dear all

kindly, I would If some one could explain me the below :

1- I recoreded a wave file

2- import it to mat lab

3- complete fft for the signal

now I need to calculate the peak for the signal and connect them by a curve to have the signal pitch envelop

your support would be appreciated

Hi Haider,

I understand that you have computed fft of the signal imported and wish to plot its upper peak envelope. You can use 'envelope' function and specify 'peak' as an argument to obtain the peak envelopes.
