David Bartley AMPS

I’ve built my business by delivering excellent audio on strict deadlines, at well below Central London studio rates. 

In more than 15 years as a freelance audio engineer, I’ve gained significant experience in Soho post-production houses and boutique agencies. My recent work includes some of the biggest theatrical and home entertainment marketing campaigns in the UK.  

For me, mixing is about more than simply balancing the levels of a film. My approach is to tackle each project holistically, crafting a sound that will resonate with the target audience. Where necessary I will add sound design, record foley or clean up dialogue to ensure the best possible result. 

I am also a sound designer for games and game trailers and was delighted to be nominated for the Spilprisen Best Audio Award 2023. Projects include releases from Logic Artists and Activision, although no game will ever be more special to me than Goldeneye, which I played on my N64 during every waking moment of 1997. 

Occasionally I work on passion projects such as live sound engineering for bands and festivals, and recording bands in the studio. I enjoy keeping my portfolio broad as I’m interested in all aspects of sound, and I find that I always learn something from each new project or genre that helps me develop my core work. 

My monthly newsletter is all about sharing what I’ve discovered, and you can sign up for it here. Or if you would like to discuss a forthcoming project, get in touch
