Place this clip at the very start of a spooky scene, before any reveal, then follow it with the Drama Button Sound Effect as the camera moves closer, and close the moment with the Mission Failed Meme Sound if the scare falls flat.
About this sound
This is a very short voice clip, lasting under three seconds, of a single word, hello, spoken slowly in a cold, hollow tone that sounds wrong for a greeting. It feels unsettling and tense, like someone is standing just out of sight, and that quiet menace makes an ordinary word feel suspicious, awkward and hard to ignore.
