I recorded audio for a PowerPoint presentation and now a colleague wants me to send the presentation to him. The file is currently 18 MB and I want to get it down to handy 1 or 2MB by stripping the audio.

The only way I see is to remove the audio in the animation bar slide by slide.

Stripping notes can be done by the "inspect document" feature. But for audio I see no such way.

How can I remove the audio all at once?

The solution is to go to the Slide Show menu » Record Slide Show » Clear Narrations.

Simply click on the sound icon on your slide and press SHIFT+DELETE... Do this for each slide

Beside the office button,under quick access toolbar,left click the undo option.You can undo whatever actions is done,including record narration.

That will only undo the last action, not remove the narration from all slides. – DavidPostill Jul 12 '15 at 14:01
