I have some sound effects and music files that have been embedded into the cast members of Director. I'm not familiar with director and
can get to the cast member but I need help on how I can export the sound out. I tried Audio Xtra and copy and paste function but couldn't get it to work
You can't copy and paste with the AudioXtra, but rather write code that will export sound cast members. I know I've provided such code on one of these forums to do exactly that - try searching on 'Audio Xtra' or 'AudioXtra'
