About Super Audio Mastering

Simon Heyworth

Super Audio Mastering

Super Audio Mastering’s Simon Heyworth established his reputation in recording at Virgin’s Manor Studios, most notably as co-producer of Mike Oldfield’s Tubular Bells.


During his years as a recording engineer/producer, Simon showed an early interest in Mastering by always attending the vinyl of any records he worked on. Record engineering took him through many innovative ideas including mixing in Quadraphonic, the industry’s first foray into Surround Sound.


After some years working as a music producer for Film/TV soundtracks, which took him to studios all over Europe, he decided to go back to his roots working as a technician in the studio.


During the early 1990’s Simon joined ‘Chop Em Out’. Due to his extensive experience working with analogue tape, exceptional care, attention to detail and creative nature, Simon made the perfect engineer to take the Chop Em Out Mastering division forward. In his time there he built up a wide array of credits and relationships with labels and artists Re-Mastering legacy catalogue and Mastering new albums.


Simon became part of the SACD pioneering group of Mastering engineers working in DSD in both Stereo and 5.1 Surround Sound.


In the summer of 2002 Simon moved to Devon establishing his own revolutionary Mastering studio, Super Audio Mastering, in the picturesque/stunning Dartmoor National Park.


In championing High Resolution Audio in Stereo and 5.1 Surround Sound, he Mastered various High Resolution Audio projects for: Simple Minds, Nick Cave & The Bad Seeds and Depeche Mode. His Stereo work encompasses a wide array of genres and artists (Imogen Heap, King Crimson, Goldfrapp, Marillion, Dan Deacon, Brian Eno, George Harrison’s ‘The Dark Horse Years 1976-1992’ box-set, Charles Aznevour to name but a few (click here for more details).


Having spent the best part of his career working with both Analogue Tape and High Resolution Audio, Simon offers the highest quality Mastering in Stereo and 5.1 Surround Sound for CD, Online, DVD, Blu-ray & SACD.

Andy MilesAndy Miles


In August 2016 Andy is stepping away from SAM to spread his wings and further his career in Stereo Mastering. Strangely enough he has in fact only moved 30 mins down the road to StarDelta Mastering.


Since 1999 Simon has championed the use of Surround Sound and has been an early adopter for many techniques and formats that facilitate it. Since 2013, as well as Mastering, Andy and Simon have moved into the world of Mixing in 5.1 and with Andy’s keen sense of balance in 5.1 surround sound, he is developing a reputation as an exceptional 5.1 surround mix engineer.


His credits so far include…


Goldfrapp’s “Tales Of Us” (with Will Gregory)
Anthony Phillips’ “The Geese & The Ghost” (with Ant Phillips)
Anthony Phillips’ “Wise After The Event” (with Ant Phillips)
Anthony Phillips’ “Sides” (with Ant Phillips)
Anthony Phillips’ “1984” (with Ant Phillips)
Recoil’s ‘A Strange Hour In Budapest’ (with Alan Wilder)
GRICE’s ‘Propeller’ (with GRICE)


Having mixed all their records at the Super Audio Mastering facility, Simon and Andy have established themselves as a phenomenal team in the world of 5.1 Surround and have been producing mixes that (according to some reviewers) “truly rank among that particular art form’s crowning achievements.”


Andy says, “It is very sad to be stepping away but I will always feel like part of the family at SAM. I am thrilled to have been able to to deliver such exceptional quality over a variety of formats (Stereo and 5.1 Surround). I have always strived for our clients to experience immersive audio the way it should be, 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”.


Andy will return to SAM for any future 5.1 Surround projects so get in touch for a quote or to find out more!

The Studio

Located in the Dartmoor National Park in the South West of England, Super Audio Mastering is established as one of the world’s finest Mastering facilities. Housed in a spacious granite-walled roundhouse, the studio is fully equipped to Master your music, both in Stereo and Surround for CD, DVD, Blu-ray, Online Distribution or SACD.


Super Audio Mastering (SAM) does not compromise on quality and is not a ‘one-size-fits-all’ type service. Simon and Andy’s clients are testament to the fact that they work with their clients, not just for them. The whole experience is much more involving for the Artist. This is art meets technology, this is rock ‘n’ roll! And as such deserves the very best from seasoned professionals taking time, care and attention. This is exactly what SAM does.


Since opening the doors in 2002, SAM has been host to numerous new albums from new artists as well as seminal legacy productions in both Stereo and 5.1 Surround Sound. With on-site accommodation SAM offers the highest standard in Mastering coupled with the welcoming, relaxed environment of a family home and of course not forgetting the idyllic retreat and stunning vistas of Dartmoor.
