title: AudioInputStream for AudioPreProcessor
body: <p>I'm working with comirva library and trying to implement <em>getAudioPreProcessor</em> method that takes the file and gets the InputStream. The problem is that Android doesn't support AudioSystem nor AudioInputStream. There is a class implemented in comirva <strong><em>AudioPreProcessor</strong> (constructor: AudioPreProcessor(AudioInputStream in) )</em>, which I need. How can I implement a method to send AudioInputStream type in Android? 
  Hope my question is clear. Thanks.</p>
