot & Flight Director Suite

Toggle master autopilot with Z or the top-bar HUD button (AP). Supports three automated sub-modes: Wing Leveler (LVL, hotkey Y, off at the start) brings the wings level whenever you let go of the stick, and works on its own without the master; with it off, the aircraft keeps whatever bank you leave it in; Altitude Hold (ALT / ALT HOLD) holding target altitude AGL (default 1,500 ft) via proportional elevator commands; and Heading Hold (HDG / HDG SEL) executing coordinated turns up to ±25° bank. Moving pitch or roll controls beyond 25% deflection triggers an instant manual safety override. In addition, collimated Flight Director crossbars (FD) provide dynamic pitch and roll steering cues. The nose stays where you put it: under power, a climb trades speed for height, so level off before the speed runs out.

1kx Terrain Procedural Engine

SimPlane features the in-house procedural 1kx Terrain engine, shared with the root visualizer's Earth Observation system. The world generates concentric LOD terrain rings directly on the GPU without streaming external satellite imagery:

GPU PIPELINE
GPU WebGL Texture Baking

Multi-stage WebGL fragment compute shaders pipeline heightmaps, normal gradients, and landcover masks directly into GPU textures with persistent buffer recycling, eliminating frame budget latency spikes.

EPHEMERIS & SEASONS
Sun, Moon, Planets, Stars & Seasonal Terrain

The celestial dome and landscape dynamically reflect the time of day and calendar season: the sun and moon follow astronomical orbits with real lunar phases, 4 Keplerian planets and 5,044 catalog stars map the night sky, while ground lighting, street lamps, city window glow, tree foliage colors, and mountain snowlines shift continuously with the clock and season.

HYDROLOGY
Hairline River Sources & Shorelines

River networks emerge as sub-metre threads inside wooded hollows and mountain ravines. Narrowing V-notch valley floors ensure water stays inside its bed, while steep-slope gating eliminates unnatural water on slopes over 35°.

ROADS & BRIDGES
3D Ribbon Networks & Lamp Posts

Rural highways and section roads are modeled as real 3D ribbon meshes that follow natural terrain grades, complete with straightened bridge spans over rivers and roadside lamp posts spaced every 36m.

SETTLEMENTS
Procedural Cities & Night Glow

World-keyed city lattices place low-rise residential and commercial buildings with gabled roofs and window bays. At night, lit windows cast warm radial light spills onto streets and surrounding yards.

FLORA & FORESTS
8 Tree Species & Procedural Canopy

Eight authentic tree models (birch, willow, spruce, pine, oak, columnar, shrubs) placed from landcover masks with distinct canopy geometries, species-specific height profiles, and procedural forest distribution across biomes.

METEOROLOGY
Dynamic In-Flight Weather System

Continuous aerodynamic atmospheric timeline modeling barometric pressure lapse rate, dynamic wind vectors, gust turbulence, rain streaks, snow flakes, localized fog banks, and synchronized lightning flashes with acoustic thunder roll.

ATMOSPHERE
Volumetric Clouds & Solar Shadows

Multi-layered procedural cloud systems featuring billowy puff meshes, ground-projected cloud shadows matching the astronomical sun vector, high-altitude cirrus veil, and smooth in-cloud fogging transitions upon penetration.

Aircraft Fleet Registry & Specifications

Every aircraft in SimPlane is modeled with standardized aeronautical specifications, capturing authentic airframe dimensions, operational mass, rated engine thrust, flight envelopes, and landing gear kinematics across the 15 fleet models:

  • Manual Stick Attitude Hold Dynamics: Pitch and bank hold exactly where the stick leaves them hands-off, eliminating artificial auto-centering.
  • Independent Wing Leveler (LVL): Toggleable with Y without the AP master; pauses while steering and levels wings upon release.
  • Climb Airspeed Physics: Climbing under power realistically bleeds airspeed proportional to climb angle.
MINOR v1.03.001

  • Terrain & Hydrology Realism: Gully farm shader, living sea wave speeds & wind streaks, shore margins, deltas, waterfalls, sports fields, and landmarks.
  • Ride-Along Camera: Interactive camera seat on SimPlane's cars and river barges.
MINOR v0.13.000
2026-09-30
  • Fewer Rivers: Dry Washes: Only channels whose catchment can keep water all year carry it; the rest are dry sand-and-gravel washes in the same valleys, with no waterfalls or deltas, and roads ford them.
  • Streams Follow the Seasons: Small streams and some waterfalls run only with the spring melt and are dry by late summer; channels that never run are grassy, wooded, stony or sandy swales, and snow lies on them in winter.
  • Streams Start Thin: Every stream emerges as a thread where its water starts and widens over ~400 m.
  • HUD Toggle Pinned; Spotter Camera Retired: The HUD-style toggle sits in the pinned top-right bar and the telemetry bar's HUD/BAR switch is gone (U still switches it); C alternates Orbit and Chase.
  • Map Button Carries Time and Season: SimPlane's map button passes the clock hour and day to the Sim view.
MINOR v0.12.000
2026-09-30
  • Rivers End Like Rivers: Gorges and flat backwaters carry big rivers to the sea at sea level; every mouth swells into a rounded funnel, and the biggest rivers build marsh-and-mudflat deltas with meandering channels and silt plumes.
  • Natural Shorelines: Wet-soil margins, beaches on gentle shores, rocky cliff edges, reed marsh with standing pools, and pale sandy shallows offshore.
  • A Sea That Reads as Water: Fresnel sky reflection toward the horizon, a broken sun-glitter path, and wind streaks — dark from straight above like real satellite imagery, with zero added shimmer.
  • Rivers & Fields Interlock: Riparian woodland sized by each stream, fields ending at fences and buffer strips, meadows, shelterbelts, farmstead woodlots, ragged clearing edges, and woods in canopy clumps with glades.
  • Flora Stands on the Ground: Trees, rocks and buildings sit on the drawn terrain with tilt, settle, contact shadows and a ground grain — no more floating.
  • Aircraft Shadow: The sun's shadow follows the aircraft everywhere, crisp at touchdown and softening with height.
  • A World With Life In It: Sailboats, barges and cargo ships with wakes; cars and trucks on the roads; soccer pitches; churches, mosques, hospitals, water towers, grain elevators and lighthouses.
  • Cockpit & Navigation: Collimated HUD with roller tapes, Washington Dulles (IAD) airport, smooth keyboard ramping, go-to dialog and map round trips.
MINOR v0.11.001
2026-09-27
  • Alpine Mountain Ranges & Snow Caps: Procedural alpine relief, craggy ridges, snowline coverage, talus slopes, and distant mountain backdrops extending terrain past 10 km.
  • Sky & Terrain Settings Tabs & Celestial Tracking: Astronomical ephemeris for true sun, moon phases, Yale star catalog (5,044 stars), Milky Way, 4 Keplerian planets, shooting stars, and seasonal meteor showers.
  • Banded Chunk Painting (Zero Stutter): Multi-frame banded chunk baking with cached roof masks eliminating frame stutters.
  • Swirled River Mouth Sediment Plumes: Flow-advected silt plumes and continuous thalweg transitions across river confluences.
  • Night Road & Highway Lighting: Street and highway illumination, lit building windows, and headlight glow synchronized with the simulated hour.
1 PATCH Patch Updates (v0.11.002)
PATCH v0.11.002
2026-09-27
  • Mobile Orientation & Viewport Resize Engine: Instantaneous 3D camera projection, aspect ratio, and buffer resolution adaptation on mobile screen rotations without letterboxing or stretch.
  • Mobile Telemetry HUD De-Cluttering: Streamlined top telemetry bar on mobile screens by hiding secondary mechanical indicators (throttle, gear, flaps) while retaining airspeed, altitude, and brakes.
MINOR v0.10.001
2026-09-26
  • 1kx Terrain 1.7 Hydrology & Water Bed Alignment: River heads taper to sub-metre sources in wooded hollows. Channel beds and water surfaces share consistent width thresholds, eliminating bank-climbing at bends. Wide rivers and lake shorelines transition to smooth distance curves, eliminating staircase edges. River rendering smoothly fades out on steep cliff faces exceeding 35°.
  • 3D City Grid Geometry & Road Cleanup: City streets generate as true 3D ribbons following the urban street grid, complete with residential building layouts with yards and parks. Closed dirt-track gaps, prevented underwater road routing, and aligned bridge deck lanes.
  • Terrain Generation Retention: Landscape features are smoothly preserved where terrain elevation is stable during real-time generation, eliminating visual re-flashing across near landscape tiles.
