title: Android: Mixing multiple AudioTrack instances?
body: <p>I need to run two instances of AudioTrack at the same time.  They must run separately because I'm playing them at different, variable sample rates.  I found that if I run them in the same thread, they "take turns".  I'm running them each in their own thread, but the audio is stuttering.</p>
  
  <p>Any ideas on making two instances play nice?  If not, any tips on mixing two short buffers into one, even if I want to play them at different sample rates.</p>
