/**
  * This sketch demonstrates how to use the <code>bufferSize</code> method of a <code>Recordable</code> class. 
  * The class used here is <code>AudioOutput</code>, but you can also get the buffer size of <code>AudioInput</code>, 
  * <code>AudioPlayer</code>, and <code>AudioSample</code> objects. The <code>bufferSize</code> method returns 
  * the length of the buffer it is using to receive or send samples. You can usually indicate the buffer size that 
  * you want when you get an audio class from <code>Minim</code>.
