An equalizer based on physical principles and created using real circuits.Description
For decades, digital equalizers have attempted to recreate the sound of analog equipment,
but they’ve often missed something essential: the physical interactions between components that give real-world circuits depth,
movement, and musical response.
The Gyrator X was created to solve exactly this problem.
Developed by physicist, circuit designer, and producer Oliver Graetz, the Gyrator X doesn’t use standard DSP techniques.
It’s a topology-preserving, physics-based emulation of fully analog circuits, modeled at the component level
and brought to life through years of research, measurements, and listening tests.
The result is an equalizer that responds organically, feels musical, and integrates naturally
into professional mixing and mastering workflows.
Key Features
Gyrator-based EQ core
• Low, mid, and high frequencies derived from gyrator analog circuitry
• Authentic analog component interaction
• Carefully tuned frequency ranges and Q-factors to shape music
• Independent mid/side or left/right control
Signature Sky Band
• Patented high-frequency driver design delivers open, airy sound without harshness
• Multiple response modes provide subtle or sustained brilliance without unnaturally altering the spectral balance
Advanced Filter Section
• High- and low-pass filters based on classic analog circuits
• Multiple circuit types including:
– Multiple Feedback (MFB)
– Switched Switch (SK)
– State Variable Feed (SVF) (including 4-pole SVF)
– Passive high-pass design
– Proprietary gyrator-based low-pass converter
• Circuit-dependent behavior
Two ADAA Saturation Stages
Two completely independent saturation stages using the Anti-Derivative Anti-Aliasing (ADAA) function,
with several models developed from detailed analog circuit measurements for precise harmonic control.
The following saturation models are available:
– Modern Vacuum Tube
– Vintage NOS Tube
– Silicon and Germanium Transistor Stages
– Silicon and Germanium Diode Circuits
– Class A JFET Stage
Each stage can be freely positioned within the signal path, allowing precise
tonality shaping before or after the EQ stages.
Precise workflow and control
Fully interactive interface
• Dual-channel control (left/right or middle/side)
• Ability to connect or independently adjust parameters
• Expandable, high-resolution user interface,
• optional visual spectrum analyzer and EQ curve display
Advanced Controls
• A/B State Comparison
• Undo/Redo History
• Automatic Gain Compensation
• Optional Oversampling (including Render-Only Oversampling)
• Multiple UI Themes and Contrast Modes
Spectral Analysis and Visualization
• Real-time FFT display with adjustable speed and slope
• Optional EQ curve overlay
• Individual control of analyzer and EQ display range
