 /**

  * 

  * Demonstrates advanced use of the audio capture and recording

  * features.  Multiple perspectives of the same scene are

  * simultaneously rendered to different sound files.

  * 

  * A key limitation of the way multiple listeners are implemented is

  * that only 3D positioning effects are realized for listeners other

  * than the main LWJGL listener.  This means that audio effects such

  * as environment settings will *not* be heard on any auxiliary

  * listeners, though sound attenuation will work correctly.

  * 

  * Multiple listeners as realized here might be used to make AI

  * entities that can each hear the world from their own perspective.

 	 * You will see three grey cubes, a blue sphere, and a path which

 	 * monotone sound as it moves along the track.  Each cube is

 	 * listening for sound; when a cube hears sound whose intensity is

 	 * greater than a certain threshold, it changes its color from

 	 * grey to green.

 	 * 

 	 *  Each cube is also saving whatever it hears to a file.  The

 	 *  scene from the perspective of the viewer is also saved to a

 	 *  video file.  When you listen to each of the sound files

 	 *  alongside the video, the sound will get louder when the sphere

 	 *  approaches the cube that generated that sound file.  This

 	 *  shows that each listener is hearing the world from its own

 	 *  perspective.
