Multi Awarded Online Mastering Studio for rock & metal.

In our Online Mastering Studio your sound is our first priority. This is our philosophy which we kept in mind for over a decade working for countless artists, companies, major- and indie labels. Working closely, hand in hand with our clients, we create masters defined by crystal clear sound and overwhelming dynamics without losing track of the mix’s very own core. Heavily relying on hybrid mastering techniques, we combine digital precision with the genuine charme of analog sound. Our work led to several platin & gold status releases and chart rankings. Convince yourself of our quality and become part of the family.
