title: How can javascript upload a blob?
body: <p>I have a blob data in this structure:</p>
  
  <pre><code>Blob {type: "audio/wav", size: 655404, slice: function}
  size: 655404
  type: "audio/wav"
  __proto__: Blob
  </code></pre>
  
  <p>It's actually sound data recorded using the recent Chrome <code>getUerMedia()</code> and <a href="https://github.com/mattdiamond/Recorderjs" rel="noreferrer">Recorder.js</a></p>
  
  <p>How can I upload this blob to the server using jquery's post method? I've tried this without any luck:</p>
  
  <pre><code>   $.post('http://localhost/upload.php', { fname: "test.wav", data: soundBlob }, 
      function(responseText) {
             console.log(responseText);
      });
  </code></pre>
