Hi,
I try to understand the code of the [vcf~] filter.
Is there any paper or discussion somewhere that could enlighten me about the mathematics used? For instance what kind of filter is it *precisely*. A one-pole resonant filter (as it is noted in the Puckette's book)?
Note that i'm not an expert at all in that kind of things.
Hi, i recently coded it in more 'readable' c++ code. Can share with you if u want, i guess?
It's a "one pole complex filter", and miller has suggested previously on this list that it is indeed basically a wrapper for the same code as the cpole~ object, with some other stuff thrown in to calculate the coefficients. ( https://lists.puredata.info/pipermail/pd-list/2014-07/107391.html )
cheers, Matt
Yes, I would be very pleased to read your C++ code. And thanks for the helpful link.

Hi there, sorry to raise a dead post..
I'm curious, did you ever end up posting your version of the cpp code somewhere? I'd love to see it if so and try to glean what I can from it.
cheers, Rich
