Description

Blue Cat's Protector - Brickwall Limiter Plug-in (VST, AU, RTAS, DX)

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.

If you are looking for a complete dynamics processing solution, you might be interested in Blue Cat's Dynamics plugin.

Typical applications: master output protection, master buss limiting, loudness maximizing, peak overshoot monitoring, distortion, clipping.

User Comments & Reviews

Blue Cat's Protector was granted the Performance and Value awards by Computer Music Magazine

Used on the master bus, it catches loud incidental peaks and transparently softens them, preventing nasty digital clipping without the need to turn the volume of your entire project down.[...] But Protector has many other tricks up its sleeve [...]. As a mix effect, Protector has just as many creative uses as it does purely practical ones [...], offering anything from brickwall-style peak limiting to violent waveshaping when used with very fast times. [...]

The Stereo Link control facilitates both linked and unlinked operation, as well as any point in between.[...] The plug-in doesn't introduce latency, and requires an insignificant amount of processor power, so stacking multiple instances is no problem.

All of which means that it's a thumbs up from us.

"Verdict: More than a mere limiter, Protector has quite a range of applications. What's more, it sounds great and is very keenly-priced." - 9/10 rating and performance and value awards granted by Computer Music Magazine (CM), October 2008 - www.computermusic.co.uk - [read review on musicradar]

After trying Protector, I dare say this is one of the most transparent limiters I've tried to date! This limiter is a perfect addition to the Blue Cat Audio lineup - great work! - Jeremy Dahl, audiogazette

I tried out the demo and after just a few minutes I went back and bought it!

The Blue Cat Audio stuff is always quality, and the prices are more than reasonable - especially with the discount for being a previous customer! - Kevin Demuth, musician/composer

Bought it. Very nice! Does the job perfectly! It's very transparent, even at lower threshold settings. And the lovely level meter is the big bonus! Great plug! I used it to raise the RMS volume of a couple of my field recordings in OS X recently. - Andrejs Eigus, selffish
