Modeling an Analog EQ in HISE

[andrei s]

Hello!
I'm working on a plugin EQ based on an analog device with three knobs. I tried recording an IR for each knob position and combining them in HISE, but the sound suffers from phase issues. Recording every possible knob combination is impractical.
What’s the best way to model an analog EQ in HISE and capture its character without thousands of impulses?

@andrei-s Either a complex transfer function (lots of maths) or a neural model like Wavenet or some of the stuff Christian Steinmetz was doing (also lots of math)

I would suggest Wave Digital models - Faust has a WD library , but you could also do it in C++ with (mentioned above) transfer functions based on the fuctions you want to model.

@Ben-Catman Yep, Faust WD
