#pragma mark Example for reading out Pocketsphinx and Flite audio levels without locking the UI by using an NSTimer
// What follows are not OpenEars methods, just an approach for level reading
// that I've included with this sample app. My example implementation does make use of two OpenEars
// methods: the pocketsphinxInputLevel method of OEPocketsphinxController and the fliteOutputLevel
// method of OEFliteController.
//
// The example is meant to show one way that you can read those levels continuously without locking the UI,
// by using an NSTimer, but the OpenEars level-reading methods
// themselves do not include multithreading code since I believe that you will want to design your own
// code approaches for level display that are tightly-integrated with your interaction design and the
// graphics API you choose.
//
// Please note that if you use my sample approach, you should pay attention to the way that the timer is always stopped in
// dealloc. This should prevent you from having any difficulties with deallocating a class due to a running NSTimer process.
