Some might say that Townsend’s invention is the closest artificial double tracking has ever come to the real thing. Today we have so much that we can use to manipulate the sound to get an effect that’s in the ballpark to ADT, but it just doesn’t provide the same sound. He called the effect ADT or Artificial Double Tracking. That’s why Abbey Road chief engineer, technical director, and later studio manager Ken Townsend came up with an ingenious way of simulating a double track for The Beatles by using a couple of tape machines that’s still tough to duplicate even today (although Waves now has a nice simulation). Trying to match the timing and nuances of a vocal takes a lot of time and can be super frustrating for both the singer and the production team.

If you’ve ever tried to intentionally double track a vocal track you know that it can be a lot tougher than you think.
