title: How to make Mediaplayer's getMaxAmplitude return faster (not zero)
body: <p>For a project i have a lot of trouble with i encountered that the <code>getMaxAmplitude()</code> doesn't always return the real measured value but rather returns a '0' instead. 
  For my project i require to get the sound amplitude 10 times per ms (10.000Hz)
  At least. 
  I put my results in an graph on my app: <a href="https://i.stack.imgur.com/Zv8vB.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Zv8vB.jpg" alt="Graph returning amplitude"></a>
  As you can see my actual sound level is only returned about once every 10-20ms (the pink/red dots are points where i've gotten a returned value). </p>
  
  <p>Has anyone encountered this? Has anyone found a solution for this problem?</p>
