Hand clapping has been used for centuries to show approval, keep rhythm and signal the end of a performance, and recorded applause became a staple of radio, television and live albums. Online, short clapping clips spread through video editing, presentations and meme culture as a quick way to add approval without filming a real audience. Creators use this longer applause version when a moment needs more than a single clap, letting the sound build, sustain and fade like a genuine reaction from a small crowd watching together.
