const stream = await navigator.mediaDevices.getUserMedia({audio: true});
const context = new AudioContext();
const microphone = context.createMediaStreamSource(stream);
await context.audioWorklet.addModule('/voiceRecorderProcessor.js')
const recorder = new AudioWorkletNode(context, 'recorder');
recorder.port.onmessage = e => {
  realTimeWorker.postMessage({cmd: 'encode', buf: e.data});
}
microphone.connect(recorder);
recorder.connect(context.destination);

// voiceRecorderProcessor.js

class Recorder extends AudioWorkletProcessor {
  constructor() {
    super();
  }

  process(allInputs) {
    // allInputs has always latest value, but their belongs to same refenrences.
