About me

Pressure Mastering is a professional audio mastering studio based in the UK ran by myself, Matt. I not only offer full audio mastering, but also physical vinyl records cut on my highly modified, in house lathe, with no minimum order. Alongside the music, Pressure Mastering is an anarchist studio with a strict policy of stamping out homophobia, racism, anti-semitism, class inequality and all forms of oppression. I donate a portion of my profits to grass roots human, animal and environmental rights organisations. If this works for you, get in touch, and always feel free to ask any questions.

Music for social change. People not profit.

Audio Mastering

I offer all areas of audio mastering, whether for digital formats such as CD or streaming, or physical formats such as vinyl or cassette. Once an order is placed, turnaround is generally 48 hours for a first master, which you will receive, listen to thoroughly and send feedback and your thoughts. I give unlimited revisions, the mastering is finished once you are 100% happy.

There are many factors to consider when mastering to ensure an end result that best suits your needs, such as file formats, overall sound, timeframe of the project etc. When making contact for a quote, please include as many details as possible.

Below is my requirements from you, when submitting mixes ready for mastering.


Bit Depth

Mixes must be supplied at full bit depth resolution, ideally 32bit, or if not, 24bit with appropriate dithering


Make sure all files are WAV or AIFF, and have the same sample rate as the project


No brick-wall limiting


No mix bus processing unless completely necessary for the sound

Fade Outs

Let the endings fade, do not chop off the audio tale


Be careful when using stereo imaging plugins, make sure there are no phase issues within the mix
