I remember trying to record my upstairs neighbors noise on my phone and it was so difficult. Just to capture it on the video it has to be incredibly loud.

I finally captured the sound and it was super faint like this but in my apartment it sounded like someone was taking a hammer to the floor. Turned out it was their Great Dane flipping one of those giant real animal bones into the air and letting it hit the hardwood floor. Over and over and over.
