Surround MultiMeter Goniometer parameters
•
Goniometer button: Turn on to show the Goniometer results in the main display.
•
Auto Gain eld: Drag to set the amount of display compensation for low input levels. You can
set Auto Gain levels in 10% increments, or you can turn it o.
Note: To avoid confusion with the Auto Gain parameter found in other Logic Pro eects and
processors (such as the compressors), Auto Gain is only used as a display parameter in the
meters. It increases display levels to enhance readability. It does not change audio levels.
•
Decay eld: Drag to set the time it takes for the Goniometer trace to fade to black.
•
L–R, Ls–Rs, and Both buttons: Click to determine the channel pairs shown in the main display.
When you are using Surround MultiMeter in congurations with exactly two channel pairs
(quad, 5.1, and 6.1 congurations), the Goniometer can display both pairs if you select Both.
One pair (for L-R) appears in the upper half of the main display, and one (for Ls-Rs) appears in
the lower half.
Surround MultiMeter Level Meter
The Level Meter displays the current signal level on a logarithmic decibel scale. The signal level
for each channel is represented by a blue bar.
RMS and Peak levels are shown simultaneously, with RMS levels appearing as dark blue bars,
and Peak levels appearing as light blue bars. When the level exceeds 0 dB, the portion of the bar
above the 0 dB mark turns red.
Current peak values are displayed numerically (in dB increments) above the Level Meter. Click in
the display to reset peak values.
