How do I implement cross-correlation to prove two audio ...

In signal processing the cross-correlation (xcorr in MATLAB) is a convolution operation with one of the two sequences reversed. Since time reversal corresponds to complex conjugation in the frequency domain, you can use the DFT to compute the cross-correlation as follows: R_xy = ifft(fft(x,N) * conj(fft(y,N)))
Understanding The Cross Correlation Function
http://blog.prosig.com/2001/06/06/correlation-example/
A cross correlation technique and a transfer function like approach were used to determine the location. To simulate the noise a broad band Gaussian signal was bandpass filtered from 500 to 1500Hz. This random signal, s (t), was generated at 10000 samples/second. Two delayed signals, p 1 (t) and p 2 (t), were then formed.

Cross-correlation is the comparison of two different time series to detect if there is a correlation between metrics with the same maximum and minimum values. For example: “Are two audio signals in phase?” Normalized cross-correlation is also the comparison of two time series, but using a different scoring result. Instead of simple cross-correlation, it can compare …
matlab - How do you cross-correlate audio files to see if ...
https://stackoverflow.com/questions/66270939/how-do-you-cross-correlate-audio-files-to-see-if-a-sample-matches-the-original
A broad overview of this process involves doing the cross-correlation between each signal and the ten second sample. After doing the cross-correlation we find take the maximum, max() which will give us a factor of "best fit" (most correlation) for each of the comparisons. We then take the maximum result of the peak-correlations to find which of the …

Autocorrelation is the result of cross-correlating a function with itself. Equation (8-1) becomes φ xx(t)=x(τ−t)x(τ) −∞ ∞ ∫dτ (8-9) and equation (8-4) becomes Φ xx=FT⎡⎣φ xx(t)⎤⎦=X*(f)X(f)=X(f) 2 (8-10) From the expression of the Energy used in the derivation of Parseval’s theorem (equation 7-9)
What is "Interaural Cross Correlation (IACC)"?
https://www.sweetwater.com/insync/interaural-cross-correlation-iacc/
Interaural Cross Correlation (IACC) Share this page: By Sweetwater on Oct 4, 2002, 12:00 AM. The measure of the difference in signals received by two ears of a person. IACC values range from -1 to +1. A value of -1 means the signals are identical, but completely out of phase. +1 means they are identical, and 0 means they have no correlation at all. The IACC will be nearly …

Given 1d signals A and B. Computing a signal C[x] as: C[x]=SUM( A[x]*B[x+j] ) //sum over j gives what some call linear correlation or just (cross)correlation of A and B. (is that correct?) It is used to check where signals match most ( for some position …
Cross-correlation - MATLAB xcorr
https://www.mathworks.com/help/signal/ref/xcorr.html
r = xcorr (x,y) returns the cross-correlation of two discrete-time sequences. Cross-correlation measures the similarity between a vector x and shifted (lagged) copies of a vector y as a function of the lag. If x and y have different lengths, the function appends zeros to the end of the shorter vector so it has the same length as the other.
