SoundManager 2
While looking for a method to associate sounds with links on a webpage
for someone who wanted to have visitors to her website hear sounds of
pages turning when they clicked on left and right arrows on the
webpages, I came across
SoundManager 2, which uses JavaScript and Flash to provide a method
for playing sounds when someone clicks on an image, moves a mouse over it
etc. The software was developed by Scott Schiller and is free.
