MPEG-4 LD problem

Started by April 28, 2006
Hello all,

I am trying to implement some unsymmetrical windows in Mpeg-4 LD. I acheived a delay reduction in filter bank but when tested with some standard test signals.I found little bit distorted in test signals.I would like to check PR in MDCT filter bank(alone).Any suggestions/revelant papers or books to find the problem.Please let me know.

Thanking you,
