Best to "worst" (file encoded from flac and analyzed with Adobe Autidion):

AAC CBR400 = AAC CBR320 = AAC VBR.75. All three look exactly the same, or at least my eye doesn't see any difference (...or the difference doesn't explain 3 more MB for the CBR400).

AAC CBR256 = AAC VBR.65

MP3 CBR320

MP3 VBR -V 0


My suggestion, if you'd like to convert all of them go with AAC CBR320 or AAC VBR.75. Of course, if you can go/stay with FLAC/ALAC.

I use MP3 (LAME 3.99.4/3.99r) CBR320 but after this test, I will keep testing tomorrow, I will switch to AAC CBR320 for the few albums I keep on my iPhone.

This is not an ideal way to test lossy codecs, an encoder with a better psymodel could in theory produce an audibly better output than another even if a spectrum analysis suggests the former has preserved less of the signal. I think at these bit rates any quality difference is fairly academic as most people (myself included) could not ABX regular samples.
