fixing audio on old slides to match audio quality on new slides?
I developed a training module for a client in 2012 and recently had to update it with new slides. The quality of the audio doesn't match at all. The older slides sound tinny and the newer slides are clear. I have changed laptops between module development, but not sure that would be the factor affecting the sound quality.
My question is, rather than re-recording all 68 slides, is there a way to reduce the tinny sound of the older slides. I think it is pretty clear from the audio file waves that a setting was different between the old slides and the new slides, but I'm not sure how to adjust them to match.
Any suggestions would be welcomed!
