How to Add Audio to PowerPoint Slides
You can add sound clips to a slide to emphasize a point or add some background audio to set a mood. However, make sure you don't go overboard because audio can be distracting.
A sound icon appears on the slide and Audio Tools tabs appear on the ribbon where you can adjust the audio.
If you need a very specific sound that you can't find online or that isn’t already saved to your computer, you can record a sound yourself instead.
There are additional useful options on the Playback tab, such as setting the audio to fade in or out, trimming the audio down, or inserting a bookmark.
To remove audio, just select the sound icon and press the Delete key on your keyboard.
