Fracture

Fracture is a line-based audio-reactive scene in BeamTracer Audio Visualizers, built on WebGPU. Settings, audio modulation, presets, and tips.

Default demo track · live audio-reactive settings

Fracture 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 Fracture

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

Soundwaves · Crimson Flow · Ultraviolet · Arctic Pulse · Neon Garden · Black Velvet

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
Wave Amplitude	Audio Displacement	Controls the distance of the motion from its resting position.
Bass Amplitude	Audio Displacement	Controls the distance of the motion from its resting position.
Depth Amplitude	Audio Displacement	Controls the distance of the motion from its resting position.
Spectral Detail	Audio Displacement	Controls spectral detail; higher values increase the effect and lower values reduce it.
Thread Glow	Material	Sets the visible strength of thread glow.
Key Light	Shadow Room	Controls key light; higher values increase the effect and lower values reduce it.
Flow Speed	Animation	Sets how quickly flow changes or moves.
Audio Birth	Wave Particles	Controls audio birth; higher values increase the effect and lower values reduce it.

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 Wave Amplitude, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
