Our Group Stem Mix & Mastering service streamlines your project for maximum cohesion and clarity. Instead of sending 30–40 individual channels, you simply group your elements into stems such as drums, bass, percussion, pads, effects, and vocals. This focused approach allows us to work on your track in a more musical, balanced way, ensuring each section gels perfectly with the rest of the mix. The result is a polished, professional master that feels tight, unified, and ready for release. Maximum 10 stems.
Group Stem Specifications: Please send your stems either 44.1/48k 16/24 bit and preferably -10db peak, but no less than -3db peak. Stems that are red-lining or with no headroom will be rejected, and you will be contacted to provide adequate pre-masters.
