Well for my radio production class we had to produce a 30 sec clip promoting adult continuing education using a pre-recorded clip of an interview with some lady named Sherry. So with some contributions from a friend the script was wrote. I then recorded the guys and added the background music, made by me, and with a little fiddling there you go. Took around an hour and a half to do the whole thing from script writing to finish.
Please contact me if you would like to use this in a project. We can discuss the details.
