شاهد مقطع فيديو مجاني Interactive Audio in Need For Speed Shift

The first two clips in the video show a player driving off from the starting line. In each clip before the player drives off, two sounds in particular can be heard. The first is the sound of the crowd and PA system from the nearby grandstand, the second a loop of the car's engine idling sound. It cannot be known at the time of the game's creation how long the player will take before driving off, so the engine idle sound must be able to play continuously by looping seamlessly until the player hits the acceleration control.
