/**
*
* 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 circles

* 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.
