What SSi Pro Compressor does
The plugin is built around a high end sound engine and an analogue-modelled tube gain section, and its controls cover attack and release, threshold, ratio, gain, range, knee, RMS detection and hold. Presets are included to get started, and the developer describes the GUI as professionally designed and laid out around the user. A trial is available.
Key features
- Tube gain stage. An analogue-modelled tube gain section adds coloration to the compressed signal, and its drive sits alongside the main compression controls.
- Attack and release. Attack and release times shape how quickly the compressor responds to the input and how fast it lets go.
- Threshold, ratio and knee. Threshold, ratio and knee set where gain reduction begins, how strongly it acts above the threshold, and how gradually it engages.
- Gain and range. Make-up gain restores level after reduction, and a range control limits how far the compressor is allowed to reduce gain.
- RMS and hold. RMS detection changes the level averaging used for gain reduction, and a hold control keeps the reduction in place for a set time.
- Low CPU design. The developer lists low CPU usage, which the developer states allows multiple instances to run at the same time.
Compatibility
It works in Ableton Live, Cubase, Nuendo, FL Studio, Reaper, Studio One and Bitwig.
