Hi All, I want to design sub-band filtering for audio signal processing, the number of filter banks(Sub-bands) will be decided on the fly. Here are my queries reagrding this. 1. In filter bank implementation is FIR filter implementation or IIR fiter implementation is better. 2. Which would be the best method to go either a wavelet transform method or Pseudo-QMF filter bank. 3. which particular wavelet will be sutiable for the audio processing if wavelet transform is good. 4. which of the two methods is better in processing speed. Thanks a lot in advance, With regards, -Prasad
