Open John Whitney
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 |
|---|---|---|
| Elements | Differential Dynamics | Sets how many moving points make up the pattern; more elements give a denser, more detailed figure. |
| Cycle Duration | Differential Dynamics | Sets how many seconds one full cycle of the pattern takes before it repeats; longer values make the pattern unfold more slowly. |
| Base Speed | Differential Dynamics | Sets how quickly base changes or moves. |
| Point Size | Display | Sets the visible point size. |
| Opacity | Display | Sets the overall transparency. |
| Line / Connection Width | Display | Sets the visible line / connection width. |
| Strength | Bloom | Sets the visible strength of strength. |
| Radius | Bloom | Sets the visible radius. |
| Zoom | Camera | Sets the visual zoom. |
| Rotation Speed | Camera | Sets how quickly rotation changes or moves. |

| Zero-Crossing Pulse | On / Off | Makes each tine swell briefly each time it completes a turn. Appears only in the MUSIC BOX scene. |
| Pulse Scale | 1x–3x | Sets how large each tine swells during its pulse. Appears when Zero-Crossing Pulse is on. |
| Show Reference Line | On / Off | Draws a line at the spot where each tine completes a turn. Appears only in the MUSIC BOX scene. |
Audio Target
| Setting | Available values | What it changes |
|---|---|---|
| Audio Target | SPEED, SIZE, SPREAD, COLOR | Chooses which part of the music the scene follows: SPEED follows the mid frequencies, SIZE and SPREAD follow the bass, and COLOR follows the high frequencies. |
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 Elements, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
