The sound comes from Microsoft Windows, where a short error chime has long been used as a system alert when an action cannot be completed or a program encounters a problem. Because almost everyone who has used a PC recognises it instantly, it moved naturally from desktop notifications into online video, memes and streams as a shorthand for failure. This version is trimmed to start immediately, which makes it especially useful for editors who need the cue to hit exactly on a mistake rather than after a pause.
