Trembling Doorbell Sound

As the audio begins, a trembling doorbell sound rings out, its pitch oscillating in an almost shaky manner. The sound is jarring, almost as if it's struggling to maintain a steady tone, creating a sense of anticipation and unease. Following the bell's ring, there's a distinctive noise of a door being opened; it creaks with a certain heaviness, echoing across the room. The sounds of the door opening and closing intermingle with the trembling doorbell sound, creating a rhythm that's both unsettling and captivating. The door seems to be closing with a slight force, causing a low thud that resonates for a moment before fading away. The audio ends with the doorbell ringing a final time, still trembling, leaving a lasting impression of unease and tension.
