Blue Cat Audio releases Blue Cat's Protector 2.0 (incl. Win AAX)

Blue Cat Audio has released Blue Cat's Protector 2.0, a complete redesign of its brickwall limiter plug-in for Mac OS X and Windows.

The plug-in is available alone or as part of several bundles.

Demo versions can be downloaded on www.bluecataudio.com, in VST, RTAS, AAX, Audio Unit and DirectX formats (32- and 64-bit).
