Welcome to Schwebung Mastering, a studio operated by Stephan Mathieu, specialized in preparing audio for analog and digital products, streaming media, and the restoration of archival material.

On this site you can read about what I can do to help you with creating a production that will stand out sonically. 

While my core clientele are artists working in the fields of electronic, electroacoustic and contemporary classical music, I have collaborated with producers running the gamut of modern recorded music. Many clients have chosen to work with me due to their appreciation of my artistic sensitivity for sound.

I have a background as a musician and producer working in the field of electroacoustics since 1990 and have released 60 albums and EPs of my music on international labels, with several of them garnering praise in international magazines. My work has been performed at Sónar, ATP x Primavera Sound, CTM Berlin, Mutek Montreal, MITO Settembre Musica, etc and I have created site-specific sound installations for festivals, spaces and places across four continents and worked as associate professor for Sound in several international institutions. You can read more about my approach to mastering  here 

I'm operating Schwebung Mastering from the HICOG Estate heritage site in Bonn, Germany as a member of the German Tonmeister Association.

Contact me if you have questions, to discuss your project or request an individual quote, I look forward to hearing from you.
