Using the MultiMeter’s Correlation Meter
The Correlation Meter gauges the phase relationship of a stereo signal. The Correlation
Meter’s 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 in the blue zone (between +1 and the middle 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.
Specialized Effects and Utilities
• When the Correlation Meter moves into the red area to the left of the center position,
out-of-phase material is present. This will lead to phase cancellations if the stereo signal
is combined into a mono signal.
