Mastering by Stems makes it possible to improve the sound of your works.

If the mixing of your work is to your complete satisfaction in all its components (dynamic, EQ, spatialization, etc.), then a classic stereo mastering is sufficient.

However, if as in the majority of cases, the mixing of you work suffers from a few flaws, compromises will need to be made if resorting to a classic mastering, in order to correct those flaws to obtain the best result possible.

For example, let’s say that you mixed an audio recording and you realize that a certain degree of achievement is possible and that some imperfections need to be corrected:

  • Voice not present enough, too sibilant
  • Sound texture of the voice or of an instrument needs optimizing
  • Too many sharp notes for an instrument
  • Not enough or too much resonance
  • Balance to improve in the register of low frequencies (bass, bass drum, etc » …)

In those cases, a mastering by stems would have made it possible to obtain much better results than a classic mastering, because these technical problems do not have perfect solutions when it comes to a classic mastering.

With a mastering by Stems, several problems which have been identified can be corrected without this affecting (or to a negligible degree) the other elements of your work.

Variation of classic mastering, the mastering by Stems consists of:

  • Integrate different parts of your recording tracks by theme or groups of instruments (Stems) such as: voice stems, percussive stem, bass stem, etc. and to integrate them in a coherent whole that will maximize the range of each portion of the recording.
  • Each group of instruments will be dealt with separately: dynamic, EQ, spatialization, etc.

Thanks to this procedure, the sound quality is improved, more balanced and more harmonious because all the mistakes from the original mix are corrected.

The results?

A work with a rich, harmonious and balanced sound, which surpasses the quality of the original mix.
