about me

Between 2001 - 2014 I produced classical music recordings, co-running Legato Recording. Those years and the outstanding musicians I was lucky to hang around with, helped me look inside myself and decide to devote my professional life to audio mastering.
I learned the art of mastering from two of the most respected engineers in the business - Howie Weinberg (Nirvana, Garbage, The Cure) and Vlado Meller (Lou Reed, Michael Buble, Celine Dion), during extensive masterclasses in Holywood, LA.
Owing to the experience I’ve gained working in the various fields, my interest in the theatre, modern art and alternative music, I constantly discover new microcoms. This helps me comprehend the artist’s intentions but keep a critical distance and a fresh approach which are indispensable in audio mastering.

The studio is located halfway up Francuska Street, in Warsaw’s most beautiful district Saska Kępa.
It was entirely designed by Arek Szweda from Sveda Audio. Thanks to the optimal dimensions of the room and thick, brick walls of a pre-war tenement house combined with Arek’s acoustic engineering knowledge and his passion for high quality sound, a studio with unprecedented acoustics was created - the linearity of the frequency characteristics, resolution, the location of elements in the acoustic space and the width of the stereo image are unmatched.
