Stem mastering is where a number of grouped instruments such as the drum subgroup, bass subgroup, leads, vocals and/or effects are treated to individual processing to enhance their overall sound.
A typical example would be a drum subgroup supplied as a single stereo audio file. We would repair any technical issues with the loop and treat it to processing via hardware to add depth, warmth, punch, and air to the audio.
We can also sum individual drums, bass and leads into grouped stems using Tube-Tech, Neve or SSL summing mixers.
Please upload your stem in 44.1kHz or higher, 24-bit .wav or .aiff. We cannot accept MP3 or any other format due to the compression
