Yes but

That was a recording of radio waves converted to sound.
Did you watch the whole video? The main ones getting attention are shown on that video to be audio from the movie "War of the Worlds.

I have become a skeptic on almost everything that comes from the internet until I have solid proof that these are not Hoaxes committed by people or more importantly, government.
