Dynamics
The Dynamics section of Channel Strip provides
Expander/Gate, Compressor/Limiter, and Side
Chain processing all in one. This section also
provides a dynamics graphic display for the
Compressor/Limiter and Expander/Gate
plug-ins. The display shows a curve that repre-
sents the level of the input signal (on the hori-
zontal x–axis) and the amount of gain reduction
applied (on the vertical y–axis). The vertical line
represents the threshold.
Dynamics Graph
The Dynamics Graph display—used with Ex-
pander/Gate and Compressor/Limiter process-
ing—shows a curve that represents the level of
the input signal (on the horizontal x–axis) and
the amount of gain reduction applied (on the
vertical y–axis). The display shows two vertical
lines representing the Threshold setting for the
Expander/Gate and Compressor/Limiter, re-
spectively.
The Dynamics Graph display also features an
animated red ball in the gain transfer curve dis-
play. This ball shows the amount of input gain
(x-axis) and gain reduction (y-axis) being ap-
plied to the incoming signal at any given mo-
ment. To indicate overshoots (when an incom-
ing signal peak is too fast for the current
compression setting), the cursor temporarily
leaves the gain transfer curve.
Use this graph as a visual guideline to see how
much dynamics processing you are applying to
the incoming audio signal.
Dynamics Graph Gain Reduction
Resolution
Channel Strip lets you view the gain reduction
scale on the Dynamics Graph display either in
3 dB increments from 0 dB to 18 dB or in 6 dB
increments from 0 dB to –36 dB.
To change the Dynamics Graph Gain Reduction
resolution:
 Click the Graph Resolution toggle.
