title: What is the unit of the returned amplitude of getMaxAmplitude method?
body: <p>Does anyone know what is the returned unit of the method:</p>
  
  <pre><code> MediaRecorder.getMaxAmplitude();
  </code></pre>
  
  <p>The Android MediaRecorder API documentation indicates only that this method returns the maximum absolute amplitude of the sampled points since the last call but does not specify the unit. Is it in pascal, milli-pascal, other?</p>
