Place this clip on the cut itself, not under dialogue, and use it to close one beat before starting the next. Pair it with the Law and Order Dun Dun Sound Button when you want a mock-serious turn, placing the dun dun after it for the fake courtroom reveal.
About this sound
This clip is the short slap bass riff used as a scene transition, built from popping, muted funk bass notes over about four seconds. It feels playful, smug and instantly knowing, like a punchline just landed off camera. It comes from the sitcom Seinfeld, where the bass sting punctuated cuts between stand-up bits and apartment scenes.
