while I'm not able to relate the visual (HF with circles) to the sound played,
this is very interesting stuff. more please. :-)
regards, jr.

Bravo, this is super cool! My mind is spinning with all sorts of applications!
Thanks for this, I look forward to reading more :)

How about the sound of Ken Perlin and a Klein Bottle?

Ingo, I did notice when trying out your code just now that in your files you
use:
#version 3.7;
But when I rendered with the v3.7 executable it choked, which confused me for a
moment until I realized you're using the new v3.8 keyword tau.
It renders as expected with the v3.8 executable so to prevent confusion you
might want to change that to:
#version 3.8;
Again, excellent work!

Perlin Noise, Simplex Noise, or a Perlin smooth-stepped function? ;)
https://en.wikipedia.org/wiki/Smoothstep#Variations
The Klein bottle sounds interesting, as does a Moebius strip.
I am thinking that I'd like to see a "simple" spline-driven song as an
animation, with sheet music. Likely jr would love to see animated media musical
notes.
I find this extremely interesting, because one of the ideas I had about the FFT
was to analyze sound files, identify notes, and then do what you're doing.
What do you think about a POV-Ray modeled phonograph, with a vinyl album made
from a heightfield? The grooves could be a spiral function. :)
Or an old Edison wax cylinder phonograph.

uach. good catch. Mmm as 3.8 isn't out I'll stick to 3.7 and adjust the
scenes for that.
Thanks

the noise generator option 3.

I tried both in SuperCollider and the Bottle does interesting thing. More
than I expected in just noise. The strip I have to try again with swapped
uv coordinates. It was just verry noisy.

Haha, go ahead. I'm not a musician. When I look at a piano it quickly
goes out of tune :)

Kind of the opposite of FFT is an intersting one. Massive additive
syntesis of sine waves. Check the ANS synthesizer. I have a basic
experiment working but have to extend that a lot more. Check
https://warmplace.ru/soft/ans/#about for what can be done. A goal for me
would be to create a collection of snippets of texture on a disc object
or polygon that can be placed in the scene and rendered to sound.

Then there's using splines as envelope's Attack Decay Sustain Release
(ADSR). You can use textures with tracks for rithmic patters. Extend that
idea to sequencers.
And before you know you are knee deep in DSP terretory with FIR filters
etc. https://www.musicdsp.org/en/latest/index.html

what would the Umbilic Torus sound like? :-)

a "modular synthesizer" include, combined with a "recording studio" include,
would make a nice base for exploration. anyway, please keep us in the loop on
developments.

Haha, yeah, well, have a look at VCV Rack https://vcvrack.com/ for that. I
actually wrote a few modules for it, but you'd have to compile them your
self. https://github.com/Moaneschien/4rack

Another great software for programmatic sound making
is Chuck : https://chuck.cs.princeton.edu/
And a few month ago, I'v tried to make some vidz from
sound files, with some gory software. Sorry, this is
in french, but I can translate a few explanation...
