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 4:1
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

information about audio codecs.
