Im building some music playback software and am currently struggling with the implementation of a spectrum analyzer to visualize the music.

This is incredible stuff and I learned a lot. Well done sir.

Ps, also mourning the loss of Fable! It sorted out a 3 month bug hunt odyssey in 3 days. For a somewhat novel problem in a pretty niche area (DSD DoP audio crackle problems during certain playback edge cases).
