Applause has long been the standard way for a live audience to show approval, and short auditorium recordings became a staple sound effect as video editing moved online. Creators use this kind of clip when there is no real crowd in the footage, adding it to speeches, talent show edits, classroom presentations and staged reveals. Its popularity comes from how universal it is: a few seconds of clapping needs no explanation in any language and immediately signals success, gratitude or a job well done.
