Pulsatec is a modern equalizer plugin designed to capture the essence of vintage passive EQs, offering a warm, musical tone that enhances the character of any audio source. Its design allows for simultaneous boosting and attenuation of the same frequency range, enabling unique tonal shaping techniques that have been cherished by audio professionals for decades.

The plugin provides intuitive controls for low and high-frequency bands, each with selectable frequencies and adjustable bandwidth. This flexibility ensures precise sculpting of the audio spectrum, whether you're aiming to add punch to the low end or clarity to the highs. The ability to fine-tune these parameters makes Pulsatec a versatile tool for both mixing and mastering applications.

Complementing its sonic capabilities, Pulsatec features a built-in Real-Time Analyzer (RTA) that offers immediate visual feedback on frequency response changes. This integration facilitates informed decision-making during the mixing process, allowing users to see the impact of their adjustments in real-time.

Additional features like quick bypass, output volume control, and output metering seamlessly blend classic tonal qualities with modern functionality.
