SignalTools Phase Meter
Display
The Phase Meter indicates the phase coherency
of two channels of a multi-channel signal.
The Phase Meter is green when the channels are
positively out of phase (values from 0 to +1) and
red when the channels are negatively out of
phase (values from 0 to –1).
At the center or zero position, the signal is a per-
fect stereo image. At the +1 position, the signal
is a perfect mono image. At the –1 position, the
signal is 100% out of phase.
SurroundScope With SurroundScope you can
select the two channels to compare by clicking
the channel buttons around the Surround Dis-
play. Selected channels are indicated in blue.
PhaseScope With PhaseScope, the left and right
channels are always compared.
Signal Tools Leq(A) Meter
Display
The Leq(A) Meter display lets you view the true
weighted average of the power level sent to any
channel or combination of channels (except the
LFE channel) in a multichannel track.
The Leq(A) Meter display shows a floating aver-
age for the level over the interval chosen in the
Window menu. For example, with a setting of 2
seconds, the display shows the average value for
the most recent 2 seconds of audio playback.
