Particles
Man In White
Man In White is a particle-driven audio-reactive scene in BeamTracer Audio Visualizers, built on WebGPU. Settings, audio modulation, presets, and tips.
Man In White 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 Man In White
Launch the visualizer with its matching left-nav entry selected.
Move the figure with your hand
In this example, Hand is set to Draw Path: a pointing finger draws the line and this visualizer moves along it. Use the playback controls to pause or replay the motion.
- Switch to Performer, pick Man In White, and put your camera under it: open the FX Rack, add Visual Source, choose your camera and set its Visualizer to Over.
- Under Hand Tracking, leave Hand on Follow and raise a hand. The figure flies to it and stays under it on screen; push your hand toward the camera and it comes nearer, pull it back past your face and it falls away.
- Scatter sends it to the other side of the stage instead. With no hand in view it wanders on its own again.
Set Hand to Draw Path, then point with one finger and trace a loop in the air (or drag one with the mouse). The line shows while you draw, then the figure walks it, round and round for a closed loop or back and forth along an open stroke, until Path Life runs out. Hold up an open palm for a moment, or double-click, to clear it.
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 |
|---|---|---|
| Spawn Radius | Emission | Sets the visible spawn radius. |
| Turbulence | Forces & Curl | Sets how irregular or unpredictable the turbulence appears. |
| Attraction | Forces & Curl | Sets how strongly the particles are pulled back toward the shape they form; higher values hold the figure tightly together, while negative values push the particles away from it and scatter them. |
| Gravity | Forces & Curl | Sets the downward pull on moving elements. |
| Wind | Forces & Curl | Controls how strongly wind moves the scene. |
| Vortex | Forces & Curl | Controls the strength of the swirling motion. |

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