Blue Cat's Stereo Parametr'EQ

"The best of both worlds, in stereo!"

Blue Cat's Stereo Parametr'EQ is a 7 bands parametric stereo equalizer based on Blue Cat's Parametr'EQ technology, providing the best of the analog and digital worlds in stereo.

This stereo plug-in enables you to manage separately the left and right equalizer settings and keep an eye on both frequency responses thanks to the frequency graph above the controls. The left equalizer is visible by its blue color and the right equalizer controls and graph are red. Left and right controls can be linked together with several modes. The Smooth Update and Smooth Bypass technologies have been included in this plug-in so that you can automate the equalizer in your favorite sequencer or use the MIDI capabilities of your host software to control the EQ in real time. You will get an absolutely zipper-free continuous time-varying equalization. These capabilities and the zero latency of this plug-in make it suitable for any real time application.

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