Description:
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 digital signal processing techniques by modeling the real electrical behavior of analog circuits, delivering a level of realism, responsiveness, and musicality rarely achieved in the digital domain.
An Equalizer Based on Physical Laws and Real Circuits
From the Physics Lab to Your DAWFor 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 circuits their depth, dynamics, and musical expression.
Gyrator X was created to solve precisely this problem.
Developed by physicist, circuit designer, and producer Oliver Graetz, Gyrator X eschews standard 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 seamlessly integrates into professional mixing and mastering workflows.
“Curve precision was never enough. I needed the responsiveness, interaction, and musicality that only real circuits provide.” Gyrator X is the result of years of research into how these circuits actually behave.” — Oliver Graetz, Ph.D.
Key Features:
Gyrator-based EQ
Low, mid, and high frequencies modeled after analog gyrators
Authentic interaction of analog components
Carefully tuned frequency ranges and Q values to shape musical sound
Independent operation of mid/side or left/right speakers
Signature Sky Band
Patented high-frequency sound shaping design delivers an open, airy sound without harshness
Multiple response modes allow for subtle sparkle or extended shine without unnaturally altering the spectral balance
Expanded filter section
High- and low-pass filters modeled after classic analog circuits
Several circuit types, including:
Multiple Feedback (MFB) Filter
Sallen-Key (SK) Filter
Filter State Variable Filter (SVF) (including a true 4-pole SVF)
Passive High-Pass Filter
Proprietary Gyrator-based Low-Pass Filter
True Circuit-Dependent Behavior
Two ADAA Saturation Stages
Two completely independent saturation stages using Anti-Derivative Anti-Aliasing (ADAA), with multiple models derived from detailed analog circuit measurements for precise harmonic control.
Available saturation models include:
Modern Vacuum Tube
Vintage NOS Tube
Silicon and Germanium Transistor Stages
Silicon and Germanium Diode Stages
Class-A JFET Stage
Each stage can be freely moved along the signal path, allowing precise tone shaping before or after the EQ stages.
