• Hold button: Turn on to show a small indicator for the most recent peak level. This is
displayed as follows:
• Level Meter: A small yellow segment above each stereo level bar indicates the most
recent peak level.
• Correlation Meter: The horizontal area around the correlation indicator denotes
phase correlation deviations in real time, in both directions. A vertical line to the
left of the correlation indicator shows the maximum negative phase deviation value.
You can reset this line by clicking it during playback.
• Reset button: Reset all values in the Level Meter.
Logic Pro MultiMeter Correlation Meter
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.
Logic Pro MultiMeter Peak parameters
MultiMeter offers common Peak parameters for the Analyzer and Goniometer metering
tools. The Level and Correlation meters have discrete Peak parameters. See Logic Pro
MultiMeter Level and Loudness Meters.

• Peak pop-up menu: Choose the hold time for all metering tools. Choose 2, 4, or 6
seconds—or infinite.
Note: The (Peak) Hold button must be turned on for the selected time value to have
an effect.
