filter bank : design n application - Sanjay S - Feb 2 3:46:00 2005



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

Re: filter bank : design n application - Franson - Feb 4 4:50:00 2005

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.
