CBiquad, CEnvelopedetector (pluginconstants.h) missing | Installing and Using RackAFX7 | Forum

Hello!

I use RackAFX Version 7.0.2.3 together with the book "Designing Audio Effect Plug-ins in c++" from 2013.

I try to implement the EnvelopeFollower project, which requires declarations of

CBiquad m_LeftLPF 

among other variables.

 

But CBiquad seems to be missing. I also don't find pluginconstants.h.

Googled it and found pluginconstants.h in some other person's git. But using it led to other errorrs.

How can I make filters using CBiquad and CEnvelopeDetector work?

Kind Regards,
