Strange Noises coming from the Sky?

This video shows how easy it is to make your own or reproduce the noises in the sky phenomena. This took a few minutes to make, I ripped the audio from another video and then cross faded it with my video. While recording the video my dog started to bark which made it a bit more realistic. I don’t doubt the existence of these noises but until I hear them I can’t decide if it’s a viral marketing campaign, a copycat hoax or the real deal.
