dillee1, what do u use to encode AAC+.......
I used the encoder from nero6.....
when I use the 50K-70K he aac preset........
the quality is much worse than wma......
or maybe i'm using the wrong decoder that dosen't do SBC......
I guess you are not using Nero Waveedit to play back the encoded AAC+ mp4 file.
Currently only Nero Waveedit is capabable of decoding the SBR part properly. Real Player, Quicktime 6, evivo, mp4player and 3ivx none of them are currently able to understand SBR.
Without SBR, high fequency is not reproduced and the reproduced sound is very dull and distorted.
Beside Nero Waveedit, Nero Showtime do provides dshow filter for AAC+ playback. However it always crash on Win 2003 platform.
May be you can try out Showtime and tell me your results. :D
Ahead will release the SBR decoder code under GPL on 25 this month, probably we will see a new version of CoreAAC decoder with SBR support at the end of month then.
