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

Cross-correlation and convolution are closely related. In short, to do convolution with FFTs, you. zero-pad the input signals a and b (add zeros to the end of each. The zero padding should fill the vectors until they reach a size of at least N = size(a)+size(b)-1); take the FFT of both signals
How to cross correlate two audio files
https://www.mathworks.com/matlabcentral/answers/691995-how-to-cross-correlate-two-audio-files
Hello, I'm trying to cross correlate of two audio files and plot them but the problem is; it doesn't show the 3rd signals when I plot it which is the correlation of the audio files. [x,fs]=audioread( "Word14.wav" );

Cross correlation removes the mixer and baseband LNA noise from the measurement results. Referring to the block diagram of the Dual Channel Cross Correlation Set Up shown in Figure 3, the FFT analyzer analyzes the data from two measurement channels for correlation. The phase noise from the device

I am using cross-correlation to find where an audio signal occurs within a recording. When doing this, the point of highest correlation is always found somewhere within the signal in the recording, but I'm looking for a way to find the point where that signal BEGINS in …

zero or negative indexes the cross correlation sample with zero lag is the central element in the output vector. An alternate way of doing the cross correlation without padding with zeros is using the conv command (phixy = conv(y,x(end:-1:1))) ESS 522 2014 8-2 Autocorrelation

Upon calculating the cross correlation, decision unit 996 undertakes analysis of the cross-correlation vector to determine a peak and the lag at which this peak occurs. The decision unit 996 searches for a high coherence or a correlation with a maxima at lag zero to indicate that the origin of the sound source is equidistant to the input sound ...

mixers and cross correlation. signal of the DUT first passes a wave guide splitter. After the splitter the external harmonic mixers are connected. The two internal reference sources are used as local oscillators (LO1 and LO2). The signal is down converted to an IF frequency, which is in the range of several MHz. ...
Cross-correlation - Wikipedia
https://en.wikipedia.org/wiki/Cross-correlation
In signal processing, cross-correlation is a measure of similarity of two series as a function of the displacement of one relative to the other. This is also known as a sliding dot product or sliding inner-product.It is commonly used for searching a long signal for a shorter, known feature. It has applications in pattern recognition, single particle analysis, electron tomography, averaging ...
