Sounds can add an extra dimension to your site. For example, if your company has an audio jingle, you can add it to the home page of your site and configure it to play when a site visitor browses to it.
With Microsoft Expression Web, you can embed an audio file and set properties to play when site visitors open the page. You can set the properties to play the sound file continuously, or to play it a specified number of times. Another way to add sound to your web page is to provide a hyperlink to the audio file from your page and let site visitors decide if they want to play the sound. When site visitors click that link, an appropriate audio player opens and plays the sound file.
If you include sound in your page, consider giving people an easy way to turn the sound off (for example, with a "No sound" or "mute" icon button).
You can add many types of audio file to your web page, including the following:
MPEG, Audio-Layer 3 files (*.mp3).
Wave files (*.wav).
Midi sequencer files (*.mid).
RealAudio files (*.ram, *.ra).
AIFF sound files (*.aif, *.aifc, *.aiff).
AU sound files (*.au, *.snd).
Microsoft Active Streaming files (*.asf).
