If you don't have power point, or if you want to be able to browse the embedded audio more easily, you can use this method:
- Rename
presentation.pptx
->presentation.zip
- Audio files in
.m4a
format inpresentation.zip/ppt/media/
I recommend VLC Media Player with [
and ]
keys to change speed among other shortcuts.
I hope you find this usefully improves your listening experience!
Edit: Some people are having trouble changing the file extension because it is hidden. You may need to check File extension names
under the View
tab in file explorer (Windows) or follow this tutorial (OSX).
