how to apply fft for audio signal??????????????????
 

It's very simple. First you should record or read the audio signal. For that you should do the following:
If you want to give the input through a microphone then you should use the command: wavrecord

If you want to give take the input from a .wav file you should use the command wavread

After doing that all you have to do is to use this command : fft


If you want to know the syntax of these commands see the matlab help. If you have any trouble in doing that notify me I will help.

can u get a matlab code for an equation which i have already posted?????????
 

Do you think the phrase " which I have already posted" convey something to people around here? Try being precise.

Thank You.
 

HOW TO WRITE MATLAB CODE FOR THE FOLLOWING EQUATION????
w
E(K)=∑ A(E(k)-E(K+i))
i=-w

K=0:512
i=-402:402

A(X)=X for all x>=0
A(X)=0 for all x=0
 

iVenky can u give ur matlab codes????????and send it to vinujasaran@gmail.com
