WebAssembly AudioWorklet Csound

on YouTube ↗20m

" summary

A WebAssembly + AudioWorklet Csound port runs LibCsound in an AudioWorklet node with a ScriptProcessor fallback, shipping both sync and async WASM loaders. It powers live coding on live.csound.com and a reverb demo using two FFTs (one per channel) with pitch shifting and feedback, and runs on phones (Motorola G) and desktop. Performance sits around ~50% native speed, audio worklet reduces glitches but occasional dropouts link to GC and thread-priority issues, and packaging requires extra build care.
