There is AAC support. I use AAC with 3.0.0. The thing is that
(1) there is no intrinsic converter built in yet. from what i have been told this is a bit of a task to do since iTunes was built around the mp3 model. however there are utilities available that get quicktime pro to do the job just fine.
(2) when playing an song encoded with AAC specs, performing other processor intensive tasks would make the song glitch when using 10.1.5 and 3.0.0. Maybe this has been fixed: I have not had time to check.
scem0: After checking the matter out with various AAC buffs, I have been told that one should never, repeat never, re-encode and mp3 to this format. This is becuase both are very lossy. AAC and mp3 work on different data models. By using complex audio models based on constructive and destructive interferrance, both systems are able to produce sounds that sound nice to us. however, what happens is that mp3 is certain to remove parts of the mp3 required by the aac model to produce an equivalent nice sound. To give a quick analogy as i understand it:
mp3 might produce an output sound 5 by adding components 1 and 4
aac might produce an output of 5 by adding 2 and 3
mp3 encoders may think that values of 2 and 3 are redundant cause they are not required in their data model (that only requires 1 and 4). the aac format will therefore be unable to reproduce the sound accurately cause the 2 and 3 that it requires have been stripped from the sound file
Hope this is of help and not too complicated....
