The fastest way to add music to PowerPoint

Open your presentation, click the slide where you want the music to start, then go to the Insert tab and select Audio. Choose Audio on My PC to pick a file from your computer, or Online Audio to search for a sound. The audio icon appears on that slide, and you can drag it to reposition it or resize it. When you run the slideshow, the music plays automatically when that slide appears — unless you change the settings to require a click first.

The music file must already exist on your computer or be accessible online. PowerPoint accepts MP3, WAV, M4A, and several other formats. If your file is in a different format, you can convert it using free tools like Audacity or an online converter before adding it to your presentation.

Key Takeaways

  • Insert audio through the Insert tab, then Audio, then Audio on My PC or Online Audio — the file must already be saved on your computer or available online.
  • The audio icon sits on the slide itself, and you can hide it during playback by checking the "Hide During Show" option in the Audio Tools tab.
  • By default, audio plays automatically when the slide appears; change this to "On Click" in the Playback settings if you want to start it manually.
  • Audio plays only on that one slide unless you trim it or adjust the timing; music that should continue across multiple slides needs to be added to each slide or handled through a different method.
  • Test your slideshow before presenting to confirm the audio file plays, the volume is audible, and the timing matches your speaking pace.

Adding audio from your computer

Click the slide where you want the music to begin. Go to Insert at the top of the ribbon, then click Audio and select Audio on My PC. A file browser opens. Navigate to the folder where your audio file is saved, select it, and click Insert. The audio icon appears in the center of the slide as a small speaker symbol.

You can now move the icon anywhere on the slide by clicking and dragging it. Many presenters move it to a corner or hide it entirely. To hide the icon during the slideshow while keeping the audio playing, click the audio icon, go to the Audio Tools tab that appears, and check Hide During Show. The icon vanishes when you run the presentation, but the sound still plays.

If your audio file is in a format PowerPoint does not recognize — such as OGG, FLAC, or WMA — you will need to convert it first. Audacity is a free program that can open most audio formats and export them as MP3 or WAV. Online converters like CloudConvert or Zamzar also work if you prefer not to install software.

Setting when the music plays

By default, audio starts automatically the moment the slide appears. If you want to control when it starts, click the audio icon, go to Audio Tools, and look for the Start dropdown under Playback. Change it from Automatically to On Click. Now the music only begins when you click during the presentation.

You can also set a delay. In the same Playback section, find Play Across Slides and check it if you want the audio to continue playing even when you move to the next slide. Without this checked, the music stops as soon as you advance. This is useful for background music that should span multiple slides, though the audio file itself must be long enough to cover all those slides.

To control volume, right-click the audio icon and select Edit Audio, or use the volume slider in the Playback tab. Test the volume in a quiet room before presenting, since projector speakers are often quieter than your computer's built-in speakers.

Trimming audio to fit your timing

If your audio file is longer than needed, you can trim it without editing the original file. Click the audio icon, go to Audio Tools, and click Trim Audio. A window opens showing the waveform of your sound. Drag the green handle at the start to where you want the audio to begin, and drag the red handle at the end to where you want it to stop. Click OK to apply the trim.

The trim only affects how PowerPoint plays the file — it does not change the original audio file on your computer. If you need to use the full version elsewhere, the original remains untouched. This is helpful when you have a long song but only want 30 seconds of it during a particular slide.

Adding the same music to multiple slides

If you want background music to play across several slides, you have two main options. The first is to add the audio to each slide individually and set Play Across Slides on each one. This works but requires repeating the process for every slide, and the audio will restart if you go backward in the presentation.

The second option is to add the audio to the first slide, set it to Play Across Slides, and make sure the audio file is long enough to cover all the slides you want it to play through. For example, if you have five slides and want 30 seconds of music on each, you need a 2.5-minute audio file. This approach is cleaner and avoids the audio restarting if someone clicks backward.

If neither option works for your needs — for instance, if you want different music on different slides — add each audio file to its own slide and leave Play Across Slides unchecked. The music will stop when you move to the next slide, and the new slide's audio will start.

Troubleshooting audio problems

If the audio does not play during your slideshow, first check that the file format is supported. PowerPoint accepts MP3, WAV, M4A, ALAC, FLAC, OGG, and WMA on most systems, though support varies slightly by version and operating system. If you are unsure, convert the file to MP3 using Audacity or an online tool.

If the audio plays on your computer but not when you present on a projector or different machine, the audio file may not have traveled with your presentation. PowerPoint does not automatically embed audio files into the presentation file itself. To fix this, go to File, click Info, and look for an option to Compress Media or Embed Media. This bundles the audio into the presentation so it plays anywhere. Note that this increases the file size and may take a few minutes to complete.

If the audio is too quiet or too loud, adjust the volume through the Playback tab or by right-clicking the audio icon. If it is still inaudible, test your computer's speaker volume and the projector's volume separately before your presentation.

Frequently Asked Questions

Can I add music that plays throughout my entire presentation?

Yes, but it requires planning. Add the audio to your first slide, check Play Across Slides, and ensure the audio file is long enough to cover every slide. If your presentation is 10 minutes long, the audio file must be at least 10 minutes. If the file is shorter, the music stops partway through.

What if I want different music on different slides?

Add each audio file to the slide where you want it to play. Leave Play Across Slides unchecked so each audio stops when you advance. The next slide's audio will start automatically if you set its start option to Automatically.

Will the audio file travel with my presentation if I email it or move it to another computer?

Not automatically. To ensure the audio plays on any computer, go to File > Info and select Compress Media or Embed Media. This bundles the audio into the presentation file itself, making it larger but portable.

Can I record my own voice or music directly into PowerPoint?

Yes. Go to Insert > Audio and select Record Audio. A recording window opens where you can speak or play music near your microphone. Click the red record button to start, then stop when finished. The recording is saved and added to that slide.

What audio formats does PowerPoint support?

PowerPoint accepts MP3, WAV, M4A, ALAC, FLAC, OGG, and WMA on most versions. If your file is in a different format like AIFF or AAC, convert it to MP3 using Audacity or an online converter before adding it to your presentation.
