MultiMeter Correlation Meter in Logic Pro for Mac

Correlation Meter gauges the phase relationship of a stereo signal.

Correlation Meter scale values indicate the following:

• A +1 correlation value indicates that the left and right channels correlate 100%. In other words, the left and right signals are in phase and are the same shape.

• Correlation values to the right of the center position indicate that the stereo signal is mono compatible.

• The middle position indicates the highest allowable amount of left/right divergence, which is often audible as an extremely wide stereo effect.

• When the Correlation Meter moves to the left of the center position, out-of-phase material is present. This leads to phase cancelations if the stereo signal is combined into a mono signal.

  Note: When plug-ins such as Chromaverb that offer stereo width or spread parameters are inserted before the Correlation Meter in the signal path, the Correlation Meter will show negative values when a width or spread parameter above 100% is used in such plug-ins.
