Should You Master With a Reference Track Online? When It Helps
Published · by Loopin
A reference track is a ruler, not a recipe. It helps when it matches your genre and tempo, and it hurts when you chase its loudness or its sound at the cost of your own mix.
Pick one reference that actually matches
Choose a commercial track in your genre with a similar arrangement, such as sparse trap vs sparse trap, not a dense rock single. Download the best file you can: a lossless version, not a low-bitrate rip. Add it to your session next to your mix. Import it at its native sample rate and trim the intro so your loudest section lines up with its loudest section; that way a single keystroke swaps between them.
One reference is enough. Three references pull you three ways and you end up chasing all three. Our primer on what a reference track is covers choosing it. Skip references from a different decade or a different vocal style; the gap will only frustrate you.
Level-match before you compare anything
If your reference is louder you will hear it as better. Turn it down until the loudest section sits at the same perceived level as yours, then switch between them. A matched A/B shows what is actually different: bass weight, top-end air, vocal level.
Loopin’s own Original vs Mastered A/B is loudness-matched, so master the track free and use that for before and after. Then match your reference by hand against the master. Keep both files at the same sample rate in your session so nothing is converted on playback, and always compare the same 20-second section.
Check three spots, then stop
Listen to the kick and bass in the first drop, the vocal in the first verse and the hi-hats in the busiest chorus. Write one word each: more, less or same. If all three say “same”, you are done.
If the low end says “less” on both phone and headphones, fix the mix and run it again. If the top says “less”, try the Crisp feel. If everything says “less”, you are comparing loudness, so re-match. Check the result on a phone speaker last, because that is where a streaming-era listener will hear it first.
Do not chase the reference’s loudness
Loud commercial masters are often made for a different era or format. On streaming, loud tracks are turned down: Spotify’s artist page says negative gain is applied so playback sits at −14 LUFS. Matching a −7 LUFS reference gets you a flatter master and no advantage.
Loopin’s default export is about −14 LUFS with a −1 dBTP ceiling; Punchy is about −11 and Club about −10 if you want a hotter cut. Pick the feel that sounds right at matched volume. If you cannot decide, pick the quieter option and move on.
Know what a reference cannot do
A reference shows the target; it cannot repair a mix that is missing it. If your 808 and kick are fighting, matching a reference’s master will not fix that. Go back to the mix, and check your listening method with how to A/B your master properly. Keep that boundary clear in your head: a reference tells you where you are, never how to get there.
Automatic mastering takes no creative direction and does not copy a reference, so use the reference as a judge. For a release that has to hit a specific target, ask a human mastering engineer and send them the reference. Or run it through the free masterer first so you both start from a clean draft.
Frequently asked questions
Should I master with a reference track?
Use one as a ruler to judge balance at matched volume. Do not copy its loudness or tone; check kick and bass, vocal and top end, then stop.
Does Loopin match a reference track?
No. Loopin masters your stereo mixdown in one of eight feels. Use a reference yourself to judge the result.
How do I level-match a reference?
Turn the louder file down until the loudest section feels equal, ideally with a loudness meter. About 1 LU difference is enough to mislead.
What loudness should I match?
For streaming, about -14 LUFS. Louder masters are turned down by services such as Spotify, which applies negative gain to bring them to -14 LUFS.
How many reference tracks do I need?
One close match is enough. A second from a different era can help for loudness context, but more than two will confuse the decision.
Can a reference track fix my master?
No. It shows the target balance and loudness, but fixing a gap means changing the mix or choosing a different feel, then checking again at matched volume.
