Place this clip immediately after a repeated line in an edit, then follow it with a Dun Dun Dun for the reveal and a Bell Ding to mark the punchline landing. Keep the echo as the bridge between the repeat and the payoff, not the closing sound.

This is a short echo effect lasting about three seconds, with a single sound repeating and fading as it bounces back. It feels spacious and a little uncanny, like a call in an empty room coming back to you. That lingering repeat makes it easy to notice and hard to ignore.
