Blue Cat's Protector is a 0 dB stereo brickwall limiter with an 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 very transparent frequency response and its lookahead capabilities.

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.

Its large colorful peak and RMS meters and its custom dynamics histogram provide premium visual feedback and make it the perfect tool to monitor and control the dynamics on your master buss. You can also check in real-time the loudness boost obtained with the limiter.

Beyond its powerful dynamics processing features, and like most of our plug-ins, Blue Cat's Protector also offers an original 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.

If you are looking for a complete dynamics processing solution, you might be interested in the Blue Cat's Dynamics plugin. For multi-band limiting and more, check out Blue Cat's MB-5 Dynamix
