spectral-freeze-wam

Headless Web Audio Module build of Spectral Freeze.

This package ships:

• dist/spectral_freeze_wam.wasm — Rust DSP compiled to wasm32-unknown-unknown
• dist/SpectralFreezeWamProcessor.js — AudioWorklet processor that loads the wasm directly
• dist/SpectralFreezeWamNode.js — main-thread node wrapper
• dist/index.js — package entry point

The WAM is intentionally headless: hosts should call getParameterInfo() and render controls themselves. There is no createGui().

Usage

import SpectralFreezeWam from "spectral-freeze-wam";

const audioContext = new AudioContext();
const node = await SpectralFreezeWam.create(audioContext);

source.connect(node).connect(audioContext.destination);

node.setParameterValue("freeze", 1);
node.setParameterValue("organic", 0.5);

console.log(node.getParameterInfo());

If your bundler needs explicit asset URLs:

const node = await SpectralFreezeWam.create(audioContext, {
  wasmUrl: new URL("spectral-freeze-wam/dist/spectral_freeze_wam.wasm", import.meta.url),
  processorUrl: new URL("spectral-freeze-wam/dist/SpectralFreezeWamProcessor.js", import.meta.url),
});

SharedArrayBuffer requirement

Parameter updates use a SharedArrayBuffer ring buffer, not postMessage, so browser pages generally need cross-origin isolation headers:

Cross-Origin-Opener-Policy: same-origin
Cross-Origin-Embedder-Policy: require-corp
