The audio begins with the soft whisper of tiny particles being released. A cascade of metallic powder is falling, creating a melodious symphony of minute clinks and clanks. Each particle is like a tiny bell, ringing as it tumbles down, bouncing off its brethren in a chaotic yet harmonious dance. The sound is much like rain, but with a more solid, metallic edge to it, a chorus of glittering droplets cascading down. This creates a mesmerizing soundscape, painting an aural picture of a waterfall of shimmering, metallic powder. The sound gradually fades, leaving behind a sense of awe and tranquility.
