Adding audio to your slides

To add a sound clip to PowerPoint, you insert the audio file directly into a slide using the Insert menu. Open the slide where you want the sound, click Insert at the top, then select Audio and choose Audio on My Computer. Navigate to your audio file (MP3, WAV, M4A, and other common formats work), select it, and click Insert. A speaker icon appears on your slide — you can resize it, move it, or hide it during playback.

The audio plays only when you click the speaker icon during your presentation, unless you change the settings. By default, PowerPoint does not auto-play sound when you reach that slide. This gives you control over when the audio starts, which matters if you are speaking over it or want to pause before playing it.

Key Takeaways

  • Audio files are inserted through Insert > Audio > Audio on My Computer, and the speaker icon can be moved or resized on your slide.
  • Sound plays only when you click the speaker icon unless you change it to auto-play in the audio tools that appear after insertion.
  • You can trim audio, adjust volume, and set it to play across multiple slides without restarting from the Audio Tools menu.
  • Embedded audio stays with your PowerPoint file, but very large files can slow down your presentation or make it harder to email.
  • If your audio file is not in a common format, convert it to MP3 or WAV before inserting it into PowerPoint.

Where to find and insert your audio file

Start by opening PowerPoint and navigating to the slide where you want the sound. Click the Insert tab at the top of the screen. In the ribbon, look for the Audio button — it usually appears in the Media section alongside Video. Click Audio and select Audio on My Computer from the dropdown.

A file browser window opens. Navigate to the folder where your audio file is saved, click the file name, and click Insert. PowerPoint embeds the audio into your presentation. A speaker icon appears on the slide at the size and position where you clicked. You can drag it to a new location, resize it by pulling the corners, or even make it very small if you want it less visible during your talk.

If you are inserting audio from an online source or a cloud service, click Audio and select Online Audio instead. You can paste a URL or search OneDrive for a file you have stored there. This method does not embed the file into PowerPoint — your presentation needs an internet connection to play the audio.

Controlling when the audio plays

By default, the audio plays only when you click the speaker icon during your presentation. This is useful if you want to introduce the sound before playing it or if you are speaking over it and need to start it at a specific moment. To test this, click the speaker icon on your slide and press the spacebar or click the play button that appears.

If you want the audio to start automatically when you reach that slide, right-click the speaker icon and select Play Settings. Check the box next to Start: On Click to change it. You can also select Start: With Previous to play the audio as soon as the slide appears, or Start: After Previous to play it after the previous animation or action finishes. This is helpful if you have multiple sounds on one slide and want them to play in a specific order.

You can also hide the speaker icon so your audience does not see it. Right-click the speaker icon, select Format Audio, go to the Picture tab, and check Hide During Show. The audio still plays when you trigger it, but the icon disappears during your presentation.

Trimming and adjusting your audio

After you insert audio, a Playback tab appears in the ribbon at the top. Click it to see your audio tools. The Trim Audio button lets you cut out the beginning or end of your clip without editing the original file. Click Trim Audio and a window opens showing your audio waveform. Drag the sliders at the start and end to mark where you want the clip to begin and finish, then click OK.

In the same Playback tab, you can adjust the volume using the Volume button. You can also set the audio to fade in or fade out by entering a time in the Fade In and Fade Out fields. If you want the audio to loop and repeat continuously, check the Loop Until Stopped box. This is useful for background music during a slide or for audio that should play multiple times.

If you want the same audio to play across several slides without restarting, right-click the speaker icon and select Play Settings. Check Play Across Slides. Now the audio continues playing as you move to the next slide instead of stopping when you advance.

File formats and file size concerns

PowerPoint accepts MP3, WAV, M4A, WMA, and AAC audio formats. If your audio file is in a different format — like OGG, FLAC, or an older format — you need to convert it first. Free online converters or audio software like Audacity can convert your file to MP3, which works reliably across all versions of PowerPoint.

Audio files embedded in PowerPoint increase the size of your presentation file. A short clip of a few seconds adds only a small amount, but multiple long audio tracks or high-quality recordings can make your file several megabytes larger. This matters if you need to email your presentation or share it over a slow connection. If file size is a problem, consider using online audio instead, or compress your audio files before inserting them.

When you share a PowerPoint file that contains embedded audio, the audio travels with it. Anyone who opens the file can play the audio without needing the original file. However, if you move or delete the original audio file from your computer after inserting it, PowerPoint still plays the embedded version — the link is broken, but the audio is safe inside the presentation.

Troubleshooting audio that will not play

If your audio does not play during a presentation, first check that you are clicking the speaker icon or that you have set it to auto-play. Click the speaker icon on the slide in edit mode and press the spacebar to test whether the audio works at all. If it plays in edit mode but not during your presentation, the issue is usually a playback setting.

If the audio does not play in either mode, the file may be corrupted or in an unsupported format. Try converting the file to MP3 using a free converter and inserting it again. If you are using online audio, check your internet connection — the presentation cannot play audio from a URL if you are offline.

Some versions of PowerPoint on older computers or on Mac may have trouble with certain audio formats. If you are presenting on a different computer than the one where you created the file, test the audio on that computer before your presentation. Bring a backup copy of your audio file on a USB drive in case you need to re-insert it.

Frequently Asked Questions

Can I add audio to a PowerPoint presentation on a Mac?

Yes. The steps are the same: Insert > Audio > Audio on My Computer. Mac PowerPoint supports the same audio formats as Windows PowerPoint. The Playback tab and all trimming and playback settings work identically on both systems.

What happens to the audio if I move the PowerPoint file to a different folder?

Embedded audio stays with the file and plays normally, no matter where you move the PowerPoint. If you used online audio instead, the presentation needs an internet connection to play it, and the audio plays from its original location online.

Can I record audio directly into PowerPoint instead of inserting a file?

Yes, but only in PowerPoint for Microsoft 365 (the subscription version). Click Insert > Audio > Record Audio, and PowerPoint opens a recorder. You can record up to 200 MB of audio per slide. The recording is embedded in the presentation just like an inserted file.

How do I make the speaker icon invisible but still let people click it to play the audio?

Right-click the speaker icon, select Format Audio, go to the Picture tab, and check Hide During Show. The icon disappears during your presentation, but you can still click where it was to play the audio. You may want to tell your audience where to click or use a note on the slide.

Will the audio play if I convert my PowerPoint to a PDF?

No. PDFs do not support embedded audio. If you need to share your presentation as a PDF and want to include audio, you will need to keep the PowerPoint file as well or use a different format that supports audio, like an HTML file or a video.
