This kind of success chime does not point to one widely recognized film, character, or meme source. It is most often used online as a generic reward or confirmation cue in short edits, game clips, app mockups, and reaction posts. The sound spread because people instantly understand its meaning without any setup: something worked. It is still popular for quick pacing, especially in videos that need a tiny positive beat similar to a correct answer sting or a polished interface notification.
