title: decodeAudioData HTML5 Audio API
body: <p>I want to play audio data from an ArrayBuffer... so I generate my array and fill it with microfone input. 
  If I draw this data on a canvas it looks like --> 
  <img src="https://i.stack.imgur.com/Bhb8Q.png" alt="enter image description here"></p>
  
  <p>So this works!</p>
  
  <p>But if i want to listen to this data with</p>
  
  <pre><code>context.decodeAudioData(tmp, function(bufferN) { //tmp is a arrayBuffer
      var out = context.createBufferSource();
      out.buffer = bufferN;
      out.connect(context.destination);
      out.noteOn(0);
  }, errorFunction);
  </code></pre>
  
  <p>I dont hear anything... because the errorFunction is called. But error is null!</p>
  
  <p>I also tryed to get the buffer like that:</p>
  
  <pre><code>var soundBuffer = context.createBuffer(myArrayBuffer, true/*make mono*/);
  </code></pre>
  
  <p>But i get the error: Uncaught SyntaxError: An invalid or illegal string was specified. </p>
  
  <p>anybody who can give me a hint ?</p>
  
  <p><strong>EDIT 1 (More code and how I get the mic input):</strong></p>
  
  <pre><code> navigator.webkitGetUserMedia({audio: true}, function(stream) {
  
                  liveSource = context.createMediaStreamSource(stream);
  
                  // create a ScriptProcessorNode
                  if(!context.createScriptProcessor){
                     node = context.createJavaScriptNode(2048, 1, 1);
                  } else {
                     node = context.createScriptProcessor(2048, 1, 1);
                  }
  
  
                  node.onaudioprocess = function(e){
  
                 var tmp = new Uint8Array(e.inputBuffer.byteLength);
                 tmp.set(new      Uint8Array(e.inputBuffer.byteLength), 0);
  
     //Here comes the code from above.
  </code></pre>
  
  <p>Thanks for your help!</p>
