Experiment with the loop and pitch fields of the AudioClip.
Exercise Two
Change the minBack, minFront, maxBack, maxFront parameters and see how
the sound changes when you navigate the space
Exercise Three
Add another sound in the scene and see how the sounds mix. Extend
the example to toggle between two sounds on clicking some object
using the Java control.

Place the sound inside an LOD or Switch node and see how it is
affected in the scene graph traversal. Try putting the sound
node inside a Transform and move the sound about with an object.
