Blue Cat's Parametr'EQ is a 7-band parametric equalizer that merges the best aspects of digital precision and analog character. It offers a flexible sound shaping experience, allowing users to simulate analog compression and distortion or achieve a clean and transparent digital equalization. This balance helps producers and engineers tailor their sound with warmth or clarity as desired.

The plugin features a true WYSIWYG interface and supports single, left/right, or mid/side dual channel modes, making it adaptable for various mixing scenarios. Each band provides a wide gain range and customizable settings, with filters inspired by analog circuitry. Non-linear modeling adds warmth and subtle distortion, while oversampling and a brickwall limiter ensure high-quality output without latency.

Designed with performance and usability in mind, Parametr'EQ includes real-time frequency response display with zooming, automatic gain compensation, and smooth parameter updates to avoid audio artifacts. It supports full automation and advanced MIDI control with learn functions for dynamic adjustments. The skinnable interface and window opacity control further enhance the user experience across all sample rates.
