Adding a background sound
Internet Explorer supports the ability to play an audio file—”in the background”, so to speak—when a document is opened. The supported audio file types are: WAVE (.wav), MIDI (.mid), AIFF (.aif, .aifc, .aiff), and AU (.au, .snd). You can specify how many times the sound should repeat, or that it should repeat endlessly.
To add a background sound to a document
- On the Document menu, go to Property, click Document, and then click the Styles tab.
- Under Background sound, enter the path or URL to an audio file in the Path box. Click Browse to browse for a file on your local file system.
- In the Repeat box, enter the number of times the sound should play, or select Repeat forever.
- If you want to listen to the sound file you specified, click
. To stop playing the sound, click

- Click OK.
Background sounds are only supported by Internet Explorer.
