NAMM 2014: Artificial Double Tracking Like The Beatles
Waves Audio has debuted Waves: Abbey Road Reel ADT, which they describe as the first plugin to successfully emulate Abbey Road Studios' pioneering process of Artificial Double Tracking. Here's the full details in Waves' own words...
ADT was the signature effect created at Abbey Road in the 1960s to meet the requirements of some very special clients: The Beatles. It is the most legendary of all Abbey Road tape effects and can be heard on countless historic recordings. Over the years, many recording engineers have tried to replicate the effect, but only with partial success. This is largely because a definitive description of the exact process used at Abbey Road has, until now, been a closely guarded secret. ADT was invented to meet the Beatles' unique recording needs. As the band's success grew, so did their desire to find new ways of working, leading Abbey Road's engineers to experiment with new technology.
