Hello! I am trying to implement a student project which introduces phase distortions in a audio signal for select frequency range.But the frequency detection is done using DWPA FB which is very new to me! Please,can anyone explain me how to(on MATLAB): 1)decompose the signal at some level using discrete wavelet packet analysis into subbands. 2)then basically i want to choose the subbands between my required range. I want to use these subbands only for the phase distortions.Later i want to again synthesize the singal back. Thank you!

Drop it and do something useful. VLV
