How much will WMA9 compression be better than WMA8? Will WMA9 get better than MP3Pro at mailmusic (64kbps or less)? Will WMA9 use VBR, ABR, SBR?
I did small tests - very small, but concluant I think.
WMA9 at very low bitrate is a least different from mp3pro VBR. For my taste, and on the (classical) music I tested, mp3pro VBR was better (don't forget that wma9 is only on beta version)
WMA9 = CBR, VBR and Lossless
