Geoffrey Emerick (born 1946 in London) is a recording studio audio engineer, who is best known for his work with The Beatles' albums Revolver, Sgt. Pepper's Lonely Hearts Club Band, and Abbey Road.

Early career at EMI

Emerick first started working at EMI at the age of 15, as an assistant to engineer Norman Smith. As an unpaid trainee, Emerick witnessed the first-ever EMI recording session by the finalised lineup of The Beatles in 1962, during which the group recorded for the first time with new drummer Ringo Starr on what would eventually become their first hit single Love Me Do. As assistant engineer, Emerick worked on numerous early recordings by the Beatles, and also helped record other artists for the label, including Judy Garland. He assisted at the EMI artist test of The Hollies.Emerick, Geoff and Massey, Howard (2006). Here, There, and Everywhere: My Life Recording the Music of The Beatles. New York, NY: Penguin Group (USA) Inc.. pp. 387. ISBN 1-592-40179-1.

After working his way up to the position, Emerick engineered the 1966 number one UK Manfred Mann hit Pretty Flamingo."CNN.com - The teenager who shaped the Beatles - Apr 7, 2006". CNN Emerick took over the Beatles engineering duties from Smith that same spring at the request of producer George Martin when Smith became a producer. The first album Emerick worked on with the Beatles as their main recording engineer under Martin was Revolver, and "Tomorrow Never Knows" was the first track he worked on.

It was Emerick's innovation to record John Lennon's vocal through a Leslie speaker on that song, to get the ethereal sound Lennon wanted. He received Grammy Awards for the engineering of Sgt. Pepper's Lonely Hearts Club Band and Abbey Road. He abandoned work on The Beatles on 16 July 1968, fed up with the tensions and arguments that hampered the sessions.

After the Beatles

His post-Beatles career included work with Paul McCartney (including Band On The Run, which netted Emerick another Grammy, London Town, and Flaming Pie), Elvis Costello (for whom he produced Imperial Bedroom and All This Useless Beauty), Badfinger, Art Garfunkel, America, Supertramp, Cheap Trick, Nazareth, Split Enz, Mahavishnu Orchestra, Ultravox, Matthew Fisher's first solo album "Journey's End," and Jeff Beck, as well as Nellie McKay's critically acclaimed 2004 debut CD Get Away from Me. He was the sound engineer on Robin Trower's album Bridge of Sighs, and credited by both Trower and producer Matthew Fisher for that album's acclaimed sound.

In 2003, he received his fourth Grammy, this time for lifetime Technical Achievement.

In 2006, Emerick released his memoir, Here, There, and Everywhere: My Life Recording the Music of The Beatles (Gotham Books, ISBN 1-59240-179-1), co-authored by veteran music journalist Howard Massey.

On 3 April 2007 it was announced that Emerick would be in charge of a re-recording of Sgt. Pepper's Lonely Hearts Club Band by contemporary artists, including Oasis, The Killers, Travis and Razorlight. Emerick used the original equipment to record the new versions of the songs, and the results were broadcast on BBC Radio 2 on 2 June, marking the album's 40th anniversary.
