docs: You will see three grey cubes, a blue sphere, and a path which
  circles each cube.  The blue sphere is generating a constant
  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.
