/**
  * This sketch demonstrates how to use the <code>getControls</code> method of a <code>Controller</code> object. 
  * The class used here is an <code>AudioOutput</code> but you can also get the controls of  
  * <code>AudioSample</code>, <code>AudioSnippet</code>, <code>AudioInput</code>, and <code>AudioPlayer</code> objects. 
  * <code>getControls</code> returns an array of JavaSound <code>Control</code> objects. You can determine what type 
  * of <code>Control</code> each one is by using the <code>getType</code> method and then comparing the type to one 
  * of the static control types of <code>Controller</code> (see the hasControl example). If you plan to use the 
  * <code>getControls</code> method you must also import the <code>Control</code> class from JavaSound (see the source).
