Stem Mastering gives you more control and flexibility than traditional stereo mastering — without committing to a full mix revision.
By working from grouped stereo stems instead of a single two-track file, I’m able to make targeted adjustments to key elements like vocals, drums, bass, and music to improve balance, clarity, and impact in ways that aren’t possible in stereo mastering alone.
This is the ideal solution if your mix is close… but needs that extra level of polish to compete commercially.
What You Can Submit
You can provide 2–4 stereo stems containing the core elements of your mix. Common submission formats include:
• Music + Vocals
• Drums + Bass + Music + Vocals
• Instrumental + Lead Vocals + Background Vocals
All stems should be fully mixed within their groups and exported to start at the same point for proper alignment.
What’s Included
Stem-Level Processing
Independent tonal and dynamic control over major mix elements.
EQ & Dynamic Control
Precise frequency shaping and compression across stem groups.
Peak Limiting
Transparent limiting to prevent distortion while achieving competitive levels.
Stereo Enhancement
Depth and width processing while maintaining mono compatibility.
Loudness Optimization
Streaming-ready level balancing without crushing dynamics.
Submission Guidelines
To ensure optimal mastering results:
• Submit all files as .WAV format
• Export at your session’s native sample rate & bit depth
• Remove any mix-bus limiting before export
• Leave 3–6 dB of headroom
If your rough mix used a limiter:
Please remove it before printing your stems, but include a screenshot of the limiter settings for loudness reference.
All stems must be time-aligned and start at the same bar.
Who This Is For
This package is perfect for artists and producers who:
• Like their mix overall but want more polish
• Need better vocal-to-instrument balance
• Want more punch or clarity without remixing
• Don’t want the cost of full mixing
You retain your creative decisions — while gaining mastering flexibility.
Revisions
Your Stem Mastering package includes:
• 2 complimentary revisions
Most projects are finalized within one revision, but if further tweaks are needed:
• Additional revisions: $20 per round

Stem mastering has been the best thing for my music!! Not only is the quality of my music amazing, but the price is unmatched.
The biggest benefit is the ability to fix my mix issues without starting over! If my vocals feel buried or my bass lacks punch, stem mastering allows for targeted adjustments without affecting the entire mix.
This is especially important in reggaeton music, where tight drum patterns and clear vocals are crucial.
My guy Matty is a BEAST when it comes to mastering tracks!!
For anyone with a tight budget looking to take their tracks to the next level, stem mastering is the way to go!!! 💯 percent

The skills, knowledge, ears, and experience that Matty Harris brings to the table are top-tier! To be at Matty’s level and still have the passion and mission to remain accessible to indie artists and labels is commendable and admirable.
I have used the stem mastering service for 15 tracks across three different artists and genres. Every single time, Matty delivers perfection. The cohesiveness, depth, and fullness he brings to each track are magical. Additionally, hearing how Matty works with the stems to elevate the music has been an educational experience in itself. Thank you Matty Harris!
