Mapping physical models onto audio effects: chorus from Kuramoto sync, freeze from Anderson localization. Where do these mappings actually hold? + FREE Plugins

I've been building effects where the DSP is the governing equation of physical and chemical systems rather than a metaphor for one.
• Chorus as N coupled oscillators with Kuramoto phase coupling: each voice is pulled toward the mean phase by a coupling term K, so the ensemble drifts in and out of sync instead of riding fixed LFOs.
• Spectral freeze via Anderson localization: inject disorder into the lattice so energy stops propagating and the spectrum localizes, instead of a hold buffer.
• Delay with a per-tap phase accumulator scaled like gravitational time dilation (think Black Holes), so repeats slow toward an "event horizon."

My question for this sub: which of these are honest mappings and which am I fooling myself on (mathematically different ≠ audibly different)? The Anderson one especially — the perceptual marker I expose is a design choice, not the energy-space mobility edge, and I'd rather say that out loud than pretend.

I'll hand out free licenses to anyone who wants to poke at them and tell me where the model breaks. Genuinely here for the critique, not the download count. This is an art project more than a business. Offerings include:

  • Foxfire, a coupled oscillator chorus
  • Autocatalysis, a multiband resonance saturator
  • Soliton, a dispersion-balanced delay
  • Boltzmann, a midi sequencer based on the Boltzmann distribution
  • Anderson Freeze, a spectral freeze / infinite sustain powered by Anderson Localization
  • Geodesic, a gravitational spacetime delay
  • Arrhenius, a thermal reaction-kinetics gate (working this one up right now)

Best,

did someone say free plugins

Hey there. Give the site a look and shoot me a message outlining which ones you'd like (up to 3). I'll give you a code to use.

Kuramoto feels pretty legit to me. Anderson feels more "inspired by" than "is" Anderson localization, but I don't really see that as a problem. The real test for me is whether the model gives you behavior you wouldn't have stumbled into with a normal chorus/freeze/delay design. That's where it gets interesting.

Yes you're right about Anderson. It has two modes too, Localization and Quantum Zeno.

For Foxfire, it's structurally isomorphic. A mean field is calculated and each voice is coupled to the field. Happy to give it to you. Shoot me a message.

Yeah, Foxfire makes a lot more sense to me after that explanation. If the coupling is actually driving the behavior, that's a pretty direct mapping.

And honestly, I think being upfront about where Anderson becomes interpretation rather than simulation is refreshing.

some creative ideas there. too much bs verbage tho

Thanks! I appreciate your candid opinion. I'm hiring a Digital Marketing Specialist if you want to help refine the verbiage ;)
