Applause is one of the oldest and most recognisable audience reactions, used in theatres, studios, and broadcast recordings long before soundboards existed. As short audio clips became easy to share online, a clean applause recording became a staple for creators who wanted an instant, universal signal of approval without filming a real crowd. It works across languages and cultures because the sound needs no translation, and it remains popular for endings, victories, and celebrations where a visual alone might fall flat.
