"When an American football team's offense is ready to run a play but decides at the last second to change what it's going to do, it calls an audible at the line of scrimmage. An audible is a verbal instruction that can slightly change the predetermined play, or completely scrap it for something else. A quarterback often calls an audible when he doesn't like how the offensive play that was called matches up with the defensive formation" (James Alder, 2018).
