Changing pitch

Dean Masters

I used to like Audacity to change the pitch of a karaoke track on my windows PC. Maybe in the past I have needed to lower the pitch rather than raise it. but I have one song I need to raise the pitch but Audacity just lowers it and makes it sound muddy. Is there any other free program where I can change the pitch of a song? I like audacity because it tells you what key you are in and what key you want to go to where other programs I have tried in the past just made changes by percentage, etc. which I have no idea how to run.
