Stem mastering is a more advanced way of mastering. With this type of online-mastering you provide us multiple stereo files of your track. Each audio file contains some single or combined elements of your mix. Those files are also called separations, layers or stems. Other types of mastering we provide are stereo mastering and multitrack mixing/mastering.
What are the benefits of stem mastering?
Stem mastering gives us the opportunity to apply changes to certain elements of the mix without affecting others. With stem mastering your track is divided into a few busses (stems) so we can apply changes to one bus without affecting the other busses. Let’s take a closer look at this.
When you have a vocal track which has some loud ssss-sounds in the vocal, stem mastering will allow us to process the vocals separately from the rest of the mix. By doing this the de-esser will only affect the vocal part without affecting the rest of the high frequencies of the mix.
Let’s assume there is too much sub in the bass line. When having some sub mixes (stems) of your track we are able to process these signals separately. So when having the bass line and bass drum in separate files we are able to EQ the bass line without affecting the bass drum.
Which stems to choose
What elements of your mix we need stems from depends on the type of music and the problems you have in your mix. As a rule you could say that we need stems of the most important elements of your track. You can also create stems from elements you think will cause problems in your mix. When it comes to vocal electronic dance music you should at least provide us stems files from:
- Bass Line
- Bass Drum
Don’t forget to make a stemfile of the mix without the Bass Line, Bass Drum and Vocals. You can name this file as “Rest Of the Mix”. So including this file you will have 4 stem files of your mix. You can send an e-mail to firstname.lastname@example.org if you need advice in what kind of submixes we need from your mix. Please also include a download link to your track so we can take a listen.
Example of stem mastering electronic dance music with 6 layers (stems): The file set of this stem mastering could look like this:
- All Synths.wav
- Rest Of The Mix.wav
