javascript
if (window.AudioContext) {
let audioContext = new AudioContext();
let source = audioContext.createMediaStreamSource(navigator.mediaDevices.getUserMedia({ audio: true }));
let analyser = audioContext.createAnalyser();
let bufferLength = analyser.frequencyBinCount;
let dataArray = new Uint8Array(bufferLength);
let sourceData = new Uint8Array(source.numberOfChannels());
sourceData.set(new Uint8Array(source.sampleRate * bufferLength));
