我有用electron 透過desktop-capturer 把喇叭聲音跟影像錄起來
但是麥克風的聲音不曉得怎麼處理~
請問有大大知道要怎麼把麥克風聲音加進去stream 嗎>?

原理把麥克風輸入的音訊直接撥放出來，然後用MediaRecorder api就可以錄下來了

<audio id="player" controls></audio>
<script>
 const player = document.getElementById('player');

 const handleSuccess = function(stream) {
   if (window.URL) {
     player.srcObject = stream;
   } else {
     player.src = stream;
   }
 };

 navigator.mediaDevices.getUserMedia({ audio: true, video: false })
     .then(handleSuccess);
</script>
