Metering, Analysis, and Signal Generation

13.3.1 Phase Meter
The Phase meter is helpful when checking stereo-playback issues and mono compatibility.
There are two components to this meter: a large goniometer at the center of the plug-in
window and a correlation meter at the very bottom.
The goniometer displays left versus right channel amplitude on several axes. A line in the
following directions of the Goniometer display would mean:
• M-Axis. Mono signal
• +/-S Axis. Mono with one channel totally out-of-phase
• L/R Axes. Mono on one channel (left or right)
• M/S Axes. Channels in a Mid-Side (MS) encoded or recorded signal
The correlation meter shows the average amount of in-phase and out-of-phase audio signal.
Correlation meter parameters are:
• +1. Mono signal
• -1. Reversed-phase mono signal
• 0. Independent signals (true stereo or dual mono)
