thanks for the reply!
also adding your note from the email which helps answer the original question:
Personally I’d use libsndfile [ http://www.mega-nerd.com/ ] to handle the WAV reading part, I’m pretty sure arturo has an addon around it too. There was intended to be an ofSoundFile to accompany ofSoundBuffer, but it get shelved (hence why ofSoundBuffer pretends files don’t exist).
