title: HTML Audio recording until silence?
body: <p>I'm looking for a browser-based way of <strong>recording until a silence</strong> occurs.</p>
  
  <p>HTML audio recording from the microphone is possible in Firefox and Chrome - using
  Recordmp3js see:

  and the code on github: <a href="http://github.com/nusofthq/Recordmp3js" rel="noreferrer">http://github.com/nusofthq/Recordmp3js</a></p>
  
  <p>I can't see a way to change that code to record until silence.</p>
  
  <p>Record until silence can be done (and tuned) using Java for a native Android App -  see here:
  <a href="https://stackoverflow.com/questions/19145213/android-audio-capture-silence-detection">Android audio capture silence detection</a></p>
  
  <p><a href="http://www.google.com/insidesearch/features/voicesearch/" rel="noreferrer">Google Voice Search</a> demonstrates a browser can doit - but how can I using Javascript?
  Any ideas?</p>
