In the audio titled 'Pane of Glass,' a vivid scene unfolds at a school setting. The ambience of a bustling educational environment fills the air. Amidst the daily routines, an unexpected, resonant thump echoes, drawing attention. There's a sudden pause, then the distinct sound of a hard object hitting something. Soon, the source of the noise reveals itself; it's the sound of a pound against a glass window. The hit creates a sharp, crisp noise that reverberates around the school premises. The glass vibrates under the force but doesn't shatter, instead, it emits a clear, ringing sound that leaves an unsettling impression. The audio then fades, leaving behind the echoes of the thump against the pane of glass, a reminder of the mysterious incident at the heart of the school day.
