Looking at the recent tests on 64kb files, I was wondering how come AAC underperforms compared to OGG, WMA and whatever else? I thought AAC was able to handle low bitrates very well due to it's type of encoding... if so, how come these other formats are beating it? Is it something that can be worked on in future releases from Psytel? Spose they would of been working mainly on high bitrate quality to whoop MPC's ass? :o)
