Stem Mastering or (Separation Mastering)is a mastering process whereby the engineer will master a song, not from a stereo mix but from a small group of sub-mixes, i.e. a vocal mix, an instrument mix, and a drum mix. When done properly it can be a more versatile solution to professional mastering because it gives the engineer more control of song components. For instance, the mastering engineer can now apply equalization to a sub-group (or stem)without affecting the entire mix.
Separation mastering is often helpful in cases where the mixing engineer is unable or does not have the equipment to achieve a particular mix.
