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 
If anyone have some recommendation for using specific algorithms or tools,
let me know!
I will look on it!
