Unfasten ancient creaky entrance

As the audio begins, a deep sense of tension fills the air. The silence is punctuated by the disturbing sound of an ancient, creaky door. The door, made of old, weathered wood, groans under the weight of its years. The noise it emits is a high-pitched squeak that echoes in the stillness, adding to the suspense. Gradually, the sound evolves, indicating the door is slowly being opened. The creaking continues, each squeak filled with tales of the past, until finally, the sound fades away, leaving the listener with an eerie sense of having just unfastened a portal to a bygone era.
