How to Master a Remix
Published · updated · by Loopin
A remix built from someone else's stems often carries mismatched tone and level from the original production. Mastering's job is making it sound like one cohesive record, not a collage.
Check tonal consistency between original and new elements
Vocal stems from the original often have a different tonal character than the new instrumental you've built around them — brighter, darker, more compressed. Before final mastering, do an EQ pass matching the vocal's tone to sit naturally in the new arrangement rather than sounding pasted on top.
This is usually a bigger factor in whether a remix sounds professional than any mastering decision that comes after it.
Genre-match the loudness to where the remix is going
An EDM remix of a pop song should generally master closer to EDM loudness conventions — often −7 to −9 LUFS integrated — rather than the original's loudness, since it's now living in a different genre context with different listener expectations.
Think about where the remix will actually be played — a club set, a streaming playlist — and master toward that context rather than defaulting to whatever the source track used.
Watch the low end carefully with new bass elements
A new bassline or 808 added under an existing vocal can easily clash with low-end content already present in the vocal stem, creating buildup that wasn't a problem in the original mix. Check the 60–150 Hz range specifically for congestion between old and new elements.
A high-pass on the vocal stem around 100–120 Hz, if it isn't already applied, usually clears most of this without needing aggressive processing on the new bass.
Bring cohesion with a light overall glue
A gentle bus compressor across the full mix, doing just half a decibel to a decibel of work, helps different-sourced elements feel like they're playing in the same room rather than sitting on top of each other. This isn't about loudness — it's about cohesion.
If the remix still feels like separate pieces after this, the issue is more likely arrangement or tonal matching than something mastering alone can fix.
Reference against remixes in the same style
Pull up a released remix in a similar genre and compare energy, loudness and overall cohesion at matched levels. A remix that holds up in that comparison is properly mastered, regardless of how different the source elements originally were.
This is a more useful check than comparing back to the original track, since your remix is now competing in a different genre's listening context.
Frequently asked questions
How loud should a remix be mastered?
Match the genre you're remixing into, not the original track's loudness. An EDM remix commonly masters around -7 to -9 LUFS integrated, since it's now living in a different listening context with different expectations.
Why does my remix sound like separate pieces instead of one track?
Usually a tonal mismatch between the original vocal stem and the new instrumental. EQ-match the vocal to sit naturally in the new arrangement, and add a light overall bus compressor for cohesion.
How do I stop a new bassline clashing with the original vocal stem?
Check the 60-150 Hz range for buildup between the two, and high-pass the vocal stem around 100-120 Hz if it isn't already -- this usually clears most low-end clash without needing to process the new bass aggressively.
