The audio begins with the echoing sound of footsteps approaching, resonating through a quiet space. The rhythmic patter grows gradually louder, indicating someone's steady progress towards a destination. Then, there's a brief pause, a moment of silence that's almost tangible, as if the listener is holding their breath in anticipation. Suddenly, the distinctive hum of automatic doors comes to life. It's a familiar, comforting sound, almost like a low sigh as the doors glide open smoothly on their own. There's a sense of ease and efficiency, a symbol of modern convenience that we often take for granted. The footsteps resume, now softer, as if muffled by the interior of a building. The doors hum back into silence, closing seamlessly behind the unseen visitor. The audio ends on this note, leaving behind a sense of satisfaction and a hint of intrigue about the journey that lies ahead.
