I’m a musician and sound engineer specialized in music mastering.
I studied music at Bass School Munich (1998-99) and sound engineering at Robert Schumann Music College and the University of Applied Sciences Düsseldorf (2000-2005).

Since 2005 I live in Berlin and work as a freelancer in many different fields – live and studio musician, recording, mixing, mastering, production, audio engineering for opera and TV.
During my work I found out that giving a piece of music its final sonic polish is the most pleasing part of audio production to me.

I love listening to music, getting to the heart of it and making it sound great on many different sound systems. Therefore I set up the ASM mastering studio in 2015.

…Wow! You’ve done a fantastic job. Thank you so much; I’m very very happy! (Ben Castle, musician/producer)

…I have been very impressed at his attention to detail, his preservation of dynamic range in program material and the musicality of his technical decisions.  All this whilst making masters which sound absolutely “full” and “energetic” compared to other masters in the same genres. (Paul Pilot, musician/producer)

Before you send me your files please keep the following in mind:

Release: If your music will be released on CD make sure to ask for a DDP file and provide me with the following information: track listing (with the right spelling of the song name), ISRC Codes, EAN Code

If you’re planning a digital release let me know if you need extra masters for iTunes/MP3/HiRes audio/streaming.

Also ask for extra versions if you’re planning a vinyl release.

Format: Let me know about the sample rate and bit depth that you have chosen for your mixes.

Versions: If you want additional versions of your song (instrumentals, TV versions, radio edits…) to be mastered please make sure to send all the files at once as I mainly work with analog equipment.

Delivery: Please send me a ZIP file containing all songs and information.

Beginnings/Endings: Leave enough space at the beginnings and endings of your song files.

Fades: Please don’t  fade song endings.

Reference Tracks: Feel free to send reference tracks but don’t forget to mark them as references.
