Squeaky automated library entrance

The audio begins with the subdued hum of an automated system, a sound that adds an eerie undertone to the atmosphere. This is followed by the unsettling squeak of a large, heavy door slowly swinging open, its creaking noise echoing throughout an expansive space, suggestive of a grand library. The door's groan is reminiscent of a spine-chilling scene in a horror movie, creating a sense of unease and anticipation. As the creaky noise eventually subsides, the door securely locks into place with a final thud, completing the unnerving symphony of this automatic library entrance.
