It is very easy to add links to your web pages that let
your readers play sounds. Yep, the solution is the obvious
one that you've probably already figured out. If you wish,
you can use this exercise
to add some example links to sound files on your web page.
You can also add sound to your web pages by using more
advanced techniques such as java, javascript, and Flash.
For example, with javascript
it is possible to play sounds of your choosing when someone
enters or leaves your page, or when a person mouses over
certain parts of the page. Granted, these techniques are
more complicated than simply providing a link to a sound,
but they provide the possibility of more elaborate audio
effects.
