Speaking of which, I've always been fascinated by audio signal processing especially the idea of writing code to synthesize sounds or emulate vintage synthesizers. It feels like magic to turn mathematical formulas into actual audible melodies. But every time I look at a tutorial, I get intimidated by all the Fourier transforms and equations. Maybe I just need that one real opportunity to get started from scratch.
Libraries can abstract much of this. At least enough to get you started.
