It enables you to control sound in a cross-browser/platform environment, using a language you already know.

A sample SoundManager code would be:

soundManager.createSound('myNewSound','/path/to/some.mp3');
soundManager.play('myNewSound');
soundManager.setVolume('myNewSound',50);

You see that it is really easy. This JavaScript Flash Sound API has other powerful controls like:

• stream
• autoplay
• onid3 – for ID3 tag displaying
• whileplaying
• and more..

Using SoundManager, you can easily create sound based web applications or more interactive background sounds for non-Flash websites.
