Hey list,
It happens once in a blue moon, but I get gut-wrenching emails from customers explaining that they were in the middle of recording some important audio in TapeDeck (http://tapedeckapp.com), when their system crashes on them.
The crashes aren't always my fault, but it's definitely my problem to try and figure out!
When examining the busted MPEG-4 audio files, it would appear that the entire header is zeroed out while recording. I suspect it is written out during ExtAudioFileDispose(), which obviously isn't called until the recording is stopped successfully.
Given that my MPEG-4 encoding parameters are known, and that I used a constant bit rate, is there any way of recovering the audio data contained in the file?
Also, is there anything I can do during recording in order to "flush" the header to the file periodically and minimize the risk of this occurring in the future?
Thanks,
Chris Liscio
