How to convert .caf to .mp3 file programmatically on the iPhone or iPad?

Question

is there a way to programmatically convert .caf audio files to .mp3 audio files on the iPad platform?

Can you do this server-side instead or does it have to be on the device? — iwasrobbed, Aug 13 '10 at 13:01

There is NO way to encode TO mp3 on the iPhone. Apple does not provide the encoders for mp3, presumably due to licensing.

OSStatus AudioConverterFillComplexBuffer(

   AudioConverterRef                   inAudioConverter,      
   AudioConverterComplexInputDataProc  inInputDataProc,   
   void                                *inInputDataProcUserData,   
   UInt32                              *ioOutputDataPacketSize,  
   AudioBufferList                     *outOutputData,  
   AudioStreamPacketDescription        *outPacketDescription  
);

Still working on an implementation, but this method is meant to be used for this conversion.

It is declared in audiotoolbox -> audioConverter
