You have to ability to convert audio files to a variety of formats from iTunes. The conversion leaves a duplicate in your iTunes library, but you can also locate the file. It can be useful, for instance, to convert AAC files to MP3 if you need to play them back in players that only support MP3. You can also convert video to formats supported by iOS devices and Apple TV.

Great video, but you didn't include how to rip audio from videos using iTunes.
