title: What is the max value for onRmsChanged in RecognitionListener
body: <p>I'm implementing voice to text in android. I want to provide feedback to the user the same way google does with there voice to text. Some type of indication as the sound level dips and peaks</p>
  
  <p>I have values that are coming in on onRmsChanged. In order to map this to a progress bar with a max value of 100 I need to know the max value for onRmsChanged.</p>
  
  <p>But it's not stated anywhere?</p>
  
  <p>How can I show sound level feedback without knowing the max value?</p>
  
  <pre><code>class listener implements RecognitionListener {
          public void onReadyForSpeech(Bundle params) {
