Blue Cat's Widening Triple EQ is the "Widening" (Mid/Side) version of the Triple EQ shapeable filter / equalizer: it is a three bands real time semi-parametric mid/side equalizer. It lets you control the low, medium and high gains of the mid (mono) and side (stereo) components of your audio signal independently, with a custom filter shape. It enables you to manage the wideness of a stereo signal for any frequency. With the ability to control the center of the M-S matrix, it is possible to adjust the spectrum of a sound anywhere in the stereo field.

The plugin provides instant visual feedback of your settings thanks to the included graph. The overlayed controls lets you shape the filter easily. The mid and side channels responses can be linked together in multiple ways (with a mirroring capability) for easier balance of frequencies.

For more information about the core technology of the filters, please read Blue Cat's Triple EQ plugin's description. Additional information about stereo widening and narrowing with mid/side processing can be found in this mid-side processing paper.
