title: Real-Time Audio Loop Switching for iPhone
body: <p>I'm trying to find the best way to play a seamless loop of audio, that the user can switch out for another at the shortest possible notice, with a decent number (30-150) of very short loops being available.  Will OpenAL be sufficient for this, or do I need to delve into Audio Units?  The Apple Documentation says that for real-time feedback like an instrument, Audio Units is the right choice.</p>
  
  <p>I just want to get the community's opinion on this, and any links and sample projects would be greatly appreciated.</p>
