Stem Mastering Service

Professional Stem Mastering Services

In addition to our standard mastering service we also offer stem mastering for clients who want our mastering engineer to have the most control during the mastering process. For the majority of projects standard stereo mastering will provide excellent results, however for artists who prefer to give our engineers the most possible control over their mix we also offer stem mastering. Mastering from stems allows us to dive in deeper to the mix and more finely adjust frequencies and levels. It also allows us more control to correct problems in the mix that might otherwise be impossible with a single stereo file.

What Is Stem Mastering?

When mastering from stems you will submit multiple stereo tracks that have consolidated instruments. For example an artist might submit 4 stereo wav files ( One containing all guitars, one with lead vocals, one with drums, and one with background vocals, etc.. ). Our engineer would then work with each stem to set frequencies, adjust levels, and correct any imperfections. When he has finished the stems are combined and the final song is then mastered. Since we have access to separated groups of instruments there are more options for the engineer to make fine adjustments and correct problems.

How To Prepare Your Mix

Preparing a mix for stem mastering involves grouping your instruments into individual stems. We accept up to 8 stems per song, and as a general rule you want to group similar instruments together. An example set of stems would be: drums, bass, synths, rhythm guitars, lead guitar vocals, and backup vocals. The stems you submit can be separated any way that will give our engineer the best options to work with your project. As with all mastering projects we recommend leaving 3dbB of headroom and removing any pre-mastering processing from each stem. Stems should all be the exact same length and start and stop at the same time (this is crucial so the tracks line up when they’re imported and mixed together.)
