Sounds and music are put on the Web in different formats and can be listened to in a number of ways. You can copy certain sounds from the Web to your computer through a method called downloading. (Once the sound file is downloaded to your computer, you can listen to it whenever you wish.) You can listen to some sounds right here on the Web. Downloaded sounds need small programs called "plug-ins" in order to play. For more information about which plug-ins you may need, please see Internet Tools.
