I recorded a some audio files on my powerpoint presentation. This was done in two ways: (1) for some slides I used the record narration feature of powerpoint (the audio on each slide was recorded separately) and, (2) for others I used audacity to record the audio, which I imported into powerpoint.

I need to extract the audio file from each slide. I need to send just the audiofiles to someone. Is there a way I can extract the audiofiles?

Thanks
