Graph display Shows a curve that represents the level of the input signal (on the x–axis) and the
level of the output signal (on the y–axis). The orange vertical line represents the
threshold. Use this graph as a visual guideline to see how much dynamics
processing you are applying.
Side-Chain panel The side-chain is the split-off signal used by the plug-in’s detector to trigger
dynamics processing. The Side-Chain panel lets you toggle the side-chain between
the internal input signal or an external key input, and tailor the equalization of the
side-chain signal so that the triggering of dynamics processing becomes
frequency-sensitive.
For full information on how to work with the side-chain controls, see “Using the
Side-Chain Input in Dynamics III” in the Avid DigiRack Plug-Ins Guide. Search for
“digirack plug-ins guide” at www.avid.com.
Compressor/Limiter panel (COMP/LIMIT)
Knee Sets the rate at which the compressor reaches full compression once the threshold
has been exceeded. As you increase this control, it goes from applying “hard-knee”
compression to “soft-knee” compression. Values range from 0dB (hardest response)
to 30dB (softest response).
With hard-knee compression, compression begins when the input signal exceeds the
threshold. This can sound abrupt and is ideal for limiting.
With soft-knee compression, gentle compression begins and increases gradually as
the input signal approaches the threshold, and reaches full compression after
exceeding the threshold. This creates smoother compression.
The following illustration shows examples of hard knee and soft knee compression
in the graph display.
