I specialize in mixing and mastering alternative, ambient, rock, indie and cinematic genres. Every project gets full attention, whether you're a rising indie artist or a podcaster looking for clarity. Let’s make your sound yours – honest, dynamic, and powerful.
Hi, I'm Kozi — founder of Kozi Studio. I started as a live musician and performer, so I know how personal your music is.
I now work full-time as a freelance mix and mastering engineer, focused on giving each track clarity, depth, and emotional impact.
My specialty is mixing rock, ambient, indie, cinematic, and instrumental genres, but I'm always open to different vibes and textures.
I work entirely in the box, but with a precise and detailed workflow to deliver professional, transparent, and polished results.
Whether you're recording at home or in a studio — I’ll treat your project with the care it deserves.
