Double tracking or doubling is an audio recording technique in which a performer sings or plays along with their own prerecorded performance, usually to produce a stronger or bigger sound than can be obtained with a single voice or instrument. It is a form of ; the distinction comes from the doubling of a part, as opposed to recording a different part to go with the first. The effect can be further enhanced by panning one of the performances hard left and the other hard right in the stereo field.
Automation
Artificial or automatic double tracking, also known as ADT, was developed at Abbey Road Studios by engineers recording
The Beatles in the 1960s. It used variable speed
tape recorders connected in such a way as to mimic the effect created by double tracking. ADT produced a unique sound that could be imitated but not precisely duplicated by later
analog delay and
digital delay devices, which are capable of producing an effect called
doubling echo. The effect is used to give one singer a fuller sound.
Examples
Double tracking was pioneered by
Buddy Holly.
John Lennon particularly enjoyed using the technique for his vocals while in the Beatles. Lennon's post-Beatles albums frequently employed doubling echo on his vocals in place of the ADT. Some critics complained that the effect gave the impression that Lennon recorded all his vocals in a bathroom, but some performers, like
Black Francis and
Paul Simon, value the rich
echo chamber sound that it produces.
Paul McCartney also commonly used this technique for his vocals while in the Beatles. Another notable example of double tracking can be seen in the 1991 hit album
Nevermind, where producer
Butch Vig would often double the vocals of lead singer
Kurt Cobain and several electric guitars to create a "sound big enough" as Vig once put it in an interview.
