All About Audio Phase and Correlation Meters – Craig ...
https://craiganderton.org/all-about-audio-phase-and-correlation-meters/
In brief, the Correlation meter (often a bar graph included with a Phase meter, but it may be separate) indicates a stereo signal’s mono compatibility. This was of crucial importance when mastering for vinyl, because it could indicate if there were out-of-phase audio components in the audio that could possibly cause the stylus to jump out of its groove.
Solution to Cross-correlation problem of 2 audio signals
https://dsp.stackexchange.com/questions/18233/solution-to-cross-correlation-problem-of-2-audio-signals
120000/8000 = 15 sec (length of audio X) 20000/8000 = 2.5 sec (length of audio Y) time1 (starting time) = 6.5001 sec time2 (ending time) = 9.0001 sec Just to make sure the code was correct, I plotted the impulse response of X & Y using fvtool & found that the impulse response of Y matches that of X between 6.5 to 9 seconds.

The transfer rate of the audio data, therefore, is 96 kbyte/sec when sampling frequency is 48 kHz and coding bit number is 16 bits. When they are 31.5 kHz and 8 bits, the transfer rate is 31.5 kbyte/sec ( Gibson, 1982 ). The correlation of a sample value between adjacent samples is high when data are digital audio.
Autocorrelation (for sound signals)
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. That fact, along with related experiments, has implicated autocorrelation as a potentially important part of signal …

In our case correlation means the similarity of two audio signals. These two signals can be: +100% correlated, i.e., both signals are identical (except that their levels may be completely different). -100% correlated, i.e., both signals are identical but inverted to each other (while their levels may again be different).
Q. What are my phase-correlation meters telling me?
https://www.soundonsound.com/sound-advice/q-what-are-my-phase-correlation-meters-telling-me
The meter is fed the left and right audio channels and displays the integrated phase correlation between them. If the two inputs are identical (a dual-mono signal) they are said to be ‘fully correlated’ and the meter indicates +1.

The correlation of both audio input channels, reduced to 9 bit, is calculated. The output is a signal between 0x0 and 0xFF, indicating the correlation (more specifically: the correlation rate) of -1 to +1. The display time constant is 0.5 s.
