Place this clip at the reveal point of the edit, after a door knocking sound sets up someone arriving, then follow it immediately with a dun dun dun sound to close the scene on the consequence.
About this sound
This is a 5.5-second recording of a woman laughing in a high, theatrical way that builds rather than fading out naturally. It feels eerie and unsettling, the kind of laugh that makes a normal moment sound secretly villainous and a little too pleased with itself.
