title: Stream WAV files in browser without allowing download
body: <p>I'm looking for a way to stream WAV files via a web interface without making the files downloadable (or at least hidden enough in the browser cache they can't easily be found by end users).</p>
  
  <p>The files are recordings of calls within a call center, so due to legal requirements I need to log every time someone listens to a call. This means I must make sure that they can not easily download the file and listen to it later without it being logged.</p>
  
  <p>The files are in g729 format on the server, but I can easily convert them on the fly to wav (or most other audio formats).</p>
  
  <p>I've had a look into HTML5 audio and a few flash based players, but haven't as of yet found anything that doesn't expose the URL of the file.</p>
  
  <p>If anyone could point me in the right direction, it would be very much appreciated!</p>
