Hello!

I'm getting started to audio processing. I've been trying to analyze sounds on a Squash court, and have a pretty introductory understanding to STFT.

In my head, I'm imagining that the sound of a ball has some fingerprint X, and the sound of footsteps has a sound fingerprint Y, and the audio is some nonlinear combination of that plus background noise.

How does that combination of frequency profiles happen? Can I come up with a rough "fingerprint" and just subtract it from the audio file?

If it helps, I'm doing work in Python, mostly using Librosa

Thanks!
