Event Horizon
Event Horizon is an ambient full-canvas background in BeamTracer Audio Visualizers, built on Canvas 2D. Settings, audio modulation, presets, and tips.
Event Horizon is an ambient full-canvas background in the Backgrounds category. Open it from the left visualizer list, start an audio source, and use the settings panel to shape its response.
Open Event Horizon
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

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 |
|---|---|---|
| Hue Shift | Colors | Moves the color around the color spectrum. |
| Aura Opacity | Colors | Sets how transparent the aura appears. |
| Disc Speed | Animation | Sets how quickly disc changes or moves. |
| Particle Speed | Animation | Sets how quickly particle changes or moves. |

Tips for a better audio visualization
- Use lower modulation amounts than you would for a foreground effect so the background supports the mix instead of competing with it.
- Try assigning Bass to Hue Shift, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
