The audio starts with a distinct, percussive sound - a knock, sharp and clear. It's the sound of a fist hitting a wooden surface, resonating with a strong echo. The knock repeats, each impact clear and defined, like a rhythm being played out. Suddenly, there's a louder sound, a smack, like a collision that disrupts the rhythm. It's intense, like something heavy striking against the wood. Then, a bang follows, creating a loud and echoing effect. The sounds are all centered around the door, giving a sense of someone or something making contact with it. The audio ends leaving a lingering sense of anticipation.
