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.
