How can I convert AIFF files to MP3 files or some other compressed sound file (like MPEG-4 Audio: AAC)?
 
iTunes.

Just add it to your Library, set your importing preferences for MP3, AAC, or whatever, then right click or control-click on the track and select "Convert to MP3" (or AAC, or whatever you've specified in iTunes preferences).
