The audio recording titled "Closed Window" begins with the distinct sound of a window being slid open. The wind blows gently through the gap, carrying the subtle song of distant birds. There's a brief pause before the window starts to slide closed, the squeak of the window frame resonating through the otherwise silent room. The echo of the window closing reverberates, signifying the end of the interaction with the outside world. The audio recording ends with the soft click of the window lock, the room now sealed off from the outside, leaving behind a sense of solitude and tranquility.
