Does anyone use a tool for visuals that analyzes specific data (Velocity / density / speed) in Touch Designer's visuals?

I am working on a project that converts visual simulation into sound. Small particles on a black background move with a specific algorithm, and I’m trying to convert these data into sound using speed changes or overall density (by catching the entire movement, not just one piece of data). I would like to ask for advice if anyone uses visuals for this purpose, like analyzing sound with MFCC or other tools :slight_smile:
If anyone have some recommendation for using specific algorithms or tools,
let me know!
I will look on it!
