In this audio, the main feature is the sound of a door squeaking as it's slowly being opened. The screeching noise of the door's hinge creates a distinct atmosphere, reminiscent of domestic settings, perhaps an old, wooden house. Alongside the squeaking, there's the subtle sound of a lock being turned and the door shutting after being opened. The audio effect is created meticulously using foley techniques, making it feel exceptionally real and close. Recorded with a handheld device, the audio has a 'zoomed in' quality that adds to its immersive nature.
