Limiter Attack (Lim Attack)
This controls how rapidly the limiter will
act to control audio peaks. We made the range
of this control 0.3ms to 100ms; however, we
recommend operating with settings between
0.3 and 10ms. With settings slower than this,
peak control will be sloppier, and though the
multiband limiter attack setting isn’t critical,
slowish attack times will make the final peak
limiter work harder.
Limiter Release (Lim Release)
This control sets how quickly the limiter
recovers once a peak has passed and the audio level falls below the limit threshold. The
adjustment range of this control is 3ms to 100ms.
Very fast release times (under 30ms and especially in the low band) coupled by very
fast attack times (under 5ms) will yield a tightly controlled audio signal that has a “radio”
sound. Very slow release times (greater than 50ms) will yield a more open sound that
is still well controlled (relative to the attack time settings). As we have said with the
AGC/Compressors, unless you are very familiar with these types of controls, it’s probably
best to not wander too far from the settings in the factory presets.
Output Trim
Each limiter band is followed by its own Output Level mix control which can be used
to make fine adjustments to the final tonal balance. Because the setting of these controls
can be fairly touchy, we recommend leaving them at 0dB unless a specific sonic effect
is desired.
Multiband Limiter Options
The multiband limiter is equipped with two other operating modes besides simply on and
off. On and Off is controlled by the check box labeled MB Lim. The other two options
require some explanation.
MB Lim Soft
– Checking this box enables a small amount of anticipation in the limiter
behavior, causing it to start to limit approximately 2dB below the absolute limit threshold
as set by the Band x Thresh control. This anticipation serves to soften the limiter action by
making it “spongy.” That is, it will ooze in and out of limiting in a softer fashion which
makes it quite effective (and good sounding) in voice applications.
Bass Enhance
– This check box enables a Vorsis-proprietary algorithm which enhances
low bass without creating intermodulation distortion or muddiness. It enhances the sound
of bass when heard on small, bass shy speakers and adds richness to the sound without
adding noticeable distortion.
