I did the same thing for a device I made based on the Pi Pico[1], where audio is processed every sample and it stores a bunch of wav files in the flash that can be mangled together. the flash is fast enough that you can jump between samples really quickly to get cool "tunneling" effects that are surprisingly good sounding for such a tiny + cheap little chip.
this actually works surprisingly well!
