The audio begins with the distinct sound of footsteps approaching on a concrete surface. A faint jangling of keys is heard, followed by the metallic clink of a lock being undone. The audio then captures the grating noise of a heavy metal lid being lifted. The hinges creak under the weight, echoing the distinct sound of metal on metal. Then, the lid is fully opened, and it bangs against the back of the bin, resonating a hollow metallic echo. The opening of the garbage bin is underscored by the ambient city noise in the background.
