An AudioWorklet-based Signal Engine
summary
A web-based live coding playground called Sama compiles EBNF grammars into DSP that is injected and dynamically evaluated inside an AudioWorklet-based engine so audio runs on a dedicated thread rather than the main thread. The team refactors and ships a refactored Maximilian.js DSP backend, runs in Chrome, and shows evaluation-to-sound latency under ~20 ms for typical loads. Load testing hits a noticeable spike around 250 oscillators, and the AudioWorklet approach eliminates the script-processor freezes caused by on-main-thread ML training.
