What is this stuff? Radio engineers don't need
a lesson in dynamics processing, but for the ben-
efit of any jocks reading this, here's a quick ex-
planation of what these controls can do.
A Gate is a dynamics device whose function
is to remove unwanted audio material below a
certain threshold. A gain circuit is employed to
raise or lower the volume of the audio signal;
when the signal falls below a certain set thresh-
old, the audio level drops down to a predeter-
mined level. The reason they are called gates
is because when they "close" it sounds as if
the audio has suddenly stopped, or has been
"gated." You might use this on a mic channel to
eliminate background noise during times when
you're not speaking.
Threshold settings determine at what level the
processor will begin working. For example, on

a compressor, when signal level exceeds the
threshold setting, it will be compressed; below
the threshold the signal will remain uncom-
pressed. On a gate, threshold determines the
minimum input level required to cause the gate
to open up and pass signal; when input level
drops below the threshold, the gate will be closed
preventing signal from passing. Carefully setting
the threshold allows you to very specifically con-
trol when processing is being applied to a signal.
Compression controls the dynamic range of an
audio signal. It generally reduces the volume of
very loud audio, helping to keep from "blowing
out" the mic channel with too much volume. It
can be used to make your mic channel sound
"fatter," evening out the highs and lows of your
vocal pattern. It can also increase the overall
).
perceived fullness of your voice. Too much com-
pression, however, can make your voice sound
hard and "squashed." Use it sparingly!
To use compression, you must first set your
threshold value (usually expressed in dB). When
the audio signal is louder than this threshold, its
gain is reduced. The amount of gain reduction
applied depends on the Compression Ratio
setting. For example, with a 2:1 ratio, for every
2 decibels the input signal increases, the output
is allowed to increase only 1 decibel.
The Freeze Gate is used to prevent "suck-up"
of room noise during speech pauses. When ac-
tive, gain is not increased by the compressor
when audio is absent. "Freeze" would be the
default, since it almost always improves results.
De-Essing is just what you think it is - a way to
electronically remove extra sibilance from your
mic channel. If your mic is particularly sensitive
to "s" and "th-" sounds and accentuates them
on-air, De-Essing helps reduce these sounds to
more manageable levels. As with compression,
too much de-essing will produce annoying and
unnatural results - you'll wind up sounding like
you're talking through a cotton sock! Stick to
small amounts to get the effect you want.
