Abstract ! This paper will cover the subject of Artificial Double Tracking, from the idea conceived by Ken Townsend in his car on the way home one evening, to its use in the development of new music and sounds that would greatly influence many musicians and engineers at the time, including The Beatles who used it extensively. ! Also covered will be the extremely unique equipment used in this process that could only be found at Abbey Road Studios at the time due to the extensive amount of modification EMI engineers performed on their equipment. ! Finally it will look in detail at the number of secondary effects that Artificial Double Tracking would create in its wake such as flanging, modulation and chorus, and how the traditional Artificial Double Tracking set up was modified slightly to achieve them.
