Chapter 29. Multimedia and PowerPoint > Inserting Sound Files

Inserting Sound Files

With slides of information, clip art, and pictures, PowerPoint presentations are effective by themselves. However they can be even more attention-grabbing with sound effects added to the presentation. These sound effects can come from many sources, including a prerecorded sound file, a music track from a CD, or a custom narration for your presentation. To use sound files effectively, you must have the proper hardware installed on your computer and the computer that will be used to give the presentation: a sound card, speakers, and a microphone to record narration. If you will be playing a music CD, your computer will also need a CD-ROM drive. Most new computers and many laptop computers have everything you need built-in, so they should be able to play sound effects.

PowerPoint recognizes different types of sound files. The more popular of these are WAV, which are more like real recordings of actual sounds, and MID, which are MIDI (musical instrument digital interface) music files. Depending on your computer's sound card, these files can sound like either an organ or a full-size orchestra.
