https://pages.mtu.edu/~suits/autocorrelation.html
Autocorrelation (for sound signals) "Autocorrelation" is used to compare a signal with a time-delayed version of itself. If a signal is periodic, then the signal will be perfectly correlated with a version of itself if the time-delay is an integer number of periods.
How to do autocorrelation with audio signal and parameters

To perform correlation between two signals, you can use ‘xcorr’ function. In ‘xcorr’, if you provide only one input, output will be the autocorrelation of the signal for different lags. [c,lags] = xcorr (x);

The auto correlation is simply the cross correlation of a signal with itself. An easy way to compute it is to do a convolution between the original signal and a time flipped version of the signal. If you have a signal that is 1000 samples long, than its auto correlation has 1999 (2*N-1) non-zero samples.

and zero for .. In matlab, the sample autocorrelation of a vector x can be computed using the xcorr function. 7.3. Example: octave:1> xcorr([1 1 1 1], 'unbiased') ans = 1 1 1 1 1 1 1 The xcorr function also performs cross-correlation when given a second signal argument, and offers additional features with additional arguments. Say help xcorr for details.
