Mastering is that necessary final stage, the polish that is required to make your recording ready for public release and consumption. The idea is not to change your recording, but to enhance it, allowing it to have maximum impact on the audience. Different kinds of music have different requirements – a dance tune will need to sound good on a big full-range soundsystem whereas a recording of a folk act is more likely to be heard on a hi-fi or headphones. When mastering I aim to be as sensitive as possible to the artists original intentions. I want to make your music as effective as possible at point of delivery, and stand up well next to the recordings of your contemporaries.

Over the past five years I’ve been doing mastering and mixdown work for many different labels and producers. I’m primarily focussed on electronic dance music but have worked with bands, solo performers, noise and drone artists and much more. The primary goal is for your music to sound competitive and to acheive its maximum potential.

“Sandy has golden ears. He is able to pick out and improve many small details that, when added up, significantly improve the clarity and transferability of the sound. He can also make it LOUD while preserving the dynamics of the given music. Will definitely be using his expertise again.”

“The Masters i get back always bring out the best in my mix-downs, whilst also being loud and clean. would recommend to any producer who wants to hear there tracks at a high quality for a good price”

“Sandy’s a real pleasure to work with, he added the polish I was looking for without crushing any of the dynamics in my mix. His ability to turn tracks around quickly and take note of requests made for an easier, higher quality release that I was really happy with.”

Tom / Oddfellow – Mostly Allsorts
Working with Sandy (well, not really working with him, that gives me too much credit) was an absolute joy. He’s an excellent Mastering Maestro / Good Bloke combo, so communicating with him was always fun. He made it clear that he would only be happy with the end result, when myself or those who created the tunes were happy. This took off a lot of stress as I’m a massive stress-head anyway….
Would recommend his services to anyone or everyone!”

Andy Gladwell – Bird Noire
“I contacted Sandy to master our tracks because I was always impressed at the high quality of his output – both individual and client work. Throughout the mastering process he was sensitive to our wishes and made absolutely sure that we were happy with the final masters. His friendly approach made the whole experience stress-free and resulted in some brilliant sounding masters of our songs! If you are seeking an independent mastering engineer cannot recommend his services enough.”
