Geometric Tunnel
Geometric Tunnel is an expressive audio-reactive composition in BeamTracer Audio Visualizers, built on WebGL. Settings, audio modulation, presets, and tips.
Geometric Tunnel is an expressive audio-reactive composition in the Creative category. Open it from the left visualizer list, start an audio source, and use the settings panel to shape its response.
Open Geometric Tunnel
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 |
|---|---|---|
| Speed | Animation | Sets how quickly speed changes or moves. |
| Color Reactivity | Animation | Sets how much the music shifts the color of the shapes in the tunnel; 0 keeps their color steady. |
| Pulse Reactivity | Animation | Sets how much the shapes swell and pulse in size with the music; 0 keeps them at a constant size. |
| Light Reactivity | Animation | Sets how much the tunnel lights flare brighter with the music; 0 keeps the lighting steady. |

Animation
| Setting | Available values | What it changes |
|---|---|---|
| Auto-Rotate Tunnel | On / Off | Turns auto-rotate tunnel on or off. |
| Speed | 0.2x–3x | Sets how quickly speed changes or moves. Use Assign modulation to choose a source. |
| Color Reactivity | 0–3 | Sets how much the music shifts the color of the shapes in the tunnel; 0 keeps their color steady. Use Assign modulation to choose a source. |
| Pulse Reactivity | 0–3 | Sets how much the shapes swell and pulse in size with the music; 0 keeps them at a constant size. Use Assign modulation to choose a source. |
| Light Reactivity | 0–3 | Sets how much the tunnel lights flare brighter with the music; 0 keeps the lighting steady. Use Assign modulation to choose a source. |
| Blend Time | 0.5s–10s | Sets how many seconds it takes to crossfade from one Variant to the next, so higher values give slower, smoother transitions. |
| Auto-Advance Sector | On / Off | Turns auto-advance sector on or off. |
| Sector Duration | 5s–120s | Sets how many seconds the tunnel stays in each Variant before moving on to the next. Available when Auto-Advance Sector is on. |
Camera
| Setting | Available values | What it changes |
|---|---|---|
| Mouse Orbit Camera | On / Off | Lets you drag with the mouse or touch to move the camera around the tunnel. While it is on, the built-in camera views are paused and Auto-Cycle Presets is hidden. |
| Auto-Cycle Presets | On / Off | Steps the camera through the built-in views automatically. Hidden while Mouse Orbit Camera is on. |
| Cycle Duration | 5s–60s | Sets how long the camera holds each view before moving to the next. Appears when Auto-Cycle Presets is on. |
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
- Assign different bands to structure, motion, and light instead of routing every control to Volume.
- Try assigning Bass to Speed, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
