I recorded a video of a barbershop quartet performing in a house. Unfortunately, there is a noticeable background rumbling noise that I believe is from the air conditioning . As far as I know, Movie Maker 2012, which I believe is the current version, has no way to remove that background noise. So I want to use Movie Maker to save only the audio (I know how to do that), then remove the audio from the project file, then use Audacity to remove the background rumble from the audio, then use Movie Maker to import the audio file that Audacity created without the rumble. Is it possible to do that with Movie Maker 2012?
