Processing & Parameters
3.8 Limiter
The Limiter is a dynamic range process. When the output signal reaches a certain level
(defined by the threshold parameter) the Limiter kicks in and keeps the signal level
from going any higher, preventing the output signal from overdriving amplifiers and/or
loudspeakers.
Limiter Parameters
The Limiter algorithm contains the following parameters:
• Limiter Enable - This parameter turns the limiter algorithm on or off.
•
Limiter Threshold (-60 dB - +3 dB)
- This parameter sets the level at which limiting
begins to occur. For example, if the threshold is set to -10dB, any signal level higher
than -10dB would trigger the limiter, while any signal levels lower than -10dB would
remain untouched. Generally, for speaker protection, you would want to use light
limiting, where most of the signal content remains just below the threshold and only
the peaks cross the threshold and get limited.
• Limiter Attack (0.1 ms - 1000 ms) - This parameter adjusts the attack time of the
limiter.
•
Limiter Release (0.1 ms - 1000 ms)
- This parameter adjusts the release time of the
limiter.
3.9 Mic Exciter
The Mic Exciter is a spectral enhancer for vocals. It applies gain to higher frequencies when
high frequency content is low, which clarifies the vocals making them sound crisp and clear.
Mic Exciter Parameters
The Mic Exciter algorithm contains the following parameters:
•
Exciter Enable
- This parameter turns the mic exciter algorithm on or off.
• Exciter Boost (0 dB - +12 dB) - This parameter adjusts how much boost (gain) is
applied to the high frequencies once the signal level has fallen below the set threshold.
•
Exciter Threshold (-24 dB - 0 dB)
- This parameter sets the level at which the vocal
exciter effect kicks in. If you set this parameter too low, it will continuously boost the
high frequencies and may make the vocal sound harsh. If it’s set too high the effect
may not kick in at all. Experimentation is key to obtain the desired results.
