Abstract
A device and method for producing sound which simulates the sound of an engine, whereby sound segments are digitally stored in memory and accessed by a microcontroller which is responsive to a user accessible switch. When the switch is activated and the device is producing an acceleration or deceleration sound, the device will 'match' the acceleration or deceleration sound with a closely matched deceleration or acceleration sound, respectively, so that a realistic engine sound is produced.
