I thinking why Microsoft destroy sound quality in new (after) WMA V2 codecs...Song listen at 64 Kb/s in WMA 2 sound good almost very good but if You encode song in Windows Media Player 10 at (coded WMA 9.1 64 Kb/s CBR) then you give sound poor quality muffled :\ crap. Now songs encode in in Windows Media Player 10 WMA 9.1 at 128 Kb/s CBR sounds like MP3 128 Kb/s so WMA 9 is not better than MP3 but give the same quality. I dont use VBR option because even in new VBR 50 WMA 9.1 when i have songs about 110 Kb/s then sounds worse than MP3 at 128 Kb/s. SO I must encode songs at 128 Kb/s in WMA 9.1 so bye WMA - better choice MP3 because is more flexible. Windows Media Team must write new codec not cutting highest frequency - WMA 9 Series gives the same sound quality like MP3... and Microsoft claims that WMA 9 gives the same quality at half size MP3... oh my good at half size gives quality like old radio - muffled
