All About Audio Phase and Correlation Meters – Craig ...

The Correlation meter reading spans the range between -1 (the right and left channels are completely out of phase, with no correlation) and +1 (the right and left channels are identical, and correlate completely). With most mixes, the bar graph will fluctuate between 0 and +1. MONO READINGS Mono audio indication
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 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.

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).
