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'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 😱
