There are times when adding audio to a web page can greatly enhance the goal you are trying to achieve with your design. For these situations, Microsoft Expression Web has a built-in method that allows users to quickly and easily attach a sound file to a web page.
The following types of sound files are recognized by and can be added to a web page in Expression Web.
- Wave Files - .wav extensions
- Midi Sequencer Files - .mid extensions
- RealAudio Files - .ram extensions
- AIFF Sound Files - .aif, .aifc, and .aiff extensions
- AU Sound Files – .au and .snd extensions
If the sound file you want to use is in a different format, you may be able to convert it to one of these accepted types by using a free online file conversion program like Media-Convert. On the other hand, if you're looking for a special sound file, check out some of these sources for free audio downloads.
