Sound Across Slides in PowerPoint for the Web

Loop an audio clip to play across slides in PowerPoint for the Web. Using this option, you can span music or any other sound across multiple slides.

After inserting an audio file such as a music file within your PowerPoint presentation, do you want to play music that loops continuously in your presentation, without any interruption as you move from one slide to another? You must ensure that the music clip you are using is suitable for this purpose. A soft music clip that spans across your slides can make the flow between slides smooth, as long as the sound is not jarring or distracting for your audience.

Sound Across Slides: Pros and Cons

Yes, playing across slides in PowerPoint is a great feature but it has its caveats. If a presenter is going to speak along with the slides, then, it goes without saying that you should double check if you must add any music clip that spans across slides. Not only can a looping music audio make the audience inattentive, but the speaker will be at a distinct disadvantage too, trying to compete with the audio clip for the audience's attention.

Yet, if you are showing a bunch of successive slides that include pictures, and no speaker is accompanying the slides, then, adding a music clip to span across slides may be a good idea.

Save and Proceed

As far as possible, work with a presentation that has been saved at least once. Also, do explore our PowerPoint Friendly Audio Formats page to understand which common and exotic audio file types you can insert in PowerPoint.

Here's how you can add a music audio clip to play across slides in PowerPoint for the Web:

  1. Navigate to the slide where you want the audio clip to begin playing, which is usually the first slide of the presentation. Now, insert the sound clip in this slide, as explained in our Insert Audio (Sound) in PowerPoint for the Web tutorial. By default, PowerPoint for the Web will embed the sound clip within the presentation.
  2. Select the audio icon on the slide, as shown in Figure 1, below.

  3. Figure 1: Audio icon selected
  4. You will notice that selecting the audio icon makes the Playback contextual tab active on the Ribbon, as shown in Figure 2, below.

  6. Contextual Tabs

  7. The Playback and Format tabs are contextual tabs. Contextual tabs are special tabs in the Ribbon that are not visible all the time. They only make an appearance when you are working with a particular slide object which can be edited using special options.
  8. The Playback tab offers you different options to control the playback of the audio you have selected. Click the Start drop-down list, and choose the Automatically option, highlighted in red within Figure 3, below.

  10. Now, check the Play Across Slides and Loop Until Stopped options, highlighted in red within Figure 4, below.

  12. In PowerPoint for the Web, there is no support for Media animation events although they are supported for playback if added via the desktop versions of PowerPoint. We will therefore skip checking if PowerPoint has set the sound to stop playing after 999 slides.
  13. Why 999 Slides?

  14. You find 999 typed in the After text box since that's the largest number that PowerPoint will allow you to add.
  15. Rather than following steps 3 to 6, you can access the Playback contextual tab active on the Ribbon, as shown in Figure 5, below. Next, click the Play in Background button, highlighted in red within Figure 5. Doing so replicates all actions taken in steps 3 to 6. To undo these steps, you can click the adjacent No Style button, highlighted in blue within Figure 5. Doing so removes all these settings at one go.

  17. Whichever option you may have chosen, you will continue to see an audio icon on the slide where you inserted the sound file. If you don't like to see the icon on the slide, you can check the Hide During Show option, highlighted in green within Figure 5, above. Alternatively, you can just drag the audio icon to anywhere off the Slide Area to the workspace area, as shown highlighted in red within Figure 6, below, and your sound shall still play fine.

  19. Make sure you do so only if you choose the Automatically options in the Start drop-down list, shown in Figure 3, previously on this page. If you choose the When Clicked On option, the audio icon needs to be visible, to click upon!
  20. Save your presentation often.
