I realize that this doesn't help you at all, but why use a dead format that compresses the recordings, when you can get a decent Tascam DR05 or DR07mkii for under $100, that writes uncompressed PCM files? Just add a micro SD card for like $20, and for around $100-$125, you have a rig that will last you a long time! And I could definitely be wrong, but if quality isn't a concern for you, I think that the Tascam decks record to mp3 as well as LPCM files! Can anyone confirm/deny that?
Just thought I would throw that out there since I honestly think you'd be much happier with the Tascam decks
