Car on gravel is a practical foley sound effect built around the distinctive crunch of tires on loose stone, a noise filmmakers have relied on for decades to sell an outdoor location without showing it. Credited to sound recordist Alan McKinney, this 15-second recording is used as stock audio rather than taken from a film or game. Editors share it on soundboards for quick access during video and podcast production, where it works as an instant cue for arrivals, departures and travel across unpaved ground.
