Remove all audio
One click strips the tracks, their speaker icons, the timing that played them, and transition and click sounds.

Before
A deck full of old narration and sounds
Outdated voiceover on some slides, a chime on every transition, and a file several times bigger than it needs to be.
After
A clean, silent .pptx ready for new narration
Every slide’s audio gone, design and animations untouched, speaker notes kept for the next narration.
Clean deck, fresh voice
Removing old audio is usually step one. Step two is new narration: tell Noty in the Studio chat and it writes the script from your slides and notes, voices every slide and hands back a PowerPoint that plays itself.
What gets removed, and what stays
Only audio goes. The tool edits each slide’s own parts and leaves the rest of the deck as it was.
Audio files
Every embedded audio file on your slides is deleted from the package, whether it’s an MP3, WAV, M4A or recorded narration. That’s where the size drop comes from.
Speaker icons
The audio objects on each slide go with their icons, including ones placed off the slide or hidden during the show.
Playback timing
The animation steps that start, stop or loop the audio are cut out. Every other animation on the slide stays, in its order.
Transition and click sounds
Sounds set on slide transitions and on clicking a shape or link are removed. The transition effects themselves stay.
Auto-advance timings
On by default: slides that had audio lose their timer, since a narrated slide’s timer matches the old narration. Untick it to keep every timing.
What stays
Text, images, video, charts, themes, animations, transitions and speaker notes. Audio on a slide layout or master isn’t touched, and the tool tells you if any is left.
Removing audio, three ways
PowerPoint can delete audio, but one icon at a time, and hidden icons and transition sounds are easy to miss.

Clean the deck above for free. Then tell Noty what the new narration should sound like and get the deck back narrated.
Why decks end up with stale audio
Narration ages faster than slides. A number changes, a product is renamed, a slide is reordered, and the recorded voice now says something the slide doesn’t. Re-recording one slide rarely matches the rest in tone and level, so the whole narration ends up needing to go.
Decks also inherit audio. A template from another team comes with transition chimes; a deck built from an old webinar still carries its recording; a slide copied from a narrated deck brings its audio along, hidden off the edge of the slide.
The result is a file that plays things nobody expects and weighs far more than its slides. Recorded narration is often most of a deck’s size.
Stripping it all at once gives you a clean base. From there, new narration is a text job: Noty writes a script from the slides and speaker notes, you adjust the words, and every slide is voiced again in one go, in any voice or language, including your own cloned voice.
Now narrate it properly
Noty writes new narration from your slides and notes, voices every slide in a natural voice or yours, and hands back a PowerPoint that plays itself.

Frequently Asked Questions
How do I remove all audio from a PowerPoint at once?
Drop the .pptx into the tool above and press “Remove all audio”. Every track, narration and sound on the slides is removed in one pass and the clean deck downloads automatically.
Will my animations and speaker notes be kept?
Yes. Only the animation steps that play audio are removed; every other animation, the transitions and all speaker notes stay as they were.
Does it remove recorded narration?
Yes. Narration recorded in PowerPoint is embedded audio on each slide, so it’s removed along with its icon. Tick the timings option (on by default) to also clear the slide timers that recording set.
Will the file get smaller?
Yes, by roughly the size of the audio removed. The tool shows the size before and after, and lists how much audio the deck holds before you remove it.
Is there a file size limit?
There is no set limit. The file is processed in your browser, so very large decks depend on your device’s memory.
Can Notevibes narrate the deck again?
Yes. Tell Noty in the Notevibes Studio and it writes narration for every slide from the slide text or speaker notes, voices it in a natural AI voice or your own cloned voice, and hands back a narrated .pptx that auto-advances, plus the MP3.
