Editing Automatic double tracking (section)

===Doubling echo===
{{Main|Delay (audio effect)}}

A similar technique to ADT is [[doubling echo]], which uses short delays to mimic the double-tracking effect. Many effects units were developed to produce similar sounds, such as [[chorus effect|chorus]], [[flanger]]s, and [[phaser (effect)|phasers]], all of which use an oscillating delay (or, in the phaser, a variable phase network).  Other notable uses of ADT doubling echo are apparent on select material by [[Elton John]].  Some examples of this can be heard on Nigel Olsson's drums, especially the tom toms, on the songs "[[Don't Let The Sun Go Down On Me]]" from the ''Caribou'' album, as well as "Better Off Dead" and 
"[[Someone Saved My Life Tonight]]" on ''Captain Fantastic and the Brown Dirt Cowboy''.
