A Native Instruments Stems master can be ordered as an extra option along with stem mastering or multitrack mixing/mastering. When you order this option along with your regular online mastering you must provide us with at least 4 stereo audio files (stems/separations) of your track. Each audio file contains some single or combined elements of your mix. With Stem files you give the DJ an unique tool to play your music in a creative way.
What is Stems?
Stems is a new format of audiofile that enables the DJ to be more creative during his performance. Using Stem files it’s possible to split the track into 4 individual musical elements. During a live set a DJ can turn these musical elements on and off separately. This will result in numerous possibilities for the DJ, like using the vocals of one song and the beats of another.
A Stems file consists of 4 stereo stem-tracks and a 5th track for the stereo downmix. Each track consists of one ore more combined elements of a song. The Stems file is saved in the .mp4 format. So one mp4 holds the 4 stems and a stereo master of the song. The stereo master inside the mp4 can be played with players that can handle the standard mp4 specs such as I-Tunes. Music in the Stems format is released on popular download platforms like Beatport and Juno. At the moment Stemfiles are sold in a higher price range than stereofiles. So they generate more income for labels and music producers.
Mixing with Stems
To mix with stems a hardware controller can be used for “hands on” control. While the track is playing you can lower or raise the volume of the 4 musical elements.
It’s also possible to play a track without the melody. Or without the drums for instance. By bringing different elements in and out of the mix you can create your own mash ups live. Therefore mixing with Stems is becoming more popular. It’s expected that more software and hardware will be available on the market that will support the playback of mp4 Stem files.
Which stems to choose
A Native Instruments Stem file can hold up to 4 separate (stereo) elements of your song. Bass, Drums, Vocals and Melodie is a common format for a song with vocals. For instrumental songs you can use the vocal stem for other elements of your song.
So you need to send us at least the above mentioned stems. However, you can decide to send us some more stems. This will benefit the mastering procedure.
Example of stem mastering electronic dance music with 7 stems :
When it comes to vocal electronic dance music you could send us the following stems:
Rest of the mix
The “Rest of the mix” stemfile is a wav that holds the elements of your track that are not included in the other stems. So including this file you will have 7 stem files of your mix. You can send an e-mail to email@example.com 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. If possible, send us a SoundCloud link.
After mastering we will mix the 7 stems back to 4 stems
How to prepare your music for Stems mastering?
It is easy to render the Stem files that we need for the mastering. Just follow the steps below.
Decide which stems you want to be able to play separately in the mp4 Stems file. Also consider sending more stems for mastering reasons.
To create one stem just render your project with the desired instrument in solo.
Or mute the tracks that you don’t want to hear in the stem that you are creating.
Bypass limiting and compression plugins that you have used on your master bus.
Disable noise shaping and dithering.
Make sure the output does not clip after disabling the plugins on the master bus.
Peak levels between -12 and -0,1dB are fine.
Bounce your stems as wav or aiff at a minimum resolution of 16 bit /44.1khz.
After you have rendered all the stems check if nothing went wrong. Do this by importing the stems in your DAW.
Hit playback and listen if you still hear your complete mix without errors.
