GIF Matrix

GIF Matrix is a pixel-grid performance visual in BeamTracer Audio Visualizers, built on WebGL. Settings, audio modulation, presets, and tips.

Default demo track · live audio-reactive settings

GIF Matrix is a pixel-grid performance visual in the Matrix LED category. Open it from the left visualizer list, start an audio source, and use the settings panel to shape its response.

Open GIF Matrix

Launch the visualizer with its matching left-nav entry selected.

Quick start

  1. Start the demo track, choose a local audio file, or enable a live input.
  2. Try a preset or style first, then open the section for the part of the image you want to change.
  3. On a control with Assign modulation, open the source picker, choose a signal, and watch the slider's live fill.
  4. Use Reset to Defaults whenever you want to return to the original look.

Audio modulation

On a control with Assign modulation, select the activity icon to open Modulate with. Choose a named source, or choose — None to leave the control unmodulated. After you assign one, its name appears below the slider; select that name to edit the route, or use Clear modulation to remove it. The slider track shows the live signal reaching the control.

The FACE preset is animated in both helmet cores. Helmet 1 shows a compact yellow smiley with an occasional double blink and a beat-synced blink. Helmet 2 keeps the eyes and grin smooth, pulses the field, and opens the grin slightly on the beat.

The NOISE preset is a fast red, green, and cream TV-static field. Louder passages raise the density of lit cells.

Helmet displays

  • DISCOVERY gives Helmet 1 a full-width red program waveform and Helmet 2 rainbow rails, a scanner, a chin VU, and heartbeat accents. Bass changes scanner speed, volume fills the chin meter, treble lights the rails, and beats reverse or fire the display.
  • BIT CHASE accelerates with bass, reverses and enters a power state on beats, and adds sparks with high frequencies.
  • SIGNAL gives Helmet 1 a volume-reactive glow bar and scan highlight. Helmet 2 combines a beat-pulsed glyph, scrolling chevrons, a three-band EQ strip, and a rainbow rail.
  • Existing presets keep their musical roles: beats trigger blinks, winks, direction changes, and lub-dub states; continuous levels change trail length, eye cadence, pulse geometry, brightness, and speed.

Arcade

The ARCADE core contains eight games: a dot-eating maze chase, a descending enemy grid, a ladder-and-barrel climb, paddle-and-bricks, a falling-block stacker, a scrolling-gap flyer, missile defense, and a side-scrolling rescue game. All eight fill the panel and respond to Speed, Hue Shift, and Beat Reactions.

Every game auto-plays by default — bass, beats, and the live 16-band spectrum drive the AI. Holding an arrow key overrides just that axis with direct control; the other axis (and auto-fire, where relevant) keeps running. Release the key and auto-play resumes.

A shared VU BACKGROUND adds faded classic-EQ bars, while VU MASK SHAPES reveals the spectrum through the game shapes. See the settings table above for which toggle applies to each game. SHOW SCORE displays a running score at the top left.

GameWhat it doesAudio responseArrow keys
MAZE CHASERA chaser follows a dot-filled path while a pursuer trails behind. The dots return after a completed lap. With VU MASK SHAPES on, the dots reveal peaks from the live spectrum.Bass speeds up the chase; beats reverse direction; the mouth and mask follow the mix.Left/Right drive the chaser directly.
GRID INVASIONA grid of spectrum bars marches across the panel while a defender fires upward. A new wave appears after the grid is cleared or reaches the bottom.Bar heights follow the spectrum; bass speeds up the march; beats fire.Left/Right drive the defender; auto-fire stays on.
BARREL CLIMBA climber ascends platforms while barrels roll downward. Each platform glows as a separate VU band.Bass drops barrels, treble speeds them up, and each floor follows its spectrum band.Up/Down step the climber directly.
BRICK BREAKA ball bounces between a sweeping paddle and a four-row brick wall (starts below the score readout so the two never overlap), clearing bricks on contact; the wall respawns once fully cleared.Bass speeds up the ball; volume drives the paddle's auto-sweep.Left/Right drive the paddle directly.
STACK FALLFalling four-cell blocks drop into a 10-column well. Completed rows clear, and a four-row clear triggers a full-board shockwave.Bass speeds up the drop; volume brightens the piece; VU MASK SHAPES reveals the live spectrum inside the blocks.Left/Right move the piece, Up rotates, Down soft-drops.
GAP FLYERA flyer passes through scrolling gaps. Missing a gap recenters the flyer and resets the score.The walls follow the spectrum; bass strengthens each flap; treble speeds the scroll.Up flaps directly.
SILO DEFENSEMissiles descend toward a row of cities while the turret launches interceptors. Direct hits and blast hits trigger expanding explosions, and the defense line doubles as a VU meter.City glow follows the spectrum; bass affects the action speed.Left/Right drive the turret directly; auto-fire stays on.
SKY RESCUEA ship patrols vertically, auto-firing at the nearest threat; landers drift in and try to lift a humanoid off the ground row. Shooting a laden lander frees its humanoid back to the ground; a lander that escapes off the top with its humanoid still aboard becomes a faster homing mutant.Enemy spawn rate and color track bass/spectrum; ship auto-tracking speed responds to treble.Up/Down drive the ship directly; auto-fire stays on.

Tips for a better audio visualization

  • Use bass for large fills or zoom and highs for small pixel detail; this reads clearly even on a distant screen.
  • Try assigning Bass to Speed, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
