Extract audio from PowerPoint
Pull every embedded narration, music track and sound out of a .pptx as separate files, labelled by slide.
Need narration that isn’t there yet? Noty records it from your slides.
Three steps, done

Before
A .pptx with sound baked in
Narration recorded slide by slide, background music, sound effects — all sealed inside one PowerPoint file.
After
Separate audio files, per slide
MP3, WAV, M4A and the rest, exactly as they were embedded, named by slide and ready to reuse — one by one or as a zip.
Narration out of date? Let Noty redo it
Extracting is how you rescue the audio. Replacing it is how you move on. Tell Noty in the Studio chat and it writes the narration from your slides and notes, voices every slide, and hands back a PowerPoint that plays itself.
Where PowerPoint hides audio
A .pptx is a zip of XML files and media. Audio never lives on the slide itself — the slide points to a file stored elsewhere in the package.
The media folder
Every embedded sound is stored once in ppt/media, with a generic name like media3.m4a. That’s where this tool reads from.
Per-slide relationships
Each slide has a small relationships file that says which media it uses. That link is how each clip gets its slide number.
Narration from Record Slide Show
PowerPoint’s recorder saves your voice as one audio clip per slide. Each one comes out as its own file, labelled with its slide.
Background music
A track set to “Play across slides” is still a single file, linked to the slide where it starts. You get it once, not once per slide.
Transition and click sounds
Sounds attached to transitions or animations are embedded as short audio files too, so they show up in the list with their slide.
What isn’t included
The soundtrack of an embedded video stays inside the video, and audio linked from outside the file was never in the .pptx at all.
Getting the audio out — and replacing it
You can rename a .pptx to .zip and dig through ppt/media by hand. You get files called media7.m4a with no idea which slide they belong to.

Use the free extractor above to rescue what’s there. When the deck needs new narration, tell Noty — it voices every slide and hands back the .pptx and the MP3.
Re-using narration from an old deck
The most common reason to pull audio out of a PowerPoint is a deck that already has narration someone recorded years ago — a training module, a lecture, an onboarding walkthrough — and now it needs to live somewhere else: a podcast feed, an LMS, a video edit, or a new version of the slides.
Extracting gives you the original recordings, one per slide, in the format they were saved in. Nothing is converted, so the quality is exactly what was recorded. Drop them into an audio editor, stitch them together, or attach them to the new deck.
The catch with old narration is that it ages with the slides. Change a number on slide 7 and the recording is wrong. Re-recording means booking the same person, the same mic and the same room.
That’s where Noty comes in. Tell it to narrate the updated deck and it writes the script from your slides and speaker notes, voices every slide, and hands back a PowerPoint that auto-advances plus an MP3. If the original narrator was you, clone your voice once and the new narration still sounds like you.
Fresh narration in minutes
Noty narrates every slide in a natural voice — or yours — and hands back a PowerPoint that plays itself, plus the MP3.

Frequently Asked Questions
Which audio formats can it extract?
Any audio stored inside the .pptx with an MP3, WAV, M4A, AAC, WMA, OGG or FLAC extension. Each file downloads in its original format. Older WMA files may not play in the preview in every browser, but they still download.
Does extracting lower the quality?
No. The files are copied out byte for byte — no re-encoding, no compression. What you download is exactly what was embedded in the deck. The zip stores them uncompressed too.
Can I get narration I recorded with Record Slide Show?
Yes. PowerPoint saves recorded narration as one audio clip per slide (usually M4A, WAV in older versions), and each one is listed with its slide number. If you recorded with the camera on, that recording is a video, and videos aren’t extracted here. The tool reads the file on your device; nothing is uploaded.
Why does it say my deck has no audio?
There’s no audio file stored inside it. The sound might be inside an embedded video, linked from a file outside the deck, or the deck was saved as .ppt and converted without its media. If you want narration, Noty can write and voice it from your slides.
Is there a file size limit?
No fixed limit. Large decks with a lot of narration take a few seconds longer to read, and very large files depend on your device’s memory.
Can Notevibes re-narrate the deck instead?
Yes. Tell Noty in the Notevibes Studio and it voices every slide from its text or speaker notes, then hands back a narrated .pptx that auto-advances and an MP3 of the whole deck. Pick a natural AI voice or clone your own. Video export is coming with the next update.
