How to Know When Your Mix Is Ready to Master

One of the most common questions independent artists ask is: how do I know when my mix is actually finished? It is a fair question. There is no alarm that goes off. No notification. Just you, your headphones, and a growing sense of uncertainty about whether the track is ready to move forward.

Here is a straightforward way to think about it.

Mastering cannot fix a bad mix

This is the most important thing to understand. Mastering works on the stereo mix as a whole — it cannot separate your vocals from your kick drum or fix a muddy low end that was baked in at the mixing stage. If the mix has problems, mastering will make those problems louder and more obvious, not less.

So before you send anything for mastering, the mix needs to be in a place where it sounds good — not perfect, but genuinely good.

Signs your mix is ready

Here are the things to check before you consider the mix done:

• Every element has its own space.
  Nothing is fighting for the same frequency range. Vocals sit clearly above the music. The low end is controlled and not competing with itself.
• The balance holds up on different speakers.
  Check it on headphones, on a phone speaker, in the car. If the mix translates reasonably well across all of them, that is a good sign.
• You have left headroom.
  The mix should peak somewhere around -6dBFS or lower. If it is already hitting 0dB before mastering, there is no room left to work with.
• You have stepped away and come back.
  Fresh ears catch things tired ears miss. If you have been working on the mix for hours, sleep on it and listen again in the morning.
• You are not making changes anymore — just second-guessing.
  There is a difference between fixing a real problem and endlessly tweaking because you are not sure. If the changes you are making are getting smaller and smaller, the mix is probably done.

What to send

When you are ready, export a stereo WAV at the full resolution you have been working in — usually 24-bit, 44.1kHz or 48kHz. Do not add a limiter to the master bus before exporting. Leave -6dBFS headroom intact so there is something to work with at the mastering stage.

If you are unsure whether your mix is ready, send it over anyway. I will take a listen and let you know where things stand before any work begins.
