6.6 Compressor
The compressor module is a soft knee variable-ratio processor with maximum compression
becomes a limiter.
6.6.1 Compressor Type
Classic: Classic digital compressor design with well known gain follower
Clean: Low aliasing design, gain follower and double level envelope follower
6.6.2 Level Detector
Peak: Classic peak level detector
RMS: Signal level is calculated from RMS value
6.6.3 RMS Window
Selectable RMS window size in ms, 0 - 3000ms, in 0,1ms steps
6.6.4 Threshold
Calibrated in dBFS. If detector level is below threshold level, compression starts to act. Click
and drag handle to adjust the threshold level, additionally press ctrl key to fine tune. Shift
click resets to default value. Double click on the threshold value below opens input window.
-60dB - +12dB in 0.1dB steps
6.6.5 GainStage Type
Modern: Classic digital gain stage design
Vintage: Analog gain stage with thermal noise emulation
Vintage C: Analog gain stage, without thermal noise emulation
6.6.6 Ratio
This controls the compression ratio in the region above threshold, 1 - inf (limiter), in 0.1 steps
6.6.7 Knee
Adjustable
low aliasing
soft knee, knee starts -x dB below threshold and ends +x dB above, 0
- 24dB, in 1dB steps
6.6.8 Attack
Calibrated in ms, adjusts attack time of the compressor from 0 - 1000 ms in 0.001ms steps
Envelope is shown in the response graph on the right side
6.6.9 Hold
Calibrated in ms, adjusts hold time of the compressor from 0 - 2000 ms in 0.001ms steps
Parameter is only used in compressor type “classic”.
6.6.10
Release
Calibrated in ms, adjusts release time of the compressor from 0 - 5.000 ms in, in 0.001ms
steps.
If clean compressor mode is selected release time also effects hold times of double level
envelope follower
Current Envelope is shown in the response graph on the right side
