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...

Oscillators:

without sounds as they can be ear piercing and I have to figure out HTML 
to set the player to a low volume.

But you can render the sounds yourself,

That's intersting!

Good idea to probe the surface in a circular motion so that there are no
discontinuities in the sound wave.

Properly closed splines also work well,

Audacity has function 'Sample data import' that I've used to make my own waves.
It is written in a float txt format that makes it eazy to import from POV.
I use POV splines to make a road height field and then used the same splines to
make the motor noise of a car.(it's on YouTube as MarsCarsII)

I like what you've done! Keep up the good work.

Didn't know that one, can be useful.
Those martians live dangerously on the wrong side of the road.
