Export audio from Presenter to MP3?

There is not an export audio function in Presenter. This could be for many reasons, but it may also be just lack of demand (that Adobe has heard). The other problem is that Presenter doesn't use a single MP3 file, there is one (sometimes more than one) for each slide.

As to the Audition, or other audio editing programs, I do feel that is a solution. However, I have found that recording my audio in a dedicated audio program gives me better editing capabilities and better quality. It also provides me with the ability to easily combine or export the audio for the presentation into multiple formats, meeting different needs. I personally don't use Audition because it doesn't give me the ability to take a single audio file, place markers and then split the audio file by the markers. To be fair, it may do that, but I just haven't sorted out how to do it. But, any tool should work. If you have the Creative Cloud, then try Audition. If you don't, you can try Audacity, which is free. Or, you can pick something in between, I like the AVS suite of tools, which is $59 and isn't a limited time price like they indicate. There are many others out there, so find one that you like if this will fit your need.
