Music Mastering. High quality. Good service.



There are two different options for getting your mastering done:

Standard Mastering

The standard form of mastering using a single
pre-master mix. Also with the option of splitting the pre-master in two files; instrumental and vocal. For a little bit of extra flexibility.

Stem Mastering

A more extensive form of mastering where the
pre-master mix is split into multiple stems. This was you can go deeper into editing levels and balances.

How does it work?

  • When I receive the premaster file we will talk about what the song needs and if the mix is master-ready.
  • Then I will do my thing and deliver the first version (usually within 48 – 72 hours, I don’t want to rush the master).
  • After the first version you will have 5 revisions (included) to get to the final version.
  • When the final version is approved you will receive the means of payment and a download link to your files that are ready for upload.
