Convert AudioBuffer to ArrayBuffer

Question

I have searched all over the Internet for the answer to this question, and I cannot find any resources. Does anyone know how to use JavaScript to convert and an AudioBuffer object to an ArrayBuffer? This is my current attempt.

//Send audio data to websockets server function callback(stream) { var ws = new WebSocket("ws://localhost:8080"); ws.binaryType = 'arraybuffer'; var context = new webkitAudioContext(); var mediaStreamSource = context.createMediaStreamSource(stream); console.log(mediaStreamSource); var request = new XMLHttpRequest(); request.open('GET', 'http://s3.amazonaws.com/fldrMusic/01_-%20Fire%20Walker.mp3', true); request.responseType = 'arraybuffer'; console.log("Current 'request.response' value"); console.log(request.response); request.onload = function() { context.decodeAudioData(request.response, function(buffer){ console.log("sent message"); console.log(buffer); ws.send(buffer); //Serialize javascript object console.log("sent message encoded"); var buff = Base64Binary.decodeArrayBuffer(buffer.toString()); console.log(buff); }, function(buffer){ alert("decode failed!"); }) } request.send(); }//end 'callback' function

 AudioBuffer.getChannelData(channel_number); 

You can get the number of channels from AudioBuffer.numberOfChannels

EDIT:
For more information, you can check the MDN docs for AudioBuffer and getChannelData .
