ATTACK
Attack (like Release) is labeled in milliseconds. The setting represents the amount of time it takes
for the gain to change by a specified amount.
It would not be grossly incorrect to think of this setting as changing the slope of a graph depicting
how aggressively the compressor pursues the target value (defined by applying the Ratio setting to
the amount the signal surpasses the Threshold). Shorter values are more aggressive, while longer
values are more subtle (and tend to be less noticeable to the audience).
RELEASE
Release is similar to Attack in many ways, but refers instead to the speed with which the
compression effect is removed as a source signal falls back on its own so that it no longer exceeds
the Threshold.
GAIN
Naturally, compression impacts the overall output level of the source or output. The Gain control
allows you to compensate, bringing the post-compressor/limiter signal back to a comfortable
nominal range.
Hint: Different circumstances call for different Attack and Release strategies. For example, much
less aggressive settings could work nicely for vocals, but fail badly when applied to a snare drum.
Many websites provide suggestions on establishing the best compressor/limiter settings for
different environments.
3.10.4 NOISE GATE
FIGURE 11
The audio options panel also include a configurable Noise Gate for each audio source, as well as all
outputs. This lets you ensure that unwanted low-level sounds are prevented from inadvertently
intruding into the mix.
SECTION 3.11 CONFIGURE RETURN VIDEO INPUTS
Selection and adjustments of one or more video sources intended for Return to Caller purposes can
likewise be performed in a tab by the same name in the Configure Channel pane (Figure 12).
Note that each channel can be configured to use a different video source to return to the remote
caller, although in many cases you might choose assign the same source to supply all four channels
