Blue Cat's Widening Parametr'EQ is a 7 bands parametric Mid-Side equalizer based on Blue Cat's Parametr'EQ algorithms, enabling you to widen or narrow the frequencies of your choice.

This special 'widening' version offers two independent equalizers for the mid and side channels with instant frequency response display. But Blue Cat's Widening Parametr'EQ is much more than a standard mid/side equalizer, since it lets you choose the position of the virtual center for the Mid/Side matrix: you can really control where you want the equalization to take place in the stereo field. You can thus use this parametric mid/side equalizer for many purposes: from simple standard equalizing anywhere in the stereo field to advanced multi-band stereo widening or narrowing.

The new non linear behavior and the included M/S output brickwall limiter will also let you modify the dynamics response of this very special plugin.

For more information about the Parametr'EQ technology, please read Blue Cat's Parametr'EQ plugin's description.

Additional information about stereo widening with mid/side processing can be found in our M/S processing paper.

User Comments & Reviews

"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
