What does a mastering engineer do?

    Only when these points are correct, the audio engineer is actually able to produce Mastering Previously we would refer to this as sum editing.

  • The mastering engineer usually edits the finished mix down of a music production or works on stems. The changes made are usually minimal, as the character of the song is already determined in the mixing, by the mixing engineer and the artist.
  • The mastering engineer is the last link in the production. They improve the basic quality of the track, edits entire albums until they are duplicated or creates DDP images. Mastering for streaming platforms also plays an important role here, as the amount of songs made available online continues to increase.
  • The mastering engineer also gives feedback to the mixing engineerif there are mistakes in the mix that cannot be corrected in mastering.

Mixing engineer, audio engineer, mastering engineer - what are the differences?

The term audio engineer is usually used as a generic term for professional work on audio or sound material. However, the spectrum of activities within a music production is so gigantic that it is worth breaking down a little further here.

Mixing and mastering engineers work hand in hand to achieve the ideal sound of the song.

First and foremost, the mixing engineer deals with the mixing ratio of the individual instruments, creates a tonal balance within the song and thus ensures a pleasant mix.

Ideally, the mastering engineer's work enhances the previous steps of the "mixer", eliminates slight inconsistencies within the frequency response and prepares the audio material both musically and technically so that it reaches a professional level and can compete with other productions.
