The audio begins with a clear, distinct sound of fingers gently tapping on a glass pane. It's a rhythmic, almost musical pattern - a series of soft, sharp knocks that resonate, creating a soothing yet haunting echo. The sound reverberates, reminding one of a window being knocked on, perhaps by a visitor or a stray breeze. The tapping continues, steady and persistent, carrying a tone of anticipation. As the audio progresses, the tapping becomes more pronounced, creating a captivating melody of knocks against the window. The audio ends leaving an echo of the tapping, painting a vivid picture of a quiet room with a single glass pane bearing the brunt of these rhythmic taps.
