Are you trying to generate MP3 or another format? If you want to 
convert your AIFF into something that is not MP3 (AAC for example), 
there is better way than using iTunes. Else, as OS X does not include 
an MP3 converter (for legal issues), you will have to use iTunes (or 
another third party library like LAME).
