Editing Automatic double tracking (section)

==Use by the Beatles==
The Beatles were ecstatic over Townsend's technique and used it throughout their 1966 album ''[[Revolver (Beatles album)|Revolver]]'' and on many of their subsequent recordings. It has been incorrectly claimed<ref name="Lewisohn" />{{rp|72}} that the first use of ADT was on the first half of Lennon's vocal track on "[[Tomorrow Never Knows]]", but in actuality, this vocal track features manual double tracking. Most of the double-tracked vocals heard on the rest of the album were created using ADT, while the group also used the technique on a number of the instrumental parts to colour the sounds – there is factually more use of ADT on the mono version of the album than on the more widely known stereo version, with the lead guitar on "[[Taxman (song)|Taxman]]" and the backwards guitar on "[[I'm Only Sleeping]]" treated with the effect.

When used on a stereo mix, ADT could be used to create the impression of two different vocal parts on either side of the stereo picture. This technique was used on the stereo mixes of "I'm Only Sleeping", "[[Love You To]]", "[[And Your Bird Can Sing]]", and "[[Doctor Robert]]" (on "[[Here, There and Everywhere]]", the similar effect heard is actually two different vocals manually double-tracked and panned; on "[[Eleanor Rigby]]", the effect is obtained by a combination of manual double-tracking and ADT). This technique could also be applied to instrumental parts as well: on "Love You To", the same use of ADT was applied to the acoustic guitar track, giving the impression of multiple guitars panned left and right.
