is there a way to convert my recorded .caf files to .mp3 using the iPhone SDK / Core Audio, something else?
I've been looking around for a while, but all I've found was a command line uitility (which isn't allowed to run on the iPhone).
Regards
Since the iPhone shouldn't really be used for processor intensive things such as audio conversion, have you thought about transferring those files to your computer and running the conversion there using the command line tool you mentioned? I'm sure you could automate it pretty easily.
