As a mixing and mastering engineer and music release strategist, music producers often ask me, "how do I stand out from all the competition?" and my answer is simple, "there's very little competition at the top".

Ryan has been an absolute pleasure to work with. He’s brought my songs to another level. I was previously working with another company for mixing and mastering for my album but was not happy with the result. After a phone call with Ryan I decided to work with him instead and the improvement is marked he has helped bring my tracks to life and his professionalism is amazing , he’s always ready to discuss ideas and anything to do with music . I would give more than 5 stars if I could!

Been working with Ryan at Refine for over 10 years. He has always offered me a world class service with my mixing and mastering. Often going far beyond what's required and very often up against some very demanding deadlines. He's an absolute perfectionist and its ultimately exactly what you need when handling those very crucial steps in your audio. Highly recommend and thus its five stars from me.

I am Ryan Sullivan and my music experience includes working with some of the biggest artists, labels, and brands in the world. Some are hugely famous and some are just beginning their rise to the top and I love to be a part of that journey. I recently spent 7 years as head sound engineer for Red Bull Studios and have worked on major projects in various world-class studios.

Professional mixing and mastering are my technical specialties and I am passionate about levelling-up your music career, moving you up to the next level through powerful production, release strategies and marketing methods. I am fortunate and grateful to have seen many projects through to success.

I trained under legendary sound engineers Chris Palmer and Jasper Williams in the late 1990s and early 2000s and have since held high positions and consulted at various world-class studio facilities, brands, and record labels in various parts of the world. My work as a sound engineer, music producer, touring artist, label manager and music marketing consultant has had me lecture and consult for various agencies on sound engineering, audio technology, acoustics and marketing strategies for brands such as Ableton, Akai, Roland, Capitec Bank, CTEMF, JOOX, Modular Night ClubPioneer DJ, Red Bull, SAE Institute, Technics DJ Mix Club, Universal Music, V-Moda and more.

All of that work revolves around the artist and working with artists is my pleasure. I am grateful to work with people who inspire me, working together to make your music releases world-class.
