I don't know why NASA TV lets those horrible hums at 1.33KHz and 2.66KHz out into the world, but I just filtered them out on my Mac using iZotope and Audio Hijack. 😬
@jsnell No no, I try never to be right on the internet! Or at least I don't want to be the well aktually dude. Lacking any experience with izotope I just wondered if there was some particular advantage.
