Place it at the exact moment a hidden place is revealed, after a short suspense cue and before the reaction shot. Put Dun Dun Dun just before it, then follow it with Vine Boom when the full scene lands, keeping the reveal as the centre of the edit.
このサウンドについて
Agartha is an 11-second sound built around its mysterious underground-city name, presented as a single short clip for the button. It carries a hidden, otherworldly mood that suits moments of discovery, secrecy, or a reveal from below. The name alone sets the tone, giving the short piece a sense of depth and quiet intrigue without needing any extra explanation.
