Adding Sound with MP3 Files

Sound can be added to the screens by adding a MP3 file with the same name as the screen being displayed e.g. name the file ready.mp3 to play a sound when the ready.jpg screen is displayed. The MP3 file will play for its full duration unless another MP3 file replaces it. If you want to cancel a long MP3 file when the next screen is displayed you can use a short silent file with the name of the next screen.
