Blue Cat Audio has just announced the release of Protector, a 0dB stereo brickwall limiter plug-in with adjustable dynamics response. It will typically find its place on the master bus of your DAW to protect your audio output from overshoot, limit the general volume and improve the perceived loudness, thanks to a very transparent frequency response.

Despite its very simple set of controls, it offers a wide range of sounds and it is also suitable as a track limiter for more creative effects such as distortion, pumping or heavy limiting.

Beyond its powerful dynamics processing features it also offers a powerful side chain capability thanks to its MIDI CC output. This unique technique not only lets you do side chain limiting but also parameters modulation: control any parameter of any plugin to create powerful side chain effects in real time.

Blue Cat's Protector is available now for Windows in VST and DirectX formats at an introductory price of $74.76/€49.56. Demo versions are available.
