Mixing and Mastering Engineer

Cassius WM on SoundBetter

London-based mixing and mastering engineer with professional studio experience, specialising in clean, balanced, artist-led mixes.

I’m a London-based mixing and mastering engineer working primarily in Logic Pro X, offering mixing, mastering, and vocal editing, including tuning and timing where needed.

My approach focuses on bringing out the strongest qualities in your recording, prioritising balance, clarity, and musicality rather than over-processing with effects and plugins.

I hold an MA in Music Production (BIMM) and have worked in professional studio environments, assisting on sessions under producers such as James Ford, with experience on projects involving artists including Bastille, The Script, and Black Country, New Road. This background has shaped a workflow that’s efficient, detail-oriented, and collaborative.

I work closely with artists throughout the process, encouraging clear communication and reference-based feedback to make sure the final mix reflects what you’re aiming for. Whether you’re finishing a single or preparing a release, I aim to make the mixing and mastering process straightforward and stress-free.

Feel free to get in touch if you’d like to discuss your project or hear examples of my work.
