How to Add Audio to Google Slides & PowerPoint: Complete Guide + Better Alternative

Adding audio to your presentations can transform a static slideshow into an engaging, multimedia experience. Whether you're using Google Slides or PowerPoint, voice narration helps your audience better understand and retain information.
In this guide, we'll show you exactly how to add audio to Google Slides and PowerPoint. We'll also introduce you to a faster, more efficient alternative - Denser AI Slides - that lets you add voice narration with just a few clicks.
Why Add Audio to Your Presentations?#
Before diving into the how-to, let's understand why adding audio matters:
- Increased engagement: Voice narration keeps viewers focused and interested
- Better accessibility: Audio helps visually impaired users consume your content
- Self-paced learning: Viewers can watch presentations on their own time with full context
- Professional polish: Narrated slides feel more complete and thoughtfully crafted
- Remote collaboration: Share presentations with coworkers who can understand them without you being present
How to Add Audio to Google Slides#
Google Slides doesn't have a built-in audio recording feature, but you can add audio files from Google Drive. Here's the step-by-step process:
Step 1: Prepare Your Audio File#
First, you need to create your audio narration separately:
- Use a recording app like Audacity, Voice Memos (Mac/iPhone), or any audio recorder
- Record your narration for each slide
- Save the file as MP3 or WAV format
- Make sure your audio quality is clear and professional
Step 2: Upload Audio to Google Drive#
- Open Google Drive
- Click the + New button
- Select File upload
- Choose your audio file and wait for it to upload
- Once uploaded, right-click the file and ensure sharing settings allow access
Step 3: Insert Audio into Your Slide#
- Open your Google Slides presentation
- Navigate to the slide where you want to add audio
- Click Insert in the menu bar
- Select Audio
- Choose your audio file from Google Drive
- Click Select to insert it

Step 4: Configure Audio Settings#
After inserting the audio, you'll see a speaker icon on your slide. Click on it to access format options:
- Click the audio icon on your slide
- Click Format options in the toolbar (or right-click and select it)
- In the Audio playback panel, configure:
- Start playing: On click or Automatically
- Volume: Adjust the playback volume
- Hide icon when presenting: Check this for a cleaner look
- Loop audio: Enable if you want continuous playback
Step 5: Repeat for Each Slide#
Unfortunately, you'll need to repeat this process for every slide that needs narration. This means:
- Recording separate audio files for each slide
- Uploading each file to Google Drive
- Inserting and configuring audio on each slide individually
This can be extremely time-consuming for longer presentations.
How to Add Audio to PowerPoint#
PowerPoint offers more built-in audio features than Google Slides, including direct recording. Here's how to add audio to PowerPoint:
Method 1: Record Audio Directly in PowerPoint#
PowerPoint lets you record narration without external software:
- Open your PowerPoint presentation
- Go to the Insert tab
- Click Audio > Record Audio
- Name your recording and click the red Record button
- Speak your narration, then click Stop
- Click OK to insert the audio

Method 2: Record Slide Show with Narration#
For narrating your entire presentation at once:
- Go to the Slide Show tab
- Click Record Slide Show
- Choose Record from Beginning or Record from Current Slide
- Use the recording controls to narrate as you advance through slides
- Click Stop when finished
- Your narration is automatically attached to each slide
Method 3: Insert Pre-recorded Audio File#
If you have existing audio files:
- Go to the Insert tab
- Click Audio > Audio on My PC
- Browse and select your audio file (MP3, WAV, WMA, M4A supported)
- Click Insert
- Configure playback options in the Playback tab
Configure PowerPoint Audio Settings#
After adding audio, select the audio icon and use the Playback tab to:
- Set audio to play automatically or on click
- Play across slides (for background music)
- Loop until stopped
- Hide the audio icon during presentation
- Trim audio clips
- Add fade in/out effects
Common Problems with Adding Audio to Presentations#
While both Google Slides and PowerPoint support audio, the process has several frustrations:
Google Slides Limitations#
- No built-in recording: You need separate software to create audio files
- Manual process for each slide: Each slide requires individual attention
- File management headaches: Audio files live in Google Drive separately
- Limited editing options: No trimming or timing adjustments within Slides
PowerPoint Limitations#
- Complex interface: Multiple menus and options can be confusing
- File size bloat: Embedded audio significantly increases file size
- Compatibility issues: Audio may not play on all devices or when shared
- Time-consuming: Recording quality narration for each slide takes hours
