Chapter 4: Focusrite D3 23
Release
Release controls how long it takes for the com-
pressor to be fully deactivated after the input
signal drops below the threshold level. In gen-
eral, this setting should be longer than the at-
tack 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 reduction 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 ef-
fect on release time. Instead, the D3 uses a re-
lease time value that is program dependent and
based on the audio being processed.
D3 Limiter Controls
The Limiter icon, which represents a limiter
curve, acts as a three-state switch for enabling,
disabling, or bypassing the limiter. Its current
state is indicated by the icon’s color:
• White indicates enabled. In this state, the
limiter is active and using available DSP re-
sources.
• Black indicates disabled. In this state, the
limiter is not using DSP resources.
• Gray indicates bypassed. In this state, the
limiter is not active, but is still using avail-
able DSP resources.
To disable the limiter:
■ Start key-click (Windows) or Control-click
(Mac) the icon. When the limiter is disabled, the
icon is black.
To re-enable the limiter:
■ Click the icon. When the limiter is enabled,
the icon is white.
