Use sound and narrated audio files to enhance your presentation. Play audio files across multiple slides, play music during specific slides, or play background music along with narration. After adding the sound files, change the volume level and hide the audio icons on the slide.

There may be times when you want a single audio file to play during an entire slide show or from a particular slide to the end of the show. For example, you can add a voiceover to PowerPoint that will narrate your slides for you.

To play music across multiple PowerPoint slides until the audio ends:

Navigate to the slide where the music, sound, or other audio file should play.
