Add Listener by Damien Di Fede. This sketch demonstrates how to use the <code>addListener</code> method of a <code>Recordable</code> class. The class used here is <code>AudioPlayer</code>, but you can also add listeners to <code>AudioInput</code>, <code>AudioOutput</code>, and <code>AudioSample</code> objects. The class defined in waveform.pde implements the <code>AudioListener</code> interface and can therefore be added as a listener to <code>groove</code>.


  
  
  import ddf.minim.*;
  
  Minim minim;
  AudioPlayer groove;
  WaveformRenderer waveform;
  
  void setup()
  {
    size(512, 200, P3D);
    
    minim = new Minim(this);
    groove = minim.loadFile("groove.mp3", 512);
    groove.loop();
    waveform = new WaveformRenderer();
    groove.addListener(waveform);
  }
  
  void draw()
  {
    background(0);
    // see waveform.pde for an explanation of how this works
    waveform.draw();
  }
  
  void stop()
  {
    // always close Minim audio classes when you are done with them
    groove.close();
    // always stop Minim before exiting.
    minim.stop();
    super.stop();
  }
