'''Automatic double-tracking''' or '''artificial double-tracking''' ('''ADT''') is an [[analogue recording]] technique designed to enhance the sound of voices or instruments during the mixing process. It uses [[Delay (audio effect)|tape delay]] to create a delayed copy of an audio signal which is then played back at slightly varying speed controlled by an oscillator and combined with the original. The effect is intended to simulate the sound of the natural doubling of voices or instruments achieved by [[double tracking]]. The technique was developed in 1966 by [[Recording engineer|engineers]] at [[Abbey Road Studios]] in London<ref name=Martin>Martin, George, ''[[All You Need Is Ears]]'', St. Martin's Press, 1979, p. 155, {{ISBN|0-312-02044-9}}.</ref> at the request of [[the Beatles]].
