The referee whistle is one of the most recognisable sounds in sport, used by officials in football, basketball, rugby and other games to start play, stop play and signal fouls. Its sharp, high pitch was designed to carry across a noisy stadium, which is why it still cuts through video audio so well. Short whistle clips have become a staple on soundboards and in editing, where a single blast instantly sets a sports scene or adds a comic pause without needing any explanation.
