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)))

Cross-Correlation Signal Processing. Highly accurate Cross-correlation detection for time difference of arrival (TDOA) for wide bandwidth modulated signals is achieved using a Guzik ADP7104 32 GS/s digitizer.. The accuracy is ensured by real-time ADC equalization, precise channel synchronization, channel time alignment and signal processing (averaging and …

https://stackoverflow.com/questions/25410985/using-cross-correlation-to-detect-the-beginning-of-a-signal
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 …
Time Series Analysis: The Cross-Correlation Function

The concept of cross-correlation has been developed in two distinct fields: signal processing and statistics. In the area of signal processing, the cross-correlation function can be used to transform one or more signals so that they can be viewed with an altered perspective.
