Enormous Metal Sliding Door

The audio begins with the low, groaning sound of an enormous metal sliding door, echoing the weight and size of its iron structure. The audio recording was made in an open field, which amplifies the door's resonating noise, making it the focal point of the recording. Suddenly, the sound changes, signaling the door's progression from closing to opening. Its iron composition reverberates with each movement, creating an atmospheric echo that fills the field. This sound is repetitive and consistent, reflecting the door's function and movement. Each opening and closing cycle conveys a sense of strength and security, a testament to its formidable presence.
