Nope. Just need to pull some meeting notes from it. I'm thinking the metadata is jacked up.

Seems just moov box missing. Probably file was not finalized properly, due to premature termination of writing software or hardware. The following worked. If you want rescued file, I can upload it and will let you know.
CODE
$ dd ibs=1 skip=44 if='your broken file.m4a' of=raw.aac
$ faad -a adts.aac raw.aac

Hey!

I'm having corrupted m4a file issue as well. I recorded an interview today with iPhone 4's Voice Memo app and the recorded file won't play. I'd be very thankful if someone could take a look at it smile.gif
