Focusrite D2 and D3 Plug-Ins Guide20
Threshold
Threshold sets the threshold level. Signals that ex-
ceed this level will be compressed. Signals that are
below it will be unaffected. The range of this con-
trol is from 0 dB to –48 dB. A setting of 0 dB is
equivalent to no compression.
Attack
Attack sets the compressor attack time. To use
compression most effectively, the attack time
should be set so that signals exceed the threshold
level long enough to cause an increase in the aver-
age level. This helps ensure that gain reduction
doesn’t decrease the overall volume. The range of
this control is from 1.0 ms to 150.0 ms.
Release
Release controls how long it takes for the compres-
sor to be fully deactivated after the input signal
drops below the threshold level. In general, this
setting should be longer than the attack time and
long enough that if signal levels repeatedly rise
above the threshold, they cause gain reduction
only once. If the release time is too long, a loud
section of the audio material could cause gain re-
duction that persists through a soft section. The
range of this control is from 25 milliseconds to 2.5
seconds.
Auto Release
Auto Release enables the automatic release func-
tion. In this mode the Release control has no effect
on release time. Instead, the D3 uses a release time
value that is program dependent and based on the
audio being processed.
