    Why is ACC (iTunes' music files) file extension *.m4a instead of *.acc??? :confused:

    'cause ACC is Mpeg-4 Audio.

    I guess it's because aac can either be MPEG2 audio layer or MPEG4 audio layer... and this way you know which... ;)

    .AAC was already taken for the MPEG-2 version of AAC, so .M4A was created for AAC's MPEG-4 incarnation.

    I thought this was a thread about Duke University and their iPods.

    I'm not surprised. "ACC" is a common misspelling of "AAC", especially on these forums.

    EDIT: Of all words I could have spelled incorrectly, "misspelling" was the one I got wrong :eek:
