Javascript converter to .wav

Question

I'm in need of a way to convert my code to .wav and I can't seem to figure out where. I have an audio script that records from the microphone and is saved as so:

const audioBlob = new Blob(audioChunks);
const audioUrl = URL.createObjectURL(audioBlob);
const audio = new Audio(audioUrl);

Is there any way I can use any of these libraries to convert the audio to .wav? If you need any more info let me know. how the audio chunks are encoded:

const audioChunks = []
mediaRecorder.addEventListener("dataavailable", event => {
    audioChunks.push(event.data);
});
