Chapter 13: SurroundScope 121
To understand the precise location of an audio
signal within the sound field, observe how the
circular sound pattern moves:
◆ A perfect circle in the center of the Surround
Display denotes a perfectly centered surround
signal—one that is panned equally to all chan-
nels.
◆ A signal that balloons toward the outer edges
of the display indicates which channels ema-
nate the strongest signal.
◆ A signal that is completely panned to one
speaker channel appears teardrop-shaped and
points toward the channel emanating the sig-
nal.
Lissajous Meter
When SurroundScope is inserted on a stereo
track, the standard Surround Display is replaced
by the Lissajous Meter.
The Lissajous Meter shows the relationship be-
tween the amplitude and phase of a stereo sig-
nal, enabling you to monitor and ensure perfect
stereo imaging.
The Lissajous Meter display is divided into four
quadrants, with left and right channels arranged
diagonally. When audio is panned predomi-
nantly to a particular speaker channel, a diago-
nal line appears, indicating the channel.
The Lissajous Meter displays in-phase material
as a vertical line and out-of-phase material as a
horizontal line.
Phase Meter
The Phase Meter indicates the phase coherency
of any two channels of a multichannel signal.
This enables you to see at a glance if a signal is in
or out of phase.
The Phase Meter is green when the signal is pos-
itively out of phase (values from 0 to +1) and red
when the signal is negatively out of phase (val-
ues from 0 to –1).
At center or zero position, the signal is a perfect
stereo image. At the +1 position, the signal is a
perfect mono image. At the –1 position, the sig-
nal is 100% out of phase.
By default, the meter displays the phase of the
left and right channels. However, you can select
any two channels for comparison by clicking
them.
