CQ1 is a multi-band frequency-selective dynamics processor that offers independent control over four adjustable filter bands. Each band can be compressed or expanded separately, providing precise shaping of audio signals. Unlike conventional multi-band compressors focused mainly on mastering, this plugin employs dynamic equalisation to handle a wider variety of audio tasks effectively.

The processor supports both upward and downward dynamic operations, allowing flexible control above or below the set threshold. Its advanced side-chain filtering enables any frequency to serve as a trigger, enhancing creative possibilities. CQ1 operates with zero latency, ensuring real-time processing without delay, and maintains 64-bit floating point precision internally for high-quality audio performance.

Built using a physical modeling approach, CQ1 delivers an authentic analogue response that enriches sound character. It is optimized for native processors to ensure efficient performance and supports sample rates up to 192 kHz. Compatible with most formats on both Mac and PC platforms, this plugin is designed to integrate smoothly into diverse production environments.
