Great, but with a massive flaw

This is a very great app. The effects are very realistic and it is very simple to use. But just one problem. The audio. Whenever I add any audio effect, no matter how long or short, there is always a light saber "hummmmmmmmmm" as long as the audio is on. There is nowhere to turn it off, and it ruining my videos. PLEASE FIX SOON!
