Amp Up Web Audio Applications with Rust and WebAssembly
summary
Rust compiles to WebAssembly to run real‑time DSP in the browser, producing a working sample player and TV303‑style synth and showing 15–20% less CPU than the JavaScript equivalent in casual profiling. The build uses raw WebAssembly modules, the Web Audio API’s Audio Worklet requires fetching the module and posting binary to the worklet and shared memory setup is fiddly; threading still relies on WebWorker sequencing and Audio Worklet is currently Chrome/Opera only.
