Threshold
When the input signal falls below the threshold, the
Expander/Gate starts working. This means that the higher
threshold the more expansion or gating you will get.
EXPANDER/GATE
Ratio
This is the Ratio of the gain reduction. If the Ratio is set to
4:1 it means that for every 1dB the ínput signal decreases,
the output will decrease by 4dB.
When the Ratio is set to Infinite:1, it means that when the
input signal falls below the threshold, the output is turned all
the way down. This is also known as Gating.
Attack
The Attack time is the fallback time that the Expander/Gate
uses to reach the gain reduction specified by the Ratio
parameter.
Example: If the input signal suddenly drops 4dB below
threshold in no time with the Ratio set to 4:1 and the Attack
set to 20ms, the FireworX will use 20ms to reach the gain
reduction of 16dB.
Release
The Release is the rise time that the Expander/Gate uses to
release the gain reduction when the signal exceeds the
threshold.
Mix
Mixes between direct sound and effect sound.
In Level*
Controls the input level of the block.
Out Level
Controls the output level of the block.
LED Meter
If more than one Dynamics block is present in the Routing,
this parameter determines which one will be displayed by the
Gain reduction meter on the front panel.
Soft Compressor
A Compressor is meant to reduce the dynamic content of the
input signal, and thereby keep a more constant level. When
the input signal exceeds the threshold, the Compressor starts
to reduce the signal according to the Ratio. The Ratio
describes how much the signal is reduced, e.g. a Ratio at 2:1
means that for every 2 dB the signal exceeds the threshold,
only 1 dB comes out.
The Compressor responds to the RMS average level. This
means that if the source signal is very percussive, containing
high peak to average ratio, you probably will not have as
much compression as if the signal had a small peak to
average ratio.
The Compressor uses auto-makeup-gain. This means that the
Compressor automatically compensates for the loss of level
caused by the gain reduction, by turning the out level up i.e.
the more you compress, the higher level you get out.
The Attack time is scaled automatically depending on the
dynamic content of the incoming signal. The parameters
available in the Modifier Matrix are marked with an asterisk*.
SOFT COMPRESSOR
Threshold
When the input level exceeds the Threshold, the Compressor
will be activated. This means that the lower the Threshold,
the more compression you will get.
