Andy Miles / Mastering Engineer

Andy Miles in the Super Audio Mastering studio

Andy’s interest in sound engineering developed from a young age, dubbing back and forth using a karaoke machine. Eventually moving on to completing on-location recordings for singers and songwriters. After deciding to pursue a career in audio engineering Andy embarked on a Sound & Music Production degree course, hosted by DBS Music in the South-West UK, where he flourished, employing his troubleshooting skills as a technician and working every session he could (training on their Neve 51 Series console) in their on-site commercial studio, which has been host to various clients, Joss Stone, Rick Nowels, Mad Dog McRea and Rik Mayall to name a few. He graduated his degree with Honors in Sept 2009 and it was in that same year that he met Simon Heyworth.

Andy joined SAM three months later, in December 2009, putting an end to Simon’s 2 year search for a potential protegé. After joining the team at SAM, Andy experienced the ultimate baptism of fire, being thrown into the middle of some very challenging Stereo and 5.1 projects, working with Simon and Robert Fripp on the King Crimson catalogue and assisting Simon on the Nick Cave & The Bad Seeds DVD-A series. Tackling both Stereo and 5.1 Mastering, although incredibly challenging, proved that Andy already had many of the skills necessary to facilitate the attention to detail which is so crucial to everything we do in Mastering.

Working with a highly skilled and seasoned Mastering engineer like Simon Heyworth has enabled Andy to ‘master’ Simon’s renowned ability for critical listening and perfectionist attitude. This is epitomised in Andy’s work with artists such as Robert Fripp, Imogen Heap, Simple Minds, Alison Moyet and labels like DGM/Panegyric, Universal, Mute, Sony and Beggars.

In addition to his experience in Mastering, due to his keen sense of balance in 5.1 surround sound, Andy is also developing a reputation as an exceptional 5.1 surround mix engineer, most notably mixing Goldfrapp’s ‘Tales Of Us’ (with Will Gregory), Recoil’s ‘A Strange Hour In Budapest’ (with Alan Wilder) and GRICE’s ‘Propeller’ (with GRICE) in 5.1 Surround at the Super Audio Mastering facility.

Andy says, “being a part of the family at SAM/MWorld enables us to deliver exceptional quality over a variety of formats and mediums at various levels of budget and needs. We always go the extra mile and will never conform to the bedroom studio and ’conveyor-belt’ type facilities that bash albums through without enough care or attention. We want our clients to experience Mastering the way it should be, with engineers who take the time to make their music the absolute best it can be. Our bespoke approach to each project facilitates that and is just one of the many reasons that our clients return to work with us again and again”.
