 /**

  * 

  * 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.
