I'm currently doing my major project on Non-uniform filter bank theory and application. I need your help and suggestions based the design of a non-uniform cosine-modulated filter bank (a 27 or 32 channel filter bank)and find it's application in the existing MPEG-1, Layer-III model ~ "MP3" audio codec, thereby replacing the hybrid filter bank which is employed in the existing one. However, I'm not sure about the feasibility and other related problems based on this. Therefore, I kindly request your valuable opinions or suggestions and especially necessary codes in MATLAB for a skelton framework based on this. Awaiting for a favourable reply with necessary codes if possible in MATLAB only. Yours faithfully SANJAY

In my opinion, if you are designing filter banks and want to find its
application in these popular audio codecs, you should establish a rule
to measure the quality of the filter banks, either based on its output
or the whole codec's output.
I suggest you first have one type of filter banks of the current
codecs implemented in Matlab for expriement or as a reference.
