SIBILANCE
The
distortion

a
particular frequency are boost or cut.
SLOPE
In a filter or equalizer,
a description of the rate of boost or attenua¬

Usually specified in dB/octave (6, 12, 18, and 24dB/octave slopes
are most common).
The steeper the slope, the higher the "Q" in a filter.
THRESHOLD
An arbitrary signal level, above which a limiter or noise gate activates.
TRANSIENT
A sudden burst of energy in an audio signal,
such as a breath blast in a
microphone,
the
sound of a snare drum,

record.
Transients
frequently
reach peak levels of 10 to 30 dB
above
standard
operating level, and may cause distortion or even damage to equipment.
UNITY GAIN
Output level = Input level.
VGA
Voltage
Controlled
Amplifier.
An amplifier capable of both
gain
and
loss, controlled by a variable DC voltage.
