Best Program for Adding Audio

[Munchito696]

I was wondering if anybody knows of any free editing software that would allow me to add sounds to my video. I would prefer one where you can add multiple sound files and also keep the original audio from the video. Thanks!

Is SV free? I thought you had to pay for it.
