A
TTACK
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).
R
ELEASE
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.
G
AIN
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.
Noise Gate
The Audio Mixer's advanced 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.
An input Automation feature is also hosted in the Processing tab.
Follow Program Video
FIGURE 82
Enabling Follow Program Video options for an audio source directs it to track switcher operations affecting
the related video source. Audio for sources with Follow Program video enabled in the Audio Configuration
panel is automatically removed from mixed outputs until one or more specified video sources are actually
displayed on Program Output.
Hint: When the corresponding video source is not displayed on output, the audio source's VU meter
level is displayed as a grayscale.
