Release
The Release control sets how long it takes for the
gate to close after the input signal falls below the
threshold level and the hold time has passed.
This control ranges from 5 ms (fastest release
time) to 4 seconds (slowest release time).
Range
The Range control sets the depth of the Ex-
pander/Gate when closed. Setting the gate to
higher range levels allows more and more of the
gated audio that falls below the threshold to
peek through the gate at all times.
This control ranges from –80 dB (lowest depth)
to 0 dB (highest depth).
Side-Chain Section
The side-chain is the split-off signal used by the
plug-in’s detector to trigger dynamics process-
ing. The Side-Chain section lets you toggle the
side-chain between the internal input signal or
an external key input, and tailor the equaliza-
tion of the side-chain signal so that the trigger-
ing of dynamics processing becomes frequency-
sensitive.
See “Using the Side-Chain Input in Dynamics
III” on page 76.
De-Esser III
The De-Esser reduces sibilants and other high
frequency noises that can occur in vocals, voice-
overs, and wind instruments such as flutes.
These sounds can cause peaks in an audio signal
and lead to distortion.
The De-Esser reduces these unwanted sounds us-
ing fast-acting compression. A Threshold con-
trol sets the level above which compression
starts, and a Frequency control sets the fre-
quency band in which the De-Esser operates.
Using De-essing Effectively
To use de-essing most effectively, insert the De-
Esser after compressor or limiter plug-ins.
The Frequency control should be set to remove
sibilants (typically the 4–10 kHz range) and not
other parts of the signal. This helps prevent de-
essing from changing the original character of
the audio material in an undesired manner.
Similarly, the Range control should be set to a
dB level low enough so that de-essing is trig-
gered only by sibilants. If the Range is set too
high, a loud, non-sibilant section of audio mate-
rial could cause unwanted gain reduction or
cause sibilants to be over-attenuated.
