I offer a comprehensive mastering service. Besides the classic single mastering for online distribution, I offer mastering for EPs and albums, both for online and for physical media like CD or Vinyl. I also take care of the creation of DDP images, implementation of ISRCs, embedding of meta data and more. As a certified provider I am also able to create an Apple Digital Masters suitable mastering.

I work with selected high-end hardware devices as well as with industry standard plug-ins. In my work the emotion of the music is always in the foreground and my goal in every mastering process is to create a connection between the music and the listener.

As a longtime lecturer for audio engineering at SAE Institute, WAVE AKADEMIE, Akademie-Media and other schools and as a Steinberg Certified Trainer I have a lot of experience in teaching.

I offer courses in mastering as well as private lessons on mixing and mastering and Steinberg software products like Cubase and Wavelab.

If you are interested in these offers, just write me an email or use the contact form.

Since the beginning of 2023 I offer a mastering course, which lasts a total of three days and is intended for people who already have previous experience in this field. You will find more information about the SMR MASTERING COURSE here.
