Identical signals in both channels have a correlation of +1; completely unrelated signals have a correlation of 0. Normal stereo mixes mostly show correlation values between 0.3 and 0.7. When both channels carry identical signals but one channel's polarity is switched (180 phase), the correlation will be -1.
When analyzing audio using the Correlator, please ensure that the display does not read negative values (shown in red) across extended periods. If a stereo mastered mix contains phase-modulated components and is turned to mono, unintentional strong sound changes are caused because the included phase-shifted components eliminate each other.
