    1.26 + * 
    1.27 + * Demonstrates advanced use of the audio capture and recording features.
    1.28 + * Multiple perspectives of the same scene are simultaneously rendered to 
    1.29 + * different sound files.  
    1.30 + * 
    1.31 + * A key limitation of the way multiple listeners are implemented is that 
    1.32 + * only 3D positioning effects are realized for listeners other than the
    1.33 + * main LWJGL listener.  This means that audio effects such as environment
    1.34 + * settings will *not* be heard on any auxiliary listeners, though sound 
    1.35 + * attenuation will work correctly.  
    1.36 + * 
    1.37 + * Multiple listeners as realized here might be used to make AI entities 
    1.38 + * that can each hear the world from their own perspective.
