Hi all, I've been working on naviergrain, a Csound 7 opcode and visual app that connects granular synthesis with a Navier–Stokes fluid simulation. I was exploring if there was anything interesting if you made many enough grain particles and moved them like fluid in space. Also got inspired by the recent millennium problem solution announced by OpenAI which piqued my interest. Each visible particle is a sounding grain. The app uses cosine carriers with Hann envelopes, with height setting frequency, horizontal position setting stereo pan, and speed affecting grain duration. The solver runs on a periodic 2D grid. An artistic mapping places the particles in 3D space. You can try it in your browser. There's also a standalone osx binary, plus native plugin and a WASM build of the Csound plugin. The opcode can granulate sample tables too. I welcome feedback, and may decide to change it inside out entirely if I notice more interesting sound mapping options. |

Sounds really interesting stuff. I will have a look.
