Expander/Gate III Controls
This section describes controls for the Ex-
pander/Gate plug-in.
Input/Output Level Meters
The Input and Output meters show peak signal
levels before and after dynamics processing. See
“Levels Section” on page 65 for more informa-
tion.
Expander/Gate Dynamics Graph Display
The Dynamics Graph display lets you visually
see how much expansion or gating you are ap-
plying to your audio material. See “Dynamics
Graph Display” on page 66.
Look Ahead Button
Normally, dynamics processing begins when
the level of the input signal crosses the thresh-
old. When the Look Ahead button is enabled,
dynamics processing begins 2 milliseconds be-
fore the level of the input signal crosses the
threshold.
The Look Ahead control is useful for avoiding
the loss of transients that may have been other-
wise cut off or trimmed in a signal.
Threshold
The Threshold control sets the level below
which an input signal must fall to trigger expan-
sion or gating. Signals that fall below the thresh-
old will be reduced in gain. Signals that are
above it will be unaffected.
An orange arrow on the Input meter indicates
the current threshold, and can also be dragged
up or down to adjust the threshold setting.
The Dynamics Graph display also shows the
threshold as an orange vertical line.
This control has an approximate range of –60 dB
to 0 dB, with a setting of 0 dB equivalent to no
compression or limiting. The default value for
the Threshold control is –24 dB.
