3. Finder

There are several options for converting audio files in OS X, but OS X also includes an audio converter built into Finder. First you should be noted that this method has some limitations compared to other audio converters. It can only accept AIFF, AIFC, Sd2f, CAFF, or WAVE files and can only output to four AAC presets. However, these presets cover a range of uses and should accommodate most Mac users who manage their music in AAC formats.

You can specify all sorts of options to control the input and output formats, such as “mp4f” -d “aac@44100″ /System/Library/Sounds/Basso.aiff ~/Desktop/basso_converted.mp4”.
