The three ways to add audio to a PowerPoint slide

You can add audio to PowerPoint in three ways: insert a sound file you already have on your computer, record audio directly into the presentation, or embed audio from an online source. The method you choose depends on whether you have the file ready, whether you need to record something new, or whether you want to pull from a library.

All three methods work on both Windows and Mac versions of PowerPoint, though the exact menu locations shift slightly between them. The audio plays only during the slideshow — not while you are editing — and you can set it to play automatically when the slide appears or only when you click the speaker icon.

Key Takeaways

  • Insert audio from your computer by going to Insert > Audio > Audio on My Computer, then select the file and choose whether it plays automatically or on click.
  • Record audio directly into PowerPoint through Insert > Audio > Record Audio, which creates a new file stored inside your presentation.
  • Audio files larger than 100 MB may cause PowerPoint to slow down or fail to save, so compress large files before inserting them.
  • The speaker icon appears on the slide during editing so you can test the audio, but it disappears during the actual slideshow unless you set it to play on click.

Inserting an audio file from your computer

Open the slide where you want the audio to play. Go to the Insert tab at the top of the ribbon. Click Audio, then select Audio on My Computer. A file browser window opens. Navigate to the folder where your audio file lives, select it, and click Insert.

A speaker icon now appears on your slide. Right-click it and select Play Settings to choose whether the audio starts automatically when the slide appears or only when someone clicks the icon during the presentation. If you want the audio to play automatically, check the box next to Play Across Slides if the audio should continue playing even if the presenter moves to the next slide.

PowerPoint accepts MP3, WAV, M4A, and OGG files. If your audio is in a different format, you will need to convert it first using free tools like Audacity or an online converter. Test the audio before presenting by clicking the speaker icon while in edit mode — you will hear it play through your computer speakers.

Recording audio directly into your presentation

If you need to record something new, you can do it without leaving PowerPoint. Go to the Insert tab, click Audio, then select Record Audio. A small recording window opens with a red record button, a stop button, and a play button.

Click the red button to start recording. Speak into your computer's microphone. When you are done, click the stop button. You can play back what you recorded using the play button to check the quality. If you want to re-record, close this window without saving and start over. If you are satisfied, type a name for the audio file in the text box at the bottom and click Insert.

The recorded audio is now embedded inside your PowerPoint file itself, so you do not need to keep a separate audio file on your computer. However, this increases the file size of your presentation. If your presentation is already large, recording audio directly may make it difficult to email or upload.

Using audio from an online source

PowerPoint also lets you search for audio from online libraries. Go to Insert > Audio > Online Audio. A search box appears where you can look for royalty-free music or sound effects. The results come from Microsoft's own library and from Creative Commons sources.

Click on an audio file to preview it, then click Insert to add it to your slide. The audio is downloaded and embedded in your presentation, so it will play even if you open the file on a computer without internet. This method works best for background music or ambient sound rather than voice recordings, since the library is limited and search results can be unpredictable.

Controlling how and when audio plays

By default, the speaker icon stays visible on your slide during the presentation, and the audio plays only when someone clicks it. If you want the audio to start automatically the moment the slide appears, right-click the speaker icon, select Play Settings, and check Automatically. You can also hide the speaker icon by right-clicking it, selecting Format Audio, and adjusting the size to make it very small or moving it off the visible slide area.

If your audio is longer than a few seconds and you want it to play while the presenter is talking, use Play Settings to set it to start automatically and check Play Across Slides so it continues even if the presenter moves forward. This is useful for background music during a section of your presentation.

Test your audio settings before presenting by running the slideshow. Press F5 to start from the beginning or Shift+F5 to start from the current slide. Listen to make sure the audio plays at the right moment and at a volume that works for your room.

File size and performance issues

Audio files add to the overall size of your PowerPoint presentation. A typical MP3 file is 1 to 2 MB per minute of audio, so a 10-minute presentation with background music could add 20 MB or more. PowerPoint can handle presentations up to several hundred megabytes, but very large files may slow down editing, take a long time to save, or fail to open on older computers.

If your presentation is already large or you are having trouble saving it, compress your audio files before inserting them. MP3 format is smaller than WAV, and lowering the bitrate (quality) reduces file size further. Free tools like Audacity let you export audio as MP3 at different quality levels. A bitrate of 128 kbps is fine for voice or background music and takes up half the space of 256 kbps.

If you are sharing your presentation with others via email, check the file size first. Most email services reject attachments larger than 25 MB. If your presentation is too large, either compress the audio further, remove it and ask people to watch the presentation in person, or upload the file to a cloud service like OneDrive or Google Drive and send a link instead.

Troubleshooting audio problems

If the audio does not play during the slideshow, first check that your computer's speakers or headphones are turned on and the volume is not muted. Then open the presentation in edit mode, right-click the speaker icon, and click Play to test it. If it plays in edit mode but not during the slideshow, the audio file may be corrupted or in a format PowerPoint does not recognize.

If the audio file was on a network drive or external drive when you inserted it, and you later moved or deleted that file, PowerPoint will not find it during the slideshow. To fix this, re-insert the audio file from its new location, or move the file back to where it was when you first inserted it. If you recorded audio directly into PowerPoint and it disappeared, the file may not have saved properly — try recording it again.

On Mac, if audio plays in edit mode but not during the slideshow, check that you are running PowerPoint version 16.16 or later. Older versions of PowerPoint for Mac have known audio issues. Update your Office installation through the Mac App Store or by running the Microsoft AutoUpdate tool.

Frequently Asked Questions

Can I add audio to a PowerPoint presentation I am sharing online?

Yes, but the audio must be embedded in the file, not linked to an external file. If you inserted audio from your computer or recorded it directly, it is embedded and will play for anyone who opens the file. If you linked to a file on a network drive, that link will break when you share the file with someone else. Always use Insert > Audio > Audio on My Computer or Record Audio, not a hyperlink to an audio file.

What if I want the audio to play on multiple slides?

Insert the audio on the first slide where you want it to play. Right-click the speaker icon, select Play Settings, and check Play Across Slides. The audio will continue playing as you move through subsequent slides until it finishes or until you click the speaker icon again to stop it. This is useful for background music during a section of your presentation.

Can I edit the audio after I insert it into PowerPoint?

PowerPoint does not have built-in audio editing tools. If you need to trim, cut, or adjust the audio, edit it in a separate program like Audacity before inserting it into PowerPoint. If you recorded audio directly into PowerPoint and want to re-record it, delete the speaker icon and record again.

Does audio work in PowerPoint Online or on mobile?

Audio works in PowerPoint Online (the web version) if the file is embedded in the presentation. However, some audio formats may not play depending on your browser. On mobile devices, audio plays in PowerPoint for iPad and Android, but the speaker icon may appear in a different location or size than on desktop. Test your presentation on the device you will use to present before your actual presentation.

How do I remove audio from a slide?

Click the speaker icon on the slide and press Delete. The audio is removed from the slide but remains in your computer's file system if you inserted it from there. If you recorded audio directly into PowerPoint, deleting the icon removes the audio from the presentation entirely.
