Purveyors of Sonic Excellence Since 1993

Metropolis Mastering was founded in 1993 by Ian Cooper, Tony Cousins and Tim Young. Their motivation was simple: to create top quality audio to a standard never previously achieved. With the addition of more world-class engineers, Metropolis Mastering is still raising standards and levels of expectation internationally.

The five mastering suites were designed and built to the highest possible specification, offering the best environment for critical listening, equipped with some of the most sought after equipment around and some of the UK’s most well-respected engineers. Our sole aim is to make your music the best it can possibly be. Industry leaders PMC describe our mastering suites as, “the best audio environments in the world.”

Whatever your requirements, our audio engineers will create the optimum sound that works best for your latest project. 

All of our rooms have PMC Monitoring, Prism ADA converters and a range of analogue EQs and compressors from Sontec, Avalon, Summit, Manley, Maselec and Shadow Hills. Our digital equipment includes kit by Daniel Weiss, Waves, and TC Electronic. Three of our mastering rooms are purpose built for 5.1 surround sound and we have two customised Neumann VMS80 lathes for cutting vinyl.

Our multi-award winning mastering engineers at Metropolis work every day on full album projects, one-off tracks and remixes, vinyl cutting, 5.1 surround sound mixes, online music mastering, Blu-ray, archive catalogue remastering; whatever you need, we can deliver.

Our team of world renowned mastering engineers have extensive credits including Amy Winehouse, U2, Adele, Bjork, The Killers, Led Zeppelin, Madonna and The Beatles.


In addition to mastering for digital download and CD, we offer a broad range of further services to suit your every need.


Mastered for iTunes

Through research, knowledge and experimentation, the mastering engineers at Metropolis developed ways to optimise your music for iTunes so that it sounds fantastic when encoded to Apple’s AAC format, and as such we were one of their first UK-approved mastering facilities for the format.


5.1 Surround, DVD & Blu-ray

We have three bespoke 5.1 surround mastering studios, designed to offer the very best environment for critical listening. With the facility to sync audio to picture, we have everything you need to complete your project whether it’s for DVD, Blu-ray or Blu-ray Pure Audio. After years of research and development, we have created an unique stereo to 5.1 upmix algorithm, to create stunning 5.1 from a stereo source. This has proved very popular on projects that require surround sound but only have stereo masters, and can be heard on many successful releases.


Our online music mastering service, iMastering, is ideal if you don’t require an attended session. It’s a cost efficient and convenient way of getting your music mastered. All iMastering sessions are carried out by the same award-winning mastering engineers listed in the Engineers section, using the same kit, techniques, care and attention as any other session.

Vinyl Cutting

Our mastering engineers have decades of combined experience in cutting vinyl and know how to get the very best from the format. As the format enjoys a well deserved resurgence, our specialism in professionally produced vinyl results in stunning sound quality which comfortably holds its own against CD and other digital formats. We have two lovingly maintained Neuman VMS 80 cutting lathes, which have been further modified for optimum results.

Half Speed Vinyl Cutting

Vinyl cutting at half speed is a highly specialised process, and we are one of the few mastering studios in the world capable of this superior method of cutting. Both the playback system and the cutting lathe work at half speed, putting less stress on the vinyl cutter head. This produces a louder, cleaner cut which far surpasses what is achievable on a standard speed cut.

Live Direct-To-Vinyl

A live, direct-to-lacquer vinyl cut is a truly unique undertaking in this day and age. It is a highly labour-intensive and intricate all-analogue process, harking back to the days before tape recording was introduced midway through the last century. Synchronised, simultaneous live performing, engineering, mixing, mastering and cutting of the record eliminates all scope for hiding behind any modern production techniques, and is not for performers faint of heart!

The process is so intricate that it requires a team of specialists to execute, and Metropolis Studios is one of the very few places on the planet still doing it. Capturing an artist’s live performance direct to a vinyl master, completely bypassing any digital processing and any other recording processes, produces a truly unique and ‘real’ sound that is impossible to replicate.
