EQ1979 is a stereo VST analog console strip emulation inspired by a famous British console module with red gain knob.
EQ1979 has three stages:
Input Driving stage, which emulates a transformer based analog input amplifier with smooth saturation.
Filtering stage with low shelf, mid band, and high shelf inductor-based filter emulation
A Third order highpass filter emulation
Technology
Input saturation uses a subtle combination of arctangent and polynomial math to first boost 3rd and 5th harmonics while increasingly switching to a full spectrum asymetrical saturation. Loudness partial compensation is linear.
Filtering uses a combination of more than 50 butterworth maximally flat one pole filters to frequency match the existing console strip behavior. A fine-tuned parametric model dynamically parameters those filters upon console strip inputs.
Modeling accurately the lectronics implied adding several asymetrical bias, noise sources and non linearities which tend to reproduce the unique analog console sound.
Part of modeling that real console behavior, even filter idle states trigger frequency response variations, as shown here
Installation
Windows : Extract archive to your VST3 folder (default c:\program files\common files\VST3)

Changelog:
1.02 Bugfixes and user feedback implementation
Fixed a bug on High Shelf response stereo diffrerence,
Added a control to passivate internal electronics noise simulation to avoid noise stacking on projects with multiple instances involved
Anti-aliasing filter frequency tied to 0.48x sampling frequency to allow projects with greater sample rate to take benefit from a broader high frequency range.
Added control readouts for Drive and Gains controls
Added mouseover hints on every control1.01 Fixed pairing stereo outputs
