The sound comes from the Law & Order franchise created by Dick Wolf, with Law & Order: Special Victims Unit premiering in 1999 as its first spin-off. Composer Mike Post created the famous two-note sting to mark scene changes and act breaks across the series. Over decades of episodes and reruns the Dun Dun became one of television's most recognised audio cues. Clips and parodies on social media later turned it into shorthand for any overly serious investigation, keeping it popular far beyond the show itself.
About this sound
The iconic two-note Dun Dun sound from Law & Order SVU, used to mark a dramatic reveal, a crime scene cut, or a sudden plot twist in edits and memes.
This is the short two-note sting known as the Dun Dun or Buh Buh from Law & Order: Special Victims Unit. It hits as two low, heavy, percussive chords with a slight metallic echo, separated by a brief pause. There is no voice or melody, just that instant drop into seriousness. Viewers hear it and immediately expect a body discovered, a suspect caught lying, or a case taking a darker turn. Online the effect is pure mock-drama, turning an ordinary moment into a crime scene investigation with a prosecution-worthy reveal.
