Editing Automatic double tracking (section)

==ADT versus manual double tracking==
Townsend's process succeeded in simulating manual double tracking quite effectively; however, attentive listeners can often tell the difference between ADT and "real" double tracking, with the former having a synthetic quality to it and having none of the audible differences between the vocal tracks frequently present in the latter. Over the years, many artists, including the Beatles, continued to use both manual double tracking, ADT, or a combination of both in different circumstances depending on the effects they wished to achieve, with each technique thought to have certain unique qualities of its own.
