I am in charge of making music for my dance team and I really need help finding a good website to edit and add animations to music. The website has to be free, I don't mind downloading just as long as it doesn't cause viruses. Also,were can you find voices saying certain things like " you ain't ready for this" or something of that nature to add to my music. Please help as much as possible, I would really appreciate it.!

PS. I already know of Audacity.

Thanks for your time!
