Hello. I'm looking for a way to encode an mp3 file on the iPhone. I'm writing an app that records an audio clip with the microphone and uploads it to a server. The iPhone SDK has APIs to write out .caf and .aiff, but I didn't find any support for mp3. Since I'm uploading to a server, these uncompressed formats are way too big--hence my i...
