The audio begins with the distinct sound of a heavy metal door being unlatched, initiating a suspenseful silence. Suddenly, the colossal weight of the massive metal door is set in motion, the resistance against its rusted hinges producing an eerie creaking. The sound echoes through the air, reminiscent of a groaning beast being awakened from a long slumber. The metal-on-metal friction reverberates, an uncanny resemblance to the scraping of a metal dumpster dragged across concrete. The creaking intensifies, climaxing as the door swings wide open. The echo fades gradually, leaving behind an echoing silence that amplifies the enormity of the door's movement. The audio ends, leaving a lasting impact of an impending heavy presence beyond the now open door.
