AAC and VBR

Post by JonLawry »

In iTunes import preferences for the AAC format, there is a choice for VBR (Variable Bit Rate). This option isn't available (or I don't see it) for saving Amadeus Pro MPEG-4 audio files. When I save a file in AAC from Amadeus it doesn't indicate that it's VBR in iTunes (converting a file inside iTunes with VBR checked shows it that way). I looked around and found something indicating all AAC is VBR, but is that true? Interestingly, when I take the Amadeus-output AAC file and convert it to VBR in iTunes, it makes the file LARGER, which I find weird. Any ideas?
