Can you please send me the link,I looked the website but I have found some codes very complicated.
I really dont know,when we plot the autocorelation by Matalb function (xcorr) what is the x axis?
If I want to see the lags should I use any specific formula?Is the pitch periods are exactly the lags?
Can you please give me some useful refrences.
