How to Mix a Song: The Order of Operations That Works

The short answer: mixing is balancing every element of a song — levels, frequencies, dynamics, and space — so the record sounds intentional everywhere it plays. The professional secret isn't better plugins; it's doing the jobs in the right order: gain staging → static balance → EQ → compression → space → automation → done. Most muddy mixes aren't missing a tool. They're missing a sequence.

I've mixed records that went to 50M+ streams through Sony, Universal, Ultra, and Dim Mak. This is the order of operations I actually use, with the checkpoint at each stage that tells you it's finished — because knowing when to stop is half the craft.

Before you touch a fader

Two minutes of setup that saves two hours of confusion:

• Pick 2–3 reference tracks in your genre and keep them one click away, level-matched. Your ears drift within minutes; references are the anchor.
• Mix at low volume most of the time. If it sounds balanced quiet, it sounds balanced loud. Loud monitoring flatters everything and lies about balance.
• Know the difference between fixing and finishing. If the sounds themselves are wrong — weak samples, clashing parts — that's production, and no mix move rescues it. Mixing vs mastering is a different line; production vs mixing is this one.

The order of operations

1. Gain staging — the boring stage that decides everything

Set every channel to a sane level before any processing — full glossary entry here. The point isn't dogma about numbers; it's that every plugin you add later behaves predictably when it's fed sensible levels, and your master bus keeps the headroom that mastering will need.

2. Static balance — the stage everyone skips

Faders and pans only. No EQ, no compression. Get the song sounding as good as possible with level and placement alone. This is the highest-leverage stage in all of mixing: a great static balance sounds 80% mixed, and every plugin afterward becomes a refinement instead of a rescue. If you can't get the vocal sitting right with just a fader, EQ won't save it — the arrangement is too crowded, and that's a production fix.

3. EQ — subtraction first

The core move: cut the frequencies an element doesn't need so the element that DOES need them can have them. Kick and bass negotiating 40–100 Hz. Vocals owning 1–4 kHz while synths step back. Mud living at 200–400 Hz on almost everything — cut it there before boosting anything anywhere. Boosts are seasoning; cuts are the meal. (EQ fundamentals if the tool itself is new.)

4. Compression — with a reason, every time

Before every compressor, say the reason out loud: taming a wild vocal, adding punch to drums, gluing a bus. No reason, no compressor. Start gentle (2–4:1, a few dB of reduction), and remember the OTT lesson: density-on-everything makes mixes loud and small at the same time. Per-bus glue beats per-channel crushing.

5. Space — depth is a dimension

Reverb and delay put elements in front or behind; width puts them left and right. Two or three shared reverbs on sends beat a different reverb per channel — shared space is what makes a mix sound like one room instead of twelve. Keep the low end close to mono, check the mix in mono after every width move, and use pre-delay so vocals stay in front of their own reverb.

6. Automation — where mixes become records

Static mixes sound like demos. The last 10%: ride the vocal up 1 dB into the hook, pull the pads down when the vocal enters, open a filter into the drop, cut everything for one beat before the chorus. This stage is taste, not tools — and it's the one AI mixing can't do, because it requires knowing what the song means.

7. Stopping — the real skill

Signs you're done: the references A/B favorably at matched volume, it translates on earbuds, phone, car, and your last five tweaks were reversals of the previous five. Bounce at 24-bit with ~-6 dB of headroom, no limiter on the master — that's the handoff mastering wants.

Quick answers

How long should mixing a song take? Beginners: sessions across several days (ear fatigue is real). Experienced: 4–8 focused hours for most electronic records. If you're 40 hours in, you're producing, not mixing.

Should I mix while producing or after? Rough-balance while producing, real mix after the arrangement locks. Mixing a moving target is how projects die.

Can a great mix skip mastering? No — they're different jobs on different timescales. A great mix makes mastering easy; it doesn't replace it.

Do I need expensive plugins to mix well? No. Every stage above works with stock plugins. The order and the decisions are the product; the tools are interchangeable.
