Hi everyone,


I wish I could have an all pass filter block with voltage control on frequency on Sigma Studio Library for a guitar phaser project

with Aida DSP.

So I've made a 1st order IIR filter path and I'm wondering if it's correct in theory. I've tested it a bit and it doesn't work as expected.

Basically I need to calculate only b0 coefficient, while a1 it's b0 inverted. It's a very simple project, however it seems don't work.




Any suggestions?
