Audience laughter has long been a staple of comedy television and live recordings, where a crowd reaction signals that a joke has landed. Online, short versions of that sound became a handy editing tool as creators began cutting reaction clips, memes and short videos for social platforms. Because the clip is only a few seconds long, it fits neatly into fast-paced edits without slowing the rhythm. Its lasting appeal comes from familiarity: listeners instantly recognise the shared, approving feeling of a room laughing together.
