When I select 128VBR (with Apple MPEG-4 (Audio) AAC (Medium Quality Setting)):
what is encoded is:
maxBitrate = 163360
avgBitrate = 141238
if I encode with iTunes:
maxBitrate = 160176
avgBitrate = 128000
and with afconvert -v -b 128000 -s 2 -f m4af -d aac
maxBitrate = 160176
avgBitrate = 128000
What would be the Max Pref Settings to replicate iTunes (....not that I want to do this, just trying to understand)
Thanks,
Tony
