Need a little more information about who we are and what we do?
We are your favourite artists’ favourite mastering house. Each year, multiple projects we work on receive BRIT, Mercurys, MOBO and Grammy recognition.
Metropolis Mastering has been operating since 1993, consistently producing the highest quality of mastering sonics in the industry, whilst putting our stamp on some of the biggest hit records of each year – from the likes of George Michael, Amy Winehouse, Massive Attack and The Verve to Stormzy, Fontaines D.C., RAYE and Charli XCX.
Mastering Explained
The primary role of mastering is to present the mix to the world in the best possible light, whatever the final medium – whether it be tape, vinyl, CD, radio or streaming.
Mastering from A to Z
1644 WAV
The standard audio format, used by CDs, and accepted by all digital platforms.
2444 WAV
A higher bit-depth WAV, which is accepted by most platforms to allow for higher quality streaming.
WAV at Original Resolution
A 24-bit file at the same resolution as the provided mix (up to 96kHz). Supported by most digital platforms for their highest tiers.
Mastering from A to Z
MP3
A lossy file with a significantly smaller file size, ideal for fast sharing and good enough for casual listening.
ADM
Formerly known as Mastered for iTunes (MFiT), this is a 24bit WAV file optimised specifically to sound best on Apple Music. Often a good choice for other DSPs too.
DDP
A folder containing all of the audio and metadata that a CD manufacturer will use to create the final physical CD copies.
Mastering from A to Z
Vinyl
We offer two services as regards vinyl: cutting lacquers for sending to a pressing plant, as well as compiling continuous A / B side WAVs if you’ve already arranged your own cutting. Get in touch with our team for more details on these!
Dolby Atmos
An immersive listening experience enabled by technology that allows for a three-dimensional experience.
