title: Getting decibel from an Android microphone
body: <p>I have been searching for quite some time now, and I haven't been able to find a way to actually get an SPL/db value from a microphone on Android. </p>
  
  <p>The few threads and articles that I have found that discussed it treated it like something <em>so</em> obvious that anyone should be able to do it, and were more concerned with getting their conversion algorithms correct. </p>
  
  <p>Does anyone know how to do this?</p>
