You can pipe a microphone directly to AudioWorklet, using MediaStreamAudioSourceNode. Do the following in the main scope, then you can access the mic input as the input parameter of process() in the worklet scope.

const audioCtx = new (window.AudioContext || window.webkitAudioContext)()
const micStream = await navigator.mediaDevices.getUserMedia({ audio: true })
const micNode = new MediaStreamAudioSourceNode(audioCtx, { mediaStream: micStream })
micNode.connect(yourAudioWorkletNode)
yourAudioWorkletNode.connect(audioCtx.destination)
