Use audio in PowerPoint presentations, from background music to sound effects. Learn all about the PowerPoint audio feature here.
You can modify your audio files using the commands on the Playback tab. For example, if you add a song to a slide you can trim it to play only a brief section. You can also add a fade in and fade out, and add bookmarks that allow you to jump to specific points in the audio file.
There are other options you can set to control how your audio file will play. These are found in the Audio Options group on the Playback tab.
