Applause has been a staple reaction sound for as long as people have shared short clips online, because it needs no explanation. Creators use it to signal approval, success or a job well done, whether the moment is sincere, ironic or played for comedy. It works in gaming highlights, talent show parodies, award-style edits and reaction videos, often alongside kids cheering clips and other crowd reactions. Because the sound is instantly recognisable and emotionally clear, it continues to appear in memes and short-form videos whenever a creator wants the audience to join in the celebration.
