um...
I was a little disappointed. AAC is supposed to be the audio form of MPEG-4.
Knowing that I can achieve the quality of a 128Kbps MPEG-1 file with a 64Kbps MPEG-2 file (you can do that with iTunes), I was expecting to achieve the same quality with a 32Kbps AAC file. That was not the case. I could only achieve that at around 56Kbps.
AAC is the the audio the layer of MPEG-4
Not sure what you meant by that, MPEG-4 doesn't mean that the file output at the same quality is 4 times smaller...its just a number in a series assigned by the motion picture experts group for the compression format...
