Biojelly
Biojelly is an organic animated scene in BeamTracer Audio Visualizers, built on WebGPU. Settings, audio modulation, presets, and tips.
Biojelly is an organic animated scene in the Organic category. Open it from the left visualizer list, start an audio source, and use the settings panel to shape its response.
Open Biojelly
Launch the visualizer with its matching left-nav entry selected.
Call the jellyfish with your hand
In this example, Hand is set to Draw Path: a pointing finger draws the line and this visualizer moves along it. Use the playback controls to pause or replay the motion.
- Switch to Performer, pick BioJelly, and put your camera under it: open the FX Rack, add Visual Source, choose your camera and set its Visualizer to Over.
- Open Hand Tracking and leave Hand on Follow. Raise a hand and open it: the jellyfish nearby turn and swim to it, more of them the wider you open your hand, while the view holds still. Close your hand into a fist and they drift off on their own again.
- Scatter makes any hand in view drive the nearby jellyfish away.
Set Hand to Draw Path, then point with one finger and trace a loop in the air (or drag one with the mouse). A dotted line shows what you drew, then the jellyfish nearby swim it in procession until Path Life runs out. Hold up an open palm for a moment, or double-click, to clear it.
Quick start
- Start the demo track, choose a local audio file, or enable a live input.
- Try a preset or style first, then open the section for the part of the image you want to change.
- On a control with Assign modulation, open the source picker, choose a signal, and watch the slider's live fill.
- 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.
| Modulated control | Section | What the route changes |
|---|---|---|
| Bloom Strength | Glow | Sets the resting bloom strength. An assigned source lifts the live bloom from this base without changing the slider. |
| Pulse Amplitude | Animation | Controls the distance of the motion from its resting position. |
| Flow Speed | Animation | Sets how quickly flow changes or moves. |
| Luminescence | Animation | Sets how much high-frequency sound brightens the jellyfish glow; at 0 the glow ignores the treble, and higher values make it flare with the highs. |
Settings reference
Core
| Setting | Available values | What it changes |
|---|---|---|
| Jellyfish Count | 1–160 | Sets how many visible elements are drawn. |
| Time Scale | 0.25–2 | Sets the visual time scale. |
| Resolution Scale | 0.3–1 | Trades visual detail against performance. |
Body
| Setting | Available values | What it changes |
|---|---|---|
| Body Opacity | 0–1 | Sets how transparent the body appears. |
| Flesh Density | 0–1 | Controls how concentrated the visible elements appear. |
| Swim Stroke | 0–2 | Sets how strongly the bell rim cinches in and sweeps downward on each swimming pulse; at 0 the bell only pulses gently, and higher values give a pronounced, rolling swim stroke. |
Audio Glow
| Setting | Available values | What it changes |
|---|---|---|
| Audio Glow Mode | BELL ZONES — crown←bass, sides←mids, tips←treble, VU SWEEP — light slides down the tentacles, BASS PULSE — bell flashes with bass, BAND SPLIT — bass bell / mid arms / treble tips, SPECTRUM HUE — glow hue follows the spectrum, BEAT RIPPLE — ring races down on each beat | Chooses the audio glow mode or style. |
| Glow Reactivity | 0x–3x | Sets the visible strength of glow reactivity. |
Glow
| Setting | Available values | What it changes |
|---|---|---|
| Bloom Strength | 0–2 | Sets the resting bloom strength. An assigned source lifts the live bloom from this base without changing the slider. Use Assign modulation to choose a source. |
| Bloom Radius | 0–1 | Sets the visible bloom radius. |
| Bloom Threshold | 0–1 | Sets the level that must be crossed before bloom appears. |
| Inner Glow | 0–1 | Sets the visible strength of inner glow. |
Colors
| Setting | Available values | What it changes |
|---|---|---|
| Accent 1 | Color | Sets the accent 1. |
| Accent 2 | Color | Sets the accent 2. |
| Water 1 | Color | Sets the water 1. |
| Water 2 | Color | Sets the water 2. |
| Bell Tint | Color | Sets the bell tint. |
| Color Cycle | 0–3 | Sets how fast the glow and water colors slowly blend between their two chosen colors; at 0 the colors stay fixed. |
Audio
| Setting | Available values | What it changes |
|---|---|---|
| Master Gain | 0x–3x | Sets how strongly the input signal affects master. |
| Bass Intensity | 0x–3x | Sets the visible bass intensity. |
| Mid Intensity | 0x–3x | Sets the visible mid intensity. |
| High Intensity | 0x–3x | Sets the visible high intensity. |
| Smoothing | 0–0.99 | Balances immediate audio response against steadier motion. |
Hand Tracking
| Setting | Available values | What it changes |
|---|---|---|
| Hand | FOLLOW, SCATTER, DRAW PATH, OFF | In Performer with your camera on, FOLLOW draws the jellyfish to your hand, SCATTER makes them flee, and DRAW PATH lets you point and draw a curve in the air (or drag with the mouse) for the jellyfish to swim along; with no hand in view they drift on their own. With FOLLOW, open your hand to call the jellyfish nearby; close it and they drift off again. |
| Hand Strength | 0–3 | How hard your hand, or the drawn path, pulls or pushes the jellyfish. |
| Hand Depth | 0–3 | How far the jellyfish move toward you or away as you hold your hand nearer the camera than your face, or farther back; with DRAW PATH, how deep the drawn curve runs. 0 keeps the jellyfish on one plane. |
| Path Speed | 0–1 | How fast the jellyfish swim along the drawn path. |
| Path Life | 2–30 | How long a drawn stroke stays before it fades; holding up an open palm for a moment clears it. |
| Show Path | ON, OFF | Draws the path itself as a trail of dots while you draw it, larger where it comes toward you, then fades it out as the jellyfish take it over. |
Animation
| Setting | Available values | What it changes |
|---|---|---|
| Pulse Amplitude | 0–2 | Controls the distance of the motion from its resting position. Use Assign modulation to choose a source. |
| Flow Speed | 0–2 | Sets how quickly flow changes or moves. Use Assign modulation to choose a source. |
| Luminescence | 0–2 | Sets how much high-frequency sound brightens the jellyfish glow; at 0 the glow ignores the treble, and higher values make it flare with the highs. Use Assign modulation to choose a source. |
Camera
| Setting | Available values | What it changes |
|---|---|---|
| Mouse Orbit | On / Off | Turns mouse orbit on or off. |

| Plankton Count | 0–4000 | Sets how many visible elements are drawn. |
| Fog Distance | 10–100 | Sets the spacing between visible elements. |
| Gamma | 1–3 | Sets the depth of the overall tone grade; higher values darken the midtones for a deeper, moodier underwater look, while 1 leaves them lighter. |
| Vignette | 0–1 | Sets how much the corners and edges of the picture darken; at 0 the whole frame is evenly lit, and higher values frame the jellyfish in a darker border. |
Some controls appear only after you enable a related mode or style. The settings panel always reflects the options available for the current selection.
Tips for a better audio visualization
- Use slower smoothing on body motion and faster response on glow so the subject feels alive without twitching.
- Try assigning Bass to Bloom Strength, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
