The fastest way to add music depends on where your audio file lives

To add music to a PowerPoint slideshow, insert the audio file directly into your presentation using the Insert menu, then set it to play automatically or on click. The process takes about two minutes and works the same way in PowerPoint for Windows, Mac, and the web version. You can add sound to a single slide, have it play across multiple slides, or loop it throughout your entire presentation.

PowerPoint accepts MP3, WAV, M4A, and AAC files. If your music is in a different format, you will need to convert it first using a free tool like Audacity or an online converter. The file size matters: very large audio files can slow down your presentation file, so keep music clips under 10 MB when possible.

Key Takeaways

  • Insert audio by going to Insert > Audio > Audio on This Device, then select your MP3 or WAV file from your computer.
  • Set the audio to play automatically when the slide appears, or require a click to start it, using the Playback tab that appears after insertion.
  • To make music play across multiple slides instead of stopping at the next slide, select the audio and check "Play Across Slides" in the Playback tab.
  • Test your slideshow in presentation mode before sharing it, because some audio formats or playback settings behave differently when you present versus when you edit.

Inserting audio on Windows PowerPoint

Open your presentation and click on the slide where you want the music to start. Go to the Insert tab at the top, then click Audio. Select Audio on This Device to browse your computer for the file. Navigate to the folder where your music lives, select the MP3 or WAV file, and click Insert.

A small speaker icon will appear on your slide. You can drag it to a corner or hide it behind a shape if you do not want it visible during the presentation. Click on the speaker icon to select it, then look for the Playback tab that appears in the ribbon at the top. This is where you control when and how the audio plays.

Inserting audio on Mac PowerPoint

The process is nearly identical on Mac. Click the slide where you want music, then go to Insert > Audio > Audio on This Device. Browse to your file, select it, and click Insert. The speaker icon appears on your slide the same way it does on Windows.

Select the speaker icon and the Playback tab will appear. Mac PowerPoint has the same playback options as Windows, so the rest of the setup is the same. If you are using PowerPoint Online in a web browser on Mac, the Insert menu works the same way, though some playback features may be limited depending on your browser.

Setting the audio to play automatically or on click

After you insert the audio, click on the speaker icon to select it. The Playback tab will appear in the ribbon. Look for the "Start" dropdown menu — this controls when the audio begins. Choose "Automatically" if you want the music to start the moment the slide appears. Choose "On Click" if you want to click during your presentation to start the music.

Most presentations use "On Click" because it gives you control over timing. If you are using music as background ambiance for a title slide, "Automatically" works better. You can also set the volume using the Volume button in the Playback tab, and choose whether the audio should loop (repeat) when it finishes.

Making music play across multiple slides

By default, audio stops playing when you move to the next slide. To make music continue across several slides, select the speaker icon, go to the Playback tab, and check the box labeled "Play Across Slides." Now the audio will keep playing even when you advance to the next slide, and it will only stop when it finishes or when you manually stop it.

This is useful for background music during a section of your presentation. If you want the music to loop and play continuously, check the "Loop Until Stopped" option in the same tab. Be careful with looping — it can become distracting if the audio clip is short and repeats obviously.

Converting audio files to a format PowerPoint accepts

If your music is in a format like FLAC, OGG, or WMA, PowerPoint will not recognize it. You need to convert it to MP3 or WAV first. Audacity is a free, open-source audio editor that runs on Windows, Mac, and Linux. read it, open your audio file, go to File > Export > Export as MP3, and save the converted file to your computer.

If you prefer not to install software, online converters like CloudConvert or Zamzar let you upload an audio file and read it in a different format. Upload your file, select MP3 as the output format, and read the result. The conversion usually takes less than a minute. Keep the converted file in a folder you can find easily when you insert it into PowerPoint.

Troubleshooting audio that does not play during presentation

If your audio works in edit mode but not when you present, the most common cause is that the file path is broken. This happens when you move your presentation file to a different folder or send it to someone else without including the audio file. PowerPoint embeds small audio files automatically, but very large files may only link to the original location.

To avoid this, keep your audio file in the same folder as your presentation, or use the File > Info > Check for Issues > Check Compatibility option to see if PowerPoint detects any problems. If you are sharing the presentation with someone else, send both the PowerPoint file and the audio file together, or use File > Save As and choose "PowerPoint Show" format, which can embed smaller files more reliably.

Frequently Asked Questions

Can I add music to just the background of one slide without a speaker icon showing?

Yes. After inserting the audio, right-click the speaker icon and select "Hide During Show." The audio will still play, but the icon will not be visible to your audience. You can also drag the speaker icon to the very edge of the slide or place it behind a shape so it is out of the way.

What is the maximum file size for audio in PowerPoint?

PowerPoint can handle audio files up to about 100 MB, but files larger than 10 MB can make your presentation slow to open and share. If your audio file is very large, trim it to just the section you need using Audacity or another audio editor before inserting it.

Will the audio play if I email my PowerPoint file to someone else?

Only if the audio file is embedded in the presentation. Small files embed automatically, but larger files may only link to your computer. To be safe, send both the PowerPoint file and the audio file together in the same folder, or ask the recipient to place them in the same folder on their computer before opening the presentation.

Can I fade music in or out during a slide?

PowerPoint does not have built-in fade controls. If you need fade effects, edit the audio file in Audacity before inserting it — add a fade-in at the beginning and fade-out at the end, then export it as MP3. This way the fade is part of the audio itself and will play the same way on any computer.

What happens to audio if I convert my PowerPoint to a video?

Audio plays normally when you export your presentation as a video file. Go to File > Export and choose the video format. PowerPoint will render your slides as video and include all audio, animations, and timing. The video file will be large, so this process may take several minutes depending on your presentation length.
