I have an audio recording of people whispering that would llikely be audible were it not for the white noise on the recording. I have heard that people can do remarkable things with sound editing programs. What are some programs that might be able to help me hear the words being said on this recording? What are some good programs (free if possible) for cleaning up white noise? Also, if anyone is really handy, would they be willing to do this project for me? Thanks in advance!
