Strange Attractors
Strange Attractors is a particle-driven audio-reactive scene in BeamTracer Audio Visualizers. Shape its response in your browser with settings, audio modulation, presets, and tips.
Strange Attractors 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 Strange Attractors
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 |
|---|---|---|
| Particle Size | Material | Sets the visible particle size. |
| Particle Opacity | Material | Sets how transparent the particle appears. |
| Dissolve Intensity | Material | Sets the visible dissolve intensity. |
| Hue | Colors | Moves the color around the color spectrum. |
| Saturation | Colors | Moves colors from muted toward vivid. |
| Brightness | Colors | Sets the visible strength of brightness. |
| Simulation Speed | Animation | Sets how quickly simulation changes or moves. |
| Param Morph | Animation | Changes one of the selected formula’s shape parameters. |
| Camera Distance | Camera | Sets how far the camera sits from the subject. |

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