Fluidic Balls 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 Fluidic Balls

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

Default · Fire Swarm · Ocean Drift · Neon Storm · Zen Flow · Plasma

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
Size Pulse	Material	Sets the visible size pulse.
Background Hue Speed	Colors	Sets how quickly background hue changes or moves.
Flow Speed	Animation	Sets how quickly flow changes or moves.
Spawn Radius	Animation	Sets the visible spawn radius.
Curl Size	Animation	Sets the visible curl size.
Attraction	Animation	Controls attraction; higher values increase the effect and lower values reduce it.
Vortex	Animation	Controls the strength of the swirling motion.

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