Finishing a couple thoughts exploring audio tools. Wondering if it would be possible to build an audio filter inside Vuo. Tinkering with the audio tools, having a couple audio filters is a missing link. Be nice to have a 2-pole "state variable" type filter, biquad or otherwise. Low pass/high pass/band pass/notch with frequency/cutoff and Q/resonance. (Shelves would be nice, too). This is a legit feature request, of course, but wondering if possible to put something together with built-in modules?
Thinking of designs like the family of filters known as ZDF filters -- "zero delay feedback" filters -- which cover a range of "virtual analog" style digital filters. A lot of these are not too daunting to get up and running. The question is, is it possible to create the zero delay feedback part at audio rate inside Vuo -- i.e., the integrator. Could I do it with
Enqueue, using the current and previous sampled value? Or is there another way to implement a recursive function? Or can the graph handle a feedback loop, with
Hold nodes or whatever?
Also wondering about audio noise. Any built in noise node translate well to audio?
Edit: white-ish noise is no problem:
Fire at Audio Rate -->
Make Random List (I set count to 512) -->
Convert Real List to Audio.
