Dynamics Effects

Compressor
The Compressor reduces the dynamic range of a sound. This way, the sound gains
headroom. You can use this extra headroom to make the overall sound louder again.
The graphical control to the left indicates the compression curve. You can edit the
Threshold and Ratio value with the handles of this control, the corresponding knobs
reflect your changes. The input and output VU meters indicate the level before and
after the compression. The Gain Reduction meter indicates the current attenuation of
the level.
Threshold
Use this to set the threshold in dB. Sounds that are louder than the threshold are
reduced in gain. Sounds below the threshold stay untreated.
Ratio
This adjusts the amount of gain reduction for sounds that are louder than the
threshold. The higher the ratio, the more the output is lowered. For example, if the ratio
is set to 2:1 and the amplitude of the sound is 4 dB above the threshold, the output is
lowered by 2 dB. If the amplitude is 8 dB above the threshold, the output is lowered by
4 dB.
Soft Knee
If this button is off, signals above the threshold are compressed instantly according to
the set ration (hard knee). When Soft Knee is activated, the onset of compression is
more gradual, producing a less drastic result.
Make-Up
Depending on the set threshold and ratio, the sound loses gain (indicated by the Gain
Reduction meter). You can use the Make-Up parameter to make the overall sound
louder again.
Auto
This calculates the gain loss from the Threshold and Ratio settings and sets the Make-
Up value automatically. The Make-Up knob is disabled when Auto is active.
Attack
This determines how fast the Compressor effect reacts to sounds that exceed the set
threshold. The longer the set Attack time, the longer the period for reducing the gain
to the set ratio will be. In other words, with longer Attack times the onset of sounds
exceeding the threshold pass through unprocessed.
Hold
This sets a time period during which the compression is applied after the sound
exceeds the set threshold.
