Apple Compressor 3 - Manual (Page 242)

Choosing an Audio Codec
AAC is a good general-purpose audio delivery codec and it is compatible with a wide
variety of playback devices. For QuickTime movies playing on slower computers, IMA is
a better choice because it is less computer intensive, thus allowing the computer to focus
on the more challenging video stream. See
QuickTime Audio Codecs for more information
about audio codecs.
