I am working on a contract job that involves updating courses that were created in Presenter '09. I need to use audio from the existing courses, but the source files are unavailable. Is there a way that I can extract audio from the published files? I have seen on past, very old forum posts that the audio should be stored in the .ppta file, but I'm not clear on how to extract it from there. Any help on this is very appreciated! Thanks in advance!
