Q: How to export audio from a narrated Power Point presentation? I want to update my slides but keep the audio.

A:  the question puzzled me for a second but I found a quick solution here. It worked for me.

If your audio is embedded in a PowerPoint file, you can extract the audio files by doing the following:

1. Save the presentation as a .pptx.
2. Navigate to the file in Windows Explorer, right click it and select rename.
3. Add “.zip” to the end of the file name so it looks like this: “filename.pptx.zip”.
4. Click enter.
5. Now, double click the file, then double click the ppt folder, then double click the media folder. You should see a list of all the media files in your PowerPoint.
