Practical Rust for Web Audio
summary
Documents building a low level web audio engine in Rust and what actually worked: Rust compiles into WebAssembly but initial builds bloat to 1.3 MB initial WASM bundle until link time optimization wasm‑strip and shrinker trimming cut size; processing runs inside an AudioWorkletProcessor in Rust with data passed via shared array buffer to avoid GC pauses; allocations happen once in the constructor using tiny allocators like mini‑alloc or tal; the result meets the ~128 frame / ~2.6 ms render quantum and yields predictable realtime processing.
