I didn't think compressed/adpcm audio reading like this was possible in actionscript, but i haven't fooled around with flash much since flash cs3, and even then i stuck to as2. Very nice.
The playback engine is nearly complete. But I can't get the final formulas down. Could someone please help me out with the frequencies and pitches? I have no idea what I should be doing there.
Seems like the frequencies and pitches are sorted out now. I only have minor stuff left now. Like figuring out why modulation is currently crashing and what's wrong with the volume calculations.
