A brick wall for your master buss
Blue Cat's Protector is a 0 dB stereo brickwall limiter 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. Its large colorful 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 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.
