Autocorrelation (for sound signals)
https://pages.mtu.edu/~suits/autocorrelation.html
Autocorrelation (for sound signals) (1) finding the value of the signal at a time t, (2) finding the value of the signal at a time t + τ, (3) multiplying those two values together, (4) repeating the process for all possible times, t, and then (5) computing the average of all those products.

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.

6 hours ago · For that purpose, I'm using a single channel wave file from here. My first experiment was to look at the auto-correlation of the signal as done by the following code. from scipy.io import wavfile from scipy import signal import numpy as np sample_rate_a, data_a = wavfile.read ('sounds/CantinaBand3.wav') corr = signal.correlate (data_a, data_a ...

The autocorrelation function depends on the power spectral components independent of the initial phases of the sinusoidal components. The independence of the phase (or sinusoidal or cosinusoidal waveforms) represented by the cosine functions lets the periodic nature be clearly observed rather than the original waveform itself.
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);

fact, the specific waveforms with which we deal are of finite length and have 0-autocorrelation off of the dc- component. Such waveforms are referred to as CAZAC waveforms, viz., Constant Amplitude Zero Autocorrelation. There is an ex-tensive literature on CAZACs because of the importance of such waveforms in communications and coding theory ...
