The Sonoris Mastering Compressor is a wideband mastering compressor in VST VST3 AU and AAX format for Windows and Mac. It is an ultra clean compressor suitable for delicate material.

Transparency

No odd harmonic distortion that can be found in most compressors is present in the SMCP. To reduce residual artifacts the SMCP features upsampling of the audio up to 8 times. Transparency can be further enhanced by selecting auto-release and feedback detection together with two soft knees.

Character

If a more aggressive behavior is needed you can choose feedforward detection with a harder knee. It can have some character if pushed. If needed the audio can be warmed up by even harmonics with the flip of a switch.

Focus

Besides working on a full mix the SMCP can also work in split mode on the individual L R M or S channels or anything in between with the variable link.

Flexibility

The sidechain for each channel has a selectable high-pass band-pass and low-pass filter. This gives great flexibility and allows for creative enhancement of the audio.
