FaustWasm is a TypeScript‑focused library that wraps the Faust DSP compiler compiled to WebAssembly, letting developers compile Faust code directly in Node.js or browsers and use the resulting modules as WebAudio nodes or offline processors. It provides high‑level APIs for creating mono, polyphonic, and MIDI‑enabled audio nodes, generating SVG diagrams, and packaging DSPs as Progressive Web Apps, targeting web audio developers and educators who want to integrate real‑time DSP synthesis into web applications.
