The audio begins with an elongated, low-pitched whooshing sound, reminiscent of a swift gust of wind or a wave sweeping across a vast, open space. The sound effect has a smooth quality to it, as if it's seamlessly transitioning from one end of the spectrum to another. It carries the familiar characteristics of a swish, yet it's deep and substantially resonant, creating an illusion of something large moving quickly. The echoic nature of the sound effect contributes to an atmospheric, space-like ambiance. It's a sound that could easily serve as an effective transition or backdrop in audio-visual media, enhancing the overall dramatic effect. The audio concludes as slowly and as gradually as it began, leaving behind a lingering sense of movement and depth.
