libpd-wasm

Run Pure Data patches in browser AudioWorklets with libpd/WebAssembly.

This package is browser-focused. It provides a small TypeScript API plus prebuilt AudioWorklet runtime assets for vanilla Pd, cyclone, ELSE, and a full bundle containing both external libraries.

import { createPd } from "libpd-wasm";
import workletUrl from "libpd-wasm/assets/libpd-worklet.js?url";

const pd = await createPd({
  packages: ["vanilla"],
  files: {
    "patch.pd": patchSource,
  },
  entry: "patch.pd",
  workletUrl,
});

pd.connect();
pd.sendBang("start");

The worklet URL must be served by your browser bundler or app server. With Vite, the ?url import form above serves the file from the installed npm package.
