attack times and heavy limiting, you should
generally use a proportionally longer release
time, particularly with material that contains
many peaks in close proximity.
Release Controls how long it takes for the Lim-
iter to be fully deactivated after the input signal
drops below the threshold level. In general, if
you use heavy limiting, you should use propor-
tionally longer release times in order to avoid
pumping that may occur when the Limiter is
forced to jump back and forth between limited
and unlimited signal levels. Lengthening the re-
lease time will help smooth these changes in
level by introducing a lag in the ramp-up/down
time of attenuation. Use shorter release times on
material with fewer peaks that do not occur in
close proximity to each other.
Graph Displays the response curve set by the
Limiter’s Threshold setting. As you adjust these
controls, refer to the graph to see how the shape
of this curve changes.
LFE Enable Enables plug-in processing of the
LFE (low frequency effects) channel on a multi-
channel track formatted for 5.1, 6.1, or 7.1 sur-
round formats on some plug-ins. To disable LFE
processing, deselect this button. For more infor-
mation on the LFE channel, refer to the Pro Tools
Reference Guide.
External Key Enables and disables side-chain
processing. Side-chain processing uses the vary-
ing amplitude of a separate reference track to
trigger limiting. See “Using a Key Input for Side-
Chain Processing” on page 16.
Key Listen When enabled, this lets you listen to
the reference track controlling the side-chain in-
put. This is often useful for fine tuning the Lim-
iter’s settings to the Key Input. Key Listen audi-
tions the right audio channel on RTAS and
AudioSuite versions of the Limiter.
Gate II
The Gate (also known as a noise gate) lets a sig-
nal above the selected threshold pass through to
the output at unity gain, without dynamic pro-
cessing. Once the input signal falls below the
threshold level, the gating shuts down the sig-
nal by fully or partially attenuating the output.
In this way, the desired signal is allowed to pass,
but unwanted signal is not. The Gate is useful
for noise removal on individual tracks, and can
be used for special effects such as cutting off a re-
verb tail.
Key Listen settings are not saved with other
plug-in settings.
