I am using Movie Maker video editor PRO. Video clips I shot at the beach have have a lot of wave sound. That's fine but when I edit the clip to play in slow motion, the sound also slows and becomes awful to listen to. I'd like to delete the original sound and then insert a sound track. Any ideas of how to delete the original sound? I tried Audacity unsuccessfully and don't want to sign up for VEED etc.Thanks,Lee
