Neptune Mastering is a professional mastering studio located in Berlin, Germany. We specialize in providing high-fidelity music mastering services to local and remote artists. In addition, we also offer full album CD mastering or master lacquer disc cutting. Our studio design, excellent mastering equipment, and experience allow us to provide outstanding audio mastering services at affordable rates.

Stem Mastering

Individual audio tracks are grouped together to allow for independent control and signal processing of each stem and can be manipulated independently from each other. Stem Mastering should only be used if there are serious problems in the final mix. Preferably you would fix these types of problems during mixdowns. If you can not go back and redo your mix Stem Mastering is the way to go.


Audio mixing skills take years to hone which can be frustratingly difficult when first starting to produce. Sometimes stereo or stem mastering is not enough to reach the outcome desired. This professional mixing service will transform your song into a tight, punchy, well-balanced, fat mix with the correct stereo width that lets all your hard work shine through.

Lacquer Disc Cutting

Lacquer cutting is the process of transforming an audio recording into physically cut grooves on the surface of a lacquer disc via a machine called a lathe. This cut lacquer is used as the master in the electroplating process to create stampers which are then used to press your album. So if you appreciate our special sound but want to handle your pressing yourself, we will be happy to take over the lacquer cut for your production.

Design & Consulting

We offer acoustic measurements, consultancy, custom design studio and home cinema rooms that are tailor-made to fit your setup and acoustic needs.
