The Stem Mastering Workflow: When and How to Use It

Stem mastering processes grouped stems — typically vocals, drums, bass, and instruments — separately before summing them through a final mastering chain. It bridges the gap between mixing and stereo mastering.

When to Reach for Stems

• The vocal sits too far back or too forward in the mix.
• The low end is muddy and stereo EQ would damage the rest of the spectrum.
• You need maximum loudness without crushing dynamics.

Prep Tips

Bounce stems at the same length, with the same start point, and at 24-bit. Leave at least 6 dB of headroom on each stem so the mastering chain has room to work.

FNLZ Studio masters stereo mixes. If a stem needs fixing, fix it in the mix, then upload the balanced stereo bounce for mastering.
