title: Android WebRTC - Mix AudioTracks for Conference
body: <p>I'm trying to solve a problem with WebRTC Native Android. I've successfully adapted the AppRTCDemo from a 1-1 call to 1-N calls. Currently I have the following scenario:</p>
  
  <ul>
  <li>A (me) can talk to/listen to B</li>
  <li>A (me) can talk to/listen to C</li>
  <li>B and C can't talk to or listen to each other. </li>
  </ul>
  
  <p>To accomplish that I (A) have 2 PeerConnections respectively with B and C. I understand I need to mix some how the media streams or audio tracks, or in other words:</p>
  
  <ul>
  <li><p>Mix (A, B) -> send to C</p></li>
  <li><p>Mix (A, C) -> send to B</p></li>
  </ul>
  
  <p>Any pointers on how to accomplish that? Thank you</p>
