Trails
Trails is a particle-driven audio-reactive scene in BeamTracer Audio Visualizers, built on Canvas 2D. Settings, audio modulation, presets, and tips.
Trails is a particle-driven audio-reactive scene in the Particles category. Open it from the left visualizer list, start an audio source, and use the settings panel to shape its response.
Open Trails
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.

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 |
|---|---|---|
| Orbit Radius | Material | Sets the visible orbit radius. |
| Max Scale (Click) | Material | Sets the visual max scale (click). |
| Orbit Speed | Material | Sets how quickly orbit changes or moves. |
| Line Width | Material | Sets the visible line width. |
| Particle Size | Material | Sets the visible particle size. |

Tips for a better audio visualization
- Let bass control particle scale or spread, while highs drive sparkle or trail detail for a clearer sense of depth.
- Try assigning Bass to Orbit Radius, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
