Support blob URLs in AudioWorklet addModule

[Copilot]

AudioContext.audioWorklet.addModule() supported inline data: URLs and filesystem paths, but rejected blob: URLs commonly produced by bundlers and browser-compatible libraries.

• Module loading

  • Detects blob: URLs in AudioWorklet.#readModule()
  • Reads module source with fetch(url).text() before evaluating in the worklet scope

• Coverage

  • Adds an AudioWorklet test that registers a processor from a Blob object URL

const url = URL.createObjectURL(new Blob([processorCode], {
  type: 'text/javascript'
}))

await context.audioWorklet.addModule(url)
