GapDezipperUsec=<0-1000> Integer 500 The audio engine will now render a smooth fade in
whenever audio playback is interrupted and there
is a abrupt transition in gain. The purpose of doing
this is to dezipper (smooth out) the gain transition
due to the discontinuity. For example, if you click
on the time ruler to jump to a new time location
during playback, the engine will smoothly render
the transition to the new gain level as a fade in.
This smoothing also takes place whenever
playback gapping occurs. You can control the fade
in time via the GapDezipperUsec variable, which
is expressed in microseconds per dB and controls
the speed of the fade in to the new gain value.
(default = 500 microseconds. i.e. the fade will take
500 microseconds per change in dB at the
transition point). You may increase or shorten the
time of the fade by increasing or decreasing this
value. The normal legal value range for this
variable is 0 to 1000 microseconds.
This variable should be set in the [Wave] section.
A value of zero turns off dezippering on gapping
completely.
MixDezipperUsec=<0-1000> Integer 50 This variable is similar to GapDezipperUsec
except that it controls how the mixer itself renders
abrupt gain transitions due to envelopes in the
project. This variable is expressed in
microseconds per dB and controls the speed of
the fade in to the new gain value (default = 50
microseconds). The normal legal value range for
this variable is 0 to 1000 microseconds.
This variable should be set in the [Wave] section.
Important: Changing the value of this variable will
affect how envelopes are rendered by the mixer
and may cause your mixes to sound slightly
different. Setting MixDezipperUsec too low can
cause clicks while rendering abrupt gain changes
due to envelopes.
AllowOfflineRenderMixThreads=
<0 or 1>
Boolean 1 A value of 1 (default) allows multiprocessing
during fast bounce when multiprocessing is
enabled in SONAR. Set to 0 to temporarily disable
multi-threaded mixing mixing during a fast bounce
operation.
