Andrew is a pioneer of digital restoration processes, using state-of-the-art technology like CEDAR, much of which he helped in the process of early development which he uses on film scores, classical, jazz, spoken word audio, and all genres of pop music.

He engineers recordings from as early as 1897, through 78 records, vinyl and LP’s, tapes, CD, DVD, Blu-ray, and Dolby Atmos masters, and has worked with some of the most illustrious artists and producers from around the world, including in the USA, Europe, Russia, Africa and Asia.

In the world of Hollywood blockbusting films, his mastering work includes the scores for The Lord Of The Rings and Harry Potter ‘Harry Potter and the Half-Blood Prince‘, scored by Nicholas Hooper (which was nominated for an American Grammy Award), V For Vendetta scored by Dario Marianelli (which was nominated for an International Film Music Critics Award) and the BAFTA-winning film Atonement, again scored by Dario Marianelli, which received the Academy Award for Best Original Music Score, a Golden Globe Award and a World Soundtrack Award.

Andrew transferred the first (and thought ‘lost’) studio demo acetate recording of The Beatles song ‘Love Me Do’, owned by Sir George Martin and restored by Andrew and released for the first time on The Beatles Anthology box set.

In the classical world, he has worked with a litany of modern and past artists, including the world-famous cellist Mstislav Rostropovich on the box set of The Russian Years, The Complete HMV recordings of Noel Coward on EMI, (which was American Grammy-nominated), a 69 CD boxset of the world’s most famous singer Maria Callas: The Complete Studio Recordings for Warner Classics and in producing The EMI Classics Centenary Edition 11 CD Box set, for which he was American Grammy-nominated.
