Place it at the exact cut where the threat is revealed, after a low alarm builds the moment, then follow it with the FNAF Jumpscare Scream for a second scare that keeps the viewer on edge.
About this sound
This is a sub-second monster yell built as a jumpscare sting, a sudden harsh scream that hits fast and cuts off before it can settle. It feels startling and tense, the kind of burst that makes a quiet room jump. It comes from the FNAF horror-game world, where that abrupt scream marks the moment an animatronic catches the player.
