Sound Brush is a line-based audio-reactive scene in BeamTracer Audio Visualizers. Shape its response in your browser with settings, audio modulation, presets, and tips.

Default demo track · live audio-reactive settings

Sound Brush is a line-based audio-reactive scene in the Wire category. Open it from the left visualizer list, start an audio source, and use the settings panel to shape its response.

Open Sound Brush

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

Silk · Deep · Neon · Fine · Pulse · Ropes · Shadow · Aloboi · Resonance

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
Waveform Scale	Core	Sets the visual waveform scale.
Emissive	Material	Controls emissive; higher values increase the effect and lower values reduce it.
Base Hue	Colors	Moves the color around the color spectrum.
Saturation	Colors	Moves colors from muted toward vivid.
Brightness	Colors	Sets the visible strength of brightness.
Flow Speed	Animation	Sets how quickly flow changes or moves.
Distance	Camera	Sets how far the camera sits from the subject.

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

Route bass to line width or displacement, then use mids for motion so the shape stays musical instead of only flashing.
Try assigning Bass to Waveform Scale, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
