Correlation tells you whether the left and right channels are working together or pulling apart.
A correlation meter compares the left and right channels. Positive values mean the channels are similar. Values near zero mean they are very different. Negative values warn that mono cancellation may be likely.
Correlation is not a width score. A wide mix can still be healthy, and a narrow mix can still have problems. It is a warning light for phase risk.
Momentary dips can happen with wide effects. Constant negative readings on core elements are more serious, especially if the vocal, kick, bass, or snare changes when summed to mono.
If a widening move makes the correlation meter unstable, check the mono fold before committing.
Use the meter to find moments worth checking, then listen in mono and stereo. The meter shows risk; the speakers confirm whether the musical result still works.
Meter Core places correlation beside loudness and M/S context so stereo width stays connected to the rest of the mix.
