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

You can read about what I can do to help you create a production that will stand out sonically on this site. While my core clientele is artists working in 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 to sound.

I have a background as a musician and producer working in electroacoustics since 1990 and have released 60 albums of my music on international labels. My work has been performed at Sónar, ATP x Primavera Sound, CTM Berlin, Mutek Montreal, MITO Settembre Musica, etc. I have created site-specific sound installations for festivals, spaces, and places across four continents and worked as an 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.

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