How to Add Pre-Recorded Audio Across Slides in a PowerPoint Video
Question details
The user wants to insert an MP3 audio file into a presentation and ensure it plays continuously across all slides when exported as a video, rather than restarting when the slide advances.

- Product
- PowerPoint
- Device & OS
- not provided
- Scenario
- Adding a continuous background music track or pre-recorded narration to a presentation before exporting it as a video.
- Observed behavior
- By default, inserted audio is set to 'In Click Sequence' and stops or restarts when transitioning to the next slide.
Ensure your MP3 or audio file is saved in a local folder on your computer and that your slide transitions and timings are finalized before configuring the audio playback.
Configure Audio Playback Settings in PowerPoint
Use PowerPoint's built-in Playback tab to adjust the audio object so it starts automatically and plays continuously across all slides during the video export.
To prevent audio from cutting off when slides advance, you must modify the audio object's playback behavior. These settings will apply both when presenting in Slide Show mode and when exporting the final presentation to a video format.
Navigate to the first slide, or the specific slide where you want the audio to begin. Go to the Insert tab on the top ribbon, click on Audio, select 'Audio on My PC', and choose your MP3 file.
Click on the inserted audio speaker icon to select it. On the ribbon, a new 'Playback' tab will appear under Audio Tools. Click the Playback tab and check the box that says 'Play Across Slides'.
Still in the Playback tab, locate the 'Start' dropdown menu. Change the setting from 'In Click Sequence' to 'Automatically'. This ensures the audio begins without requiring a manual click during the video export.
To prevent the speaker icon from appearing in your final video, check the 'Hide During Show' box in the Playback tab. Alternatively, you can click and drag the icon off the visible slide canvas.
Once your audio is configured, click File in the top left corner, select Export, and choose 'Create a Video'. Select your desired resolution and click the 'Create Video' button to finalize the export.

Frequently Asked Questions
Why does my audio stop when I move to the next PowerPoint slide?
By default, any audio inserted into a PowerPoint slide is tied specifically to that slide and will stop playing when you advance. You must select the audio icon, go to the Playback tab, and check 'Play Across Slides' to make it continuous.
Can I hide the audio speaker icon during the presentation video?
Yes. Select the audio icon, navigate to the Playback tab under Audio Tools, and check the 'Hide During Show' box. You can also simply click and drag the speaker icon completely outside the white slide boundary.
What audio formats work best for PowerPoint video exports?
MP3 and WAV files are highly recommended for PowerPoint presentations. MP3 files are typically preferred because they offer excellent sound quality while keeping the final file size relatively small, which helps prevent export errors.
