This sound comes from Call of Duty: Black Ops III, released in 2015, where it plays as a progression cue when a player ranks up. Outside the game, creators reused it in gaming montages, meme edits and streamer clips because the audio instantly communicates leveling up without any explanation. It remains popular because the BO3 interface sound is brief, sharp and widely recognized by multiplayer fans. You will also hear it in broader achievement-style edits alongside familiar game notification sounds.
