Okmog – Gyrator X v2.0.5 VST3, AAX x64
Gyrator X is a next-generation equalizer built on a fundamentally different approach to digital signal processing. Developed by physicist and master engineer Oliver Graetz, Gyrator X goes beyond traditional DSP methods by modeling the real electrical behavior of analog circuits and delivering a level of realism, responsiveness, and musicality rarely achievable in the digital domain.
An equalizer based on physical laws and real circuits.
From the physics lab to your DAW.
For decades, digital equalizers have attempted to recreate the sound of analog devices, but they often lacked something crucial: the physical interactions between components that give real-world circuits depth, dynamics, and musical expression.
The Gyrator X was created to solve exactly this problem.
Developed by physicist, circuit designer, and producer Oliver Graetz, Gyrator X eschews conventional digital signal processing techniques. It’s a physics-based, topology-preserving emulation of analog circuits, modeled at the component level and brought to life through years of research, measurement, and listening.
The result is an equalizer that responds organically to changes, sounds musical, and integrates naturally into professional mixing and mastering workflows.
“Curve precision was never enough. I needed the responsiveness, interaction, and musicality that only real circuits provide. The Gyrator X is the result of years of research into how these circuits actually behave.”
