disPRESSA is a distortion powered compressor. It's not a normal math modelled compressor - no threshold, ratio, or knee controls. Instead, disPRESSA uses overdrive as its method of compression. The input channel is overdriven and then measured. Its level is then used to set the level of the clean output channel. The more distortion is piled on, and the higher the contour control, the more the signal is compressed.
It has controls for:
- Sidechain Filter.
- Distortion model.
A mono version of disPRESSA is available for free (the full version is stereo).
