digital audio & animoto

AAC: Advanced Audio Coding, Itunes default.
MP3: MP is short for MPEG (Moving Picture Experts Group) &; 3 refers to "audio layer 3".
AIFF: Audio Interchanged File Format, an uncompressed audio file.

Audio File Size Comparisons:

AAC:.......................................6.4 MB
MP3 (greater):..........................4.7 MB
MP3 (good):.............................3.2 MB
AIFF:.......................................34.5 MB

At first, when comparing the quality of the files, I didn't notice much of a difference at all.  Only when I compared the uncompressed AIFF file and the lowest quality MP3 side-by-side did I notice that a lot of subtleties are lost in the MP3, but it doesn't sound bad by any means.

When putting a lot of music on your computer, I would use a high quality MP3 or AAC file, because they're all relatively small files without sacrificing quality.
