Take Your Tracks to the Next Level With Stem Mastering

Stem mastering offers greater flexibility and precision than traditional stereo mastering. By working with individual stems (such as vocals, drums, bass, and other elements), we can fine-tune each part of your track for the perfect balance, clarity, and impact. Whether you’re looking to enhance dynamics, tighten the mix, or add creative polish, our Stem Mastering Service delivers professional results tailored to your vision.

What Is Stem Mastering?

Unlike traditional mastering, which works with a single stereo mix, stem mastering involves multiple audio stems (subgroups of your track, such as vocals, drums, bass, or synths). This allows us to:

  • Make precise adjustments to individual elements of your track.
  • Correct mix issues without compromising the overall sound.
  • Add depth, clarity, and polish to achieve a professional finish.

Our Stem Mastering Process

  • Upload Your Stems
    Send us your track’s key stems (up to 8) via WeTransfer. Typical stems include:

    • Vocals
    • Drums
    • Bass
    • Synths/Keys
    • Effects/Background Elements
  • Analysis & Optimization
    We analyze each stem for balance, EQ, dynamics, and overall compatibility within the mix.
  • Precision Enhancements
    Adjustments are made to individual stems to refine tone, dynamics, and stereo imaging.
  • Final Mastering
    The mastered stems are combined into a cohesive stereo file, optimized for your intended platform (streaming, vinyl, etc.).
  • Preview & Approval
    We provide a preview of the master for your feedback. Revisions can be requested to ensure your satisfaction.
