title: Apply echo and pitch changes to audio file on Android using Superpowered
body: <p>In a android project im working on, there is a option for the user to record a audio file and send it to another user.
  After the user records it, i want the option of adding an effect of "echo" or a pitch change, and send the new audio file created with one of those effects.</p>
  
  <p>I want to know if this is possible using <a href="http://superpowered.com/" rel="nofollow">Supowerpowered</a> and if so, i would like some example, sample or pointers on how to do so.</p>
  
  <p><strong>Edit</strong>: I also dont mind using an alternative library if there is any.</p>
