Medusae

Medusae is an organic animated scene in BeamTracer Audio Visualizers, built on WebGPU. Settings, audio modulation, presets, and tips.

Default demo track · live audio-reactive settings

Medusae 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 Medusae

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

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.

Presets and styles

Natural · Deep Sea · Electric

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	Material	Sets the visible bloom strength.
Bloom Radius	Material	Sets the visible bloom radius.
Bloom Threshold	Material	Sets the level that must be crossed before bloom appears.
Primary Hue	Colors	Moves the color around the color spectrum.
Physics Speed	Animation	Sets how quickly physics changes or moves.

Credits

Setting	Available values	What it changes
Source	Live readout	Shows the current source.
License	Live readout	Shows the current license.
Link	Live readout	Shows the current link.

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.
