Blue Cat's Parametr'EQ - WYSIWYG Parametric Equalizer Plugin (VST, AU, RTAS, DX)

Blue Cat's Parametr'EQ is a 7 bands parametric equalizer combining the advantages of both the digital and analog worlds. Its special non-linear and oversampling features let you easily simulate the compression and distortion that may occur in an analog EQ or on the contrary obtain a very clean and transparent digital EQ.

The plug-in includes a low shelf/low cut filter, a high shelf/high cut filter and 5 boost/cut band filters. An optional brickwall limiter has been added to the output to protect your ears and monitors. Its wide range of gain (+/-40 dB per band) and bandwidth (one hundredth to five octaves) makes it suitable for any equalization task, especially with the extra zooming capability that lets you define your own range for the user interface. The included skins let you choose the layout that best suits your needs, and you can completely customize the user interface thanks to Blue Cat's Skinning language support.

The graph displays the computed frequency response of the plug-in, so that you can exactly know how your signal is processed. This is not an approximated or "ideal" response curve based on the controls of the user interface, but the exact computed frequency response of the filter, which makes this plug-in a true WYSIWYG (What You See Is What You Get) equalizer.

Thanks to the included Smooth Update technology, every single parameter of this equalizer can be automated in your favorite sequencer or controlled by MIDI in real time (MIDI learn included). You will get an absolutely zipper-free continuous time-varying equalization. Filters activation and bypass functions are now totally smooth and won't damage your ears or speakers.

Last but not least, this equalizer has absolutely no latency, which make it perfect for real time applications.

This version is a mono effect, which means that you will get the same effect on left and right sides of your audio signal. You may also want to check the Stereo Parametr'EQ plugin or Widening Parametr'EQ plugin for more advanced control on the stereo channels.

User Comments & Reviews

Upon first playing with the plug-in it sounded much like the v2.1 that we had installed. Not much of an audible change was a good thing considering I liked the quality of the ealier version. Next I turned to the Non-Linear and Comp-Dist controls to see if I could dirty up this clean sounding EQ.

I was really impressed with the amount of warmth that could be added with this control coupled with the low shelf.(...)

The limiting and oversampling are also welcome new features. Overall I am excited to work more with this plug-in in a mix. - Daniel Agosto, Media Producer - gearwire.com
