'''
This sketch demonstrates how to use the loop
method of a Playable class. The class used
here is AudioPlayer, but you can also loop
an AudioSnippet. When you call loop() it will
make the Playable playback in an infinite loop.
If you want to make it stop looping you can
call play() and it will finish the current loop
and then stop. Press 'l' to start the player
looping.
