30-Second Swoosh Sound

As the audio begins, an abstract noise takes center stage, setting the tone for a dark and ominous atmosphere. It's a 30-second swoosh sound, reminiscent of a hit in a sci-fi setting. Immediately, you're transported into an otherworldly realm, and the auditory sensation morphs continuously, flowing like a metallic wave. The sound builds up, creating anticipation akin to the opening of an unseen door. It's a perfect transition sound, seamlessly bridging two elements. As the swoosh sound fades, it leaves a lingering presence that echoes in the dark, giving off an eerie yet engaging vibe.
