I feel like LUFS get mentioned so often now that a lot of people start chasing loudness numbers before the mix is even truly ready.

For me, LUFS are useful, but they are not the whole story. A track can hit a loudness target and still sound flat, over-limited, or less musical than it should.

I care a lot more about whether the mix still has punch, clean transients, and enough flexibility for mastering to do its job properly.

Curious how others see it.

Do you think too many producers focus on LUFS too early?

This should work very well on Reddit because it invites nuance, not just facts.

A lot of people talk about mastering as if it begins after the mix is finished and exported.

I don’t really see it that way. For me, mastering starts before export.

It starts with the condition of the mix bus, the amount of headroom left, whether the track is over-limited, whether transients still breathe, and whether the mix is finished enough to benefit from mastering rather than still needing mix fixes.

A clean export gives mastering room to work. A clipped, overly loud, or unstable mix usually pushes mastering into correction mode first.

That is why I think the mix preparation for mastering matters more than many people realize.

What do you always check before sending a track to mastering?

A lot of people still think mastering is just about making a song louder. It is not.

A mastering engineer can improve tonal balance, loudness control, stereo consistency, transient handling, and how a track translates across different systems.

But mastering cannot fully repair clipped peaks, weak balances, heavy masking, or a mix that already feels crowded and unstable.

That difference matters more than most producers realize. I wrote a full breakdown here: https://songmixmaster.com/what-does-a-mastering-engineer-actually-fix-in-your-track

For me, mastering can absolutely improve tonal balance, loudness control, translation, stereo consistency, and final polish. But it cannot fully undo clipped peaks, weak balances, masking, or a mix that already feels overcrowded.

What do you think mastering actually fixes best, and what problems should already be solved in the mix?

I hear this advice repeated constantly, but a lot of people interpret it differently. Some focus on peak level. Some care more about LUFS. Some just avoid clipping and keep moving.

For me, headroom for mastering is really about leaving enough space so the mastering stage can shape tone, loudness, and dynamics without fighting problems that were already printed into the mix.

What do you personally watch most before sending a track to mastering?
