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.

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.
