• 1. be shure you have the QuickTime plugin version 6.5 installed.
• 2. be patient; your browser is loading 18 sound files now (1,3 MB).
• 3. if there are loading or playing problems, give your browser application more memory
  ... or use another browser (it works fine with Safari or Explorer on Mac).
  
  Now you can begin to play:
  Click on an arrow to play the sound. Each sound loops endlessly, you
  have to stop it. Control the volume of each sound by holding the speaker
  button. You may have best results using only two or three patterns together!
