input signals.
SoundStructure devices include the following styles of look-ahead dynamics
processing.
Peak Limiter
Limiter
Compressor
Expander
Gate
The SoundStructure Studio user interface for adjusting the dynamics settings
are shown in the following figure.
The dynamics processing can be turned on or off for a channel by toggling the
enable button on either the channels page or on the dynamics control high-
lighted on the previous figure. As with other controls, dynamics processing
can be configured for a virtual channel or a virtual channel group. When
dynamics processing is applied to stereo virtual channels, the underlying left
and right dynamics processors will apply the same gain. Linked dynamics
processors apply gain as though the highest level input signal were applied to
both of their inputs.
The gate, expander, compressor, limiter, and peak limiter must be enabled
individually with their individual enable buttons. In the previous figure the
limiter is enabled. Once the dynamics processing is enabled, the dynamics pro-
cessing curve will update as adjustments are made to the dynamics processing
settings.
On the dynamics processing page there is also a fader control - the same fader
control found on the channels and matrix page- that can be used to add or
remove gain from the underlying virtual channel.
The Reset button may be used to return the Dynamics processing to its default
settings which leaves the signal unprocessed.
