Crash when loading 24 bit and 32 bit WAVs

Tried generating a couple of short WAV files at 24/48k and 32/48k respectively, however previewing or loading them causes NT to freeze (on melonDS at least).

edit: I was wrong, it works(?) after 20 seconds, however it uses drastically more RAM than it should and the loaded file (at least the one I tested) came out silent
