A brick wall for your master bus.
Blue Cat’s Protector is a 0 dB stereo brickwall limiter with adjustable dynamics response. It is designed 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 it’s custom dynamics histogram provide premium visual feedback. In addition, it the perfect tool to monitor and control the dynamics on your master bus. 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. This is 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, indeed, 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 Main Features: 0 dB brickwall peak limiter and waveshaper. Continuous control of the dynamics response from transparent limiting to colorful distortion. Stereo link control. DC Filter to get rid of DC offset. Large zoomable peak and RMS audio levels and gain reduction meters for optimal monitoring. Loudness boost monitoring. Fully configurable dynamics response histogram. Sidechaining capability: a unique way to perform side chain compression and much more. No latency.
