The sound comes from the demo version of Five Shift at Springtrap's, a fan-made horror game built around the animatronic Springtrap from the Five Nights at Freddy's universe. Like many fan-game scares, it was lifted from gameplay and shared on soundboards, where short, punchy jumpscares are easy to reuse in edits. Its brevity is part of its appeal: at under a second, it can be dropped into a video without breaking the pace. Fans of the series keep using it because it instantly signals a Springtrap encounter, even outside the original game.
