Welcome to the official homepage of


I am an audio engineer based in Copenhagen, Denmark, working with recording,

mix, mastering and basically all other audio related projects.

When I am not in the studio I work freelance with live audio engineering.

Audio engineering is science and arts combined. Certain things are mandatory

for a process to be successful, however it is also very important for me

to include any ideas you might have for how you want your product to turn out.

Again, welcome. I hope you'll like it here.


A few examples of some of the projects I have worked on


When you are in the studio with Sebastian, you can clearly see how a career as a musician in the worlds of pop and rock music, has shaped him to become the producer he is today. Besides the fact that he has a very good understanding of what it is a song needs to take it to the next level, you are also in good hands technically speaking. Very recommendable collaborator, who I can definitely vouch for.

Sebastian is a very talented guy with a very keen ear for mix and mastering. In addition to that he is always very punctual, professional and pleasant to work with, which is important since you often find yourself under a certain amount of pressure in the final stages of a project.

Jesper Braae Madsen - Youth in Blue

Sebastian Vinther has mastered our debut EP Taking Over, giving the EP a homogenous, dynamic and versatile sound. Our music is both powerful and energetic but also fragile and airy. This can hamper the task of making a record glue together in mastering. Still, Sebastian has managed to achieve this with great conviction. Mamaré would like to give Sebastian our heartfelt recommendation.

Mathias Findalen Bickersteth - Mamaré

Sebastian is a responsive and thorough mastering technician who knows his craft, but also has a great understanding of meeting a specific artist’s aesthetic preferences. It has been a pleasure working with him and I look forward to the next collaboration.
