signal interpolation after getting fft for voice signal ?
2 views (last 30 days)
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

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.
