Abstract: The present invention relates to an electronic engine sound duplicator simulator used in combination with an internal combustion motor, a battery, and an alternator. The sound duplicator simulator includes a motor rpm sensor, a sound duplicator microprocessor, an amplifier, a sound trim adjuster and a switch. When the internal combustion engine is powered, the microprocessor converts the rpm signal into a frequency modulated electric signal which generates a sound simulating that of a high performance vehicle. The sound trim adjuster prevents the frequency modulated electrical signal from being transmitted to the speaker means when there is a predetermined low motor rpm. The stitch is mounted on the dashboard of a vehicle for turning the microprocessor and amplifier on and off.
