10 hours of Pure Black Screen Audio Recording taken from inside a shelter while the rain lands on the metal roof. Thunder can be heard as well. Very High quality binaural recording.

And it's in 4K!

(some find it useful for a screensaver, insomnia, focus, relaxation, calming meditation or a way to prevent a computer from going to sleep, white noise for sleeping baby, check the screen for backlight bleeding, broken pixels on the monitor etc.)
