The audio begins with the sharp, quick sound of a zipper being swiftly pulled upward. The whoosh of it is almost like a swooshing breeze, cutting through the silence with rapidity. The fast, fluid motion of the zip is heard distinctly, a familiar sound that instantly brings to mind images of a zipper being closed with a quick, decisive tug. As the zipper closes, there's a brief, satisfying catch as the two halves join together, signifying an end to the swift, whooshing journey.
