Digital Rain
Digital Rain is a pixel-grid performance visual in BeamTracer Audio Visualizers, built on WebGPU. Settings, audio modulation, presets, and tips.
Digital Rain is a pixel-grid performance visual in the Matrix LED category. Open it from the left visualizer list, start an audio source, and use the settings panel to shape its response.
Open Digital Rain
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 |
|---|---|---|
| Fall Speed | Rain | Sets how quickly fall changes or moves. |
| Spawn Rate | Rain | Sets how quickly spawn changes or moves. |
| Hue | Colors | Moves the color around the color spectrum. |

Tips for a better audio visualization
- Use bass for large fills or zoom and highs for small pixel detail; this reads clearly even on a distant screen.
- Try assigning Bass to Fall Speed, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
