Mastering from stems helps achieving precisely balanced results without affecting the creative mixing decisions.

With access to the stems, the mastering engineer can adjust:
– precise dynamics of individual stems
– spectral balance between stems
– (un)wanted resonances

delivery format

Prefered stem delivery format is:
96kHz 24bit WAV

All the stems are exported with their appropriate processing and without gain normalization, so when you play all of them together into the mix bus (with mix bus processing), it will sound exactly the same when playing individual tracks.

The group playback of stems will be quieter than the exported mix bus, without clipping, and without any mix bus processing applied.

Stems can be:
– groups of sounds (drums, lead vocals, backing vocals, synths, guitars, etc.)
– effects returns (delays, drum room, lead vocal reverb, etc.)

additional information

To get as close as possible to the intended expression of the artist, it is very helpful to also supply:
– finished “loud” version of the mix with all the processing from the mixing engineer
– the original rough mix from the artist, if available
– examples of the artist’s favourite songs of similar genre
– examples of the artist’s favourite great-sounding songs of other genres
