You can use the Metering tools to analyze audio in a variety of ways. These utilities have
no effect on the audio signal. They are simply used as diagnostic aids.
This chapter covers the following:
Correlation Meter (p. 91)
MultiMeter (p. 91)
Surround MultiMeter (p. 96)
Tuner (p. 102)
Correlation Meter
The Correlation Meter displays the phase relationship of a stereo signal.
A correlation of +1 (the far right position) means that the left and right channels correlate
100%—they are completely in phase.
A correlation of 0 (the center position) indicates the widest permissible left/right
divergence, often audible as an extremely wide stereo effect.
Correlation values lower than 0 indicate that out-of-phase material is present, which
can lead to phase cancelations if the stereo signal is combined into a monaural signal.
MultiMeter
The MultiMeter provides a collection of professional gauge and analysis tools in a single
window. It includes:
An Analyzer to view the level of each 1/3-octave frequency band
A Goniometer for judging phase coherency in a stereo sound field
