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.

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

 About me  

I have a background as a musician and producer working in the field of electroacoustics since 1990 with 60 records and CDs of my own music released on international labels, as well as on my Schwebung imprint.


I have presented my music at Sónar, ATP x Primavera Sound, CTM Berlin, Mutek Montreal, MITO Settembre Musica etc, created site-specific sound installations for festivals, spaces and places across four continents and worked as associate professor for Sound in several international institutions.


My involvement with mastering goes back to 1998, when I worked as an engineer in a classic electronic music studio and got commissioned with digitizing their archive of analog reels and DAT recordings of contemporary classical and electroacoustic music.


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