Frequency determination using discrete wavlet packet analysis

Started by lalit_vagabond November 17, 2010
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!

Tomtoms, smoke, mirrors and buzzwords. Drop it and do something useful. VLV

He seems to be providing entertainment to you. Perhaps you should pay him for his services.
