ABSTRACT
A mastering engineer can be seen as an executive engineer with super trained ears. He uses specialized equalizing (EQ), compression and other equipment to fine-tune the tonal balance of the mix. The resulting production master can then be sent to a CD factory, a vinyl pressing plant or online distributors. As the mastering engineer works with a finished stereo mix, there are limitations to what can be achieved. Although a specific EQ setting can be beneficial for one instrument, other instruments might suffer. The mastering engineer knows about the mixer’s specific preferences, while the mixer can anticipate for mastering by leaving out certain processes, or stick to certain levels. In consultation with the mastering engineer, a so-called stem mastering can be a good alternative to regular mastering. The mastering engineer will import the separate files of, for instance, drums, bass, guitars, keys and vocals into his workstation and make a mix.
