Audio Filter

vvvv gamma question

Hello,
Could somebody please explain what the Audio Filter input pins are for?
I am trying to create a bandpass filter between 500 and 600 Hz, but not sure how to use CutOff and Resonance.
Thanks!

Here a screenshot of a test with Cutoff Offset 200 and Resonance 10. And this seems to create a tonal frequency around 200Hz with resonances around 800, 1300, 1900, 2500 etc. What would be the logic behind it?

The reason for this is that the Resonance Offset is meant to be a value only between 0 and 1. Since this was not mentioned, i’ve added this information now to the helppatch.

And just in case it helps you, here is the soruce code of the filter: VL.Audio/VL.Audio/src/Signals/Filters/AnalogModelingFilterSignal.cs at main · vvvv/VL.Audio · GitHub
