A Physics-Driven Equalizer Derived from Real Circuits
From the Physicist’s Bench to Your DAW
For decades, digital equalizers have sought to recreate the sound of analog hardware. Yet something essential has often been missing: the complex interaction between electronic components that gives real circuits their depth, movement, and musical character.
Gyrator X was created to capture exactly that.
Developed by physicist, circuit designer, and producer Oliver Gretz, Gyrator X goes beyond conventional DSP techniques. It is a topology-preserving, physics-based simulation of analog circuits, modeling the behavior and interaction of individual components with exceptional accuracy. The result of years of research, measurement, and critical listening, it recreates not only the frequency response of classic analog designs, but also their dynamic behavior and musical feel.
The result is an equalizer that responds naturally, feels intuitive, and integrates seamlessly into professional mixing and mastering workflows.
“Matching the frequency curve was never enough. I wanted to recreate the responsiveness, interaction, and musicality that emerge from real analog circuits. Gyrator X is the culmination of years of research into how those circuits truly behave.”
— Dr. Oliver Gretz
