On: Wavacity – a FOSS port of Audacity to the web

Can anyone summarize how this works. Guessing Audacity is some C++ program. How did they take all the dependencies and make them work on browser, using WASM? What about the frontend? Is the UI just completely re-written?

I think so. They use Emscripten to compile.

Remarkable.

It uses wxwidgets so they can just compile that to webassembly too.

wxWidgets uses native controls, so just compiling to "WebAssembly" (I'm assuming it's compiled to WebAssembly, plus some JavaScript for DOM manipulation) was probably a significant amount of work. I'm actually curious how it was done!
