Applause and crowd cheering have long been used in theatre, television, and live events to signal approval, and the same effect translates easily to short online clips. Creators reuse this kind of recording because it instantly tells viewers how to feel without needing any explanation or on-screen text. It appears in reaction videos, gaming highlights, comedy edits, and celebration montages, where a few seconds of clapping can turn an ordinary moment into a shared victory. Its simplicity is why it remains a staple sound effect for editors.
