"Remember, the object of these devices are to make your music sound even more professional.[...] Blue Cat Audio doesn’t just make plugins without a reason. While these two are very similar, they work for very specific recording work segments. My opinion is that you want to use the StereoScope Multi when tracking or mixing your tracks and the StereoScope Pro when you are ready to “Master” your audio down to a two-track master! - Glen Heffner, CakewalkNet [Read full review]

"Blue Cat's range also includes a healthy selection of EQs and filters, and their Widening Parametr'EQ is another mastering tool with a twist. It's a stereo equaliser that operates in M/S mode, allowing you to apply different EQ curves to the Mid and Sides components of the signal before they are matrixed back into conventional stereo. [...] I was surprised at how effective the M/S equalisation can be for opening out a mix. A little high shelving boost and low-frequency cut on the Sides channel only can really make things more expansive, without introducing obvious artifacts or leaving a hollow centre, as some stereo width processors do. Sound-wise, the equalisation is transparent without being thin or unnecessarily clinical, and the width of the parametric bands can be set as low as 0.01 octaves, for surgical tasks such as hum removal." - Sound On Sound Magazine - May 2008

The generous offering of a full range of time based modulators consists of very basic but powerful and versatile effects. The Blue Cat Chorus for example, is ALWAYS the first one I try for super rich detuning and haywire coloured effects, but at the same time, I find it can throw just the right wisp of mist into a warm string pad. - Max Debutante

The Blue Cat Frequency Analyst jam packed with different ways to visualize your audio. Sure the standard saying among most sound engineers is "use your ears" but everyone needs a little bit of visual aid. In this case of course it is a lot of visual aid. - Daniel Agosto, Media Producer for gearwire.com - see the video review on gearwire.com

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

Peak Meter...A multitude of uses: for those of you who can't immediately think of too many useful things for peak meter - and initially it didn't make me go "wow" either...but as I sat and pondered it dawned on me what an absolute gem Peak Meter can be - invaluable even:

Make a dynamic reverb out of an ordinary one / Filtering - endless possibilities when applied to filter cutoff / It makes almost a modular synth out of even the most ordinary one / it's the most useable and simplistic gate that anyone who's even a complete beginner can use / Dynamics weirdness / Make a frequency conscious compressor without using a compressor / Kick/bassline ducker too.[...]

The possibilities of Peak Meter are endless, and incredibly useful. It could turn into one of my most used plugins I think...thanks! - Alex Bowers, quoted from this forum thread.

Blue Cat Audio's free plugins have had a staple presence in my arsenal since the first time I came across them. Free or not, these plugins maintain a distinct flavour that makes them my absolute go-to plugins when the situation calls for it.

This group of plugins has the added bonus of full automation and MIDI interfacing, and a standardized configuration template that easily melds them into any DAW configuration. They couldn't be easier to use at any experience level, allow very fine incremental adjustments, and are thoroughly optimized for resource consumption. - Max Debutante

"These analysis plug-ins [...] are available separately if you wish, but the bundle represents a significant saving and the tools on offer are simply amazing. There is just about nothing you can't find out about your digital audio using these analysers, many of which support advanced features [...]. For less adventurous, the plug-ins simply represent extremely acurate and flexible analysis tools." - Hollin Jones, Producer, Music Tech Magazine, July 2010.

"Blue Cat's Dynamics is a very well-specified compander which, with the exception of multi-band capability, offers just about every form of dynamics processing there is, including simulated VCA and opto compression, true downward expansion, gating and limiting. [...] Its strongest suit, to my mind, is the ability to apply both conventional compression and downward expansion at the same time, which is useful if, for example, you have a recording with a wide dynamic range and a lot of background noise.[...] For the price this is a versatile and powerful Swiss Army Knife of dynamics plug-ins." - Sound On Sound Magazine - May 2008

"Looking very much as if it were inspired by Eventide Clockworks' 1970s effects, this terrific freebie comes in a wide variety of plug-in formats and provides a terrific-sounding chorus with a reserved but flexible smattering of controls. A random mode generates presets if you're not inclined to set them up yourself, and both mono and stereo versions are included." - Computer Music Specials [excerpt on musicradar.com]
