It’s one file in that repository - the python file. The rest (written in C) is not.

Also note that the python visualizer tool has been basically written by vibe-coding. I know more about analog filters – and that’s not saying much – than I do about python. It started out as my typical “google and do the monkey-see-monkey-do” kind of programming, but then I cut out the middle-man – me – and just used Google Antigravity to do the audio sample visualizer.
