rlm@14:  * 
rlm@14:  * Demonstrates advanced use of the audio capture and recording features.
rlm@14:  * Multiple perspectives of the same scene are simultaneously rendered to 
rlm@14:  * different sound files.  
rlm@14:  * 
rlm@14:  * A key limitation of the way multiple listeners are implemented is that 
rlm@14:  * only 3D positioning effects are realized for listeners other than the
rlm@14:  * main LWJGL listener.  This means that audio effects such as environment
rlm@14:  * settings will *not* be heard on any auxiliary listeners, though sound 
rlm@14:  * attenuation will work correctly.  
rlm@14:  * 
rlm@14:  * Multiple listeners as realized here might be used to make AI entities 
rlm@14:  * that can each hear the world from their own perspective.
