the threshold level. This control is calibrated in milliseconds
and values range from 0 to 500 ms. The compressor has an 8
sample lookahead buffer that allows it to have an “instant
attack” when you set the attack time to 0. Fast attack times
will control the transients of impulsive sounds. Use longer
attack times to let the transients through but control the sus-
tains.
R ELEASE CONTROL
The “Release” knob controls the release time of the compres-
sor. This knob is calibrated in milliseconds and can range
from 5 ms to 5 sec. The release time controls how quickly
the gain reduction returns to zero after the detector drops
below the threshold value. For settings below 40 ms or so the
compressor releases pretty abruptly and may introduce
unwanted artifacts into your audio, depending on the signal.
In addition, be careful making the release time faster than
the attack time.
U SING THE S IDECHAIN K EY INPUT W / SELECTABLE FILTER
The compressor provides a sidechain that processes audio
before the detector determines the current level. The
sidechain can process either the channel signal or some
external side chain input signal.
S IDECHAIN R OUTING B UTTON
This button (labeled “chan” in the illustration) is used to con-
trol the routing of the input signal to the compressor
sidechain. When the button is in the “chan” state, the signal
used by the sidechain is the signal being processed by Chan-
nelStrip. When the compressor is in the “sc-in” state, the sig-
