How to Mix and Master a Song

To mix and master a song, you work in two distinct stages: first you mix — balancing every individual track into a cohesive stereo file — then you master that finished mix to make it loud, polished and consistent across all playback systems. Mixing is about balance and clarity within the song; mastering is about final polish and getting the whole song to compete with commercial releases. Doing them as separate steps gives you the best results.

How to mix and master: understand the two stages

Many beginners blur the line, so be clear on the difference:

• Mixing works with all your separate tracks (vocals, drums, bass, instruments). You set levels, pan, EQ, compress and add effects to make them sit together.
• Mastering works with the single stereo file your mix produces. You apply subtle EQ, compression, limiting and loudness control to the song as a whole.

Mastering can’t fix a bad mix — if the balance is wrong, fix it in the mix. Read what is mastering for a deeper explanation of the stage.

Step 1: Prepare and gain stage your session

Organise and label tracks, then set healthy levels so nothing clips and you leave headroom (aim to peak well below 0 dBFS). Proper gain staging makes every plugin behave better and is the foundation of a clean mix.

Step 2: Build the balance

Pull all faders down and rebuild the mix starting with the most important elements (often vocals and drums). Get a rough balance with just volume and panning before reaching for plugins — a great mix is mostly good level decisions. If this is your first time, our beginner’s guide to mixing your first song walks through the order.

Step 3: EQ and compress

Use subtractive EQ to remove mud and clashes so each instrument has its own space, then compression to control dynamics and add punch. These two tools do most of the heavy lifting — see the EQ and compression fundamentals guide. Treat the vocal with care; the how to mix vocals guide covers a full chain.

Step 4: Add depth and width

Reverb and delay create a sense of space and place instruments front-to-back. Use sends rather than inserts so multiple tracks share the same space. Our reverb and delay guide shows how to set this up. Leave the mix peaking with a few dB of headroom for mastering.

Step 5: Export your final mix

Bounce the finished mix to a high-resolution stereo file (keep the same sample rate as your project) with a little headroom — peaks around -3 to -6 dBFS is fine. Don’t put a limiter on the master bus while mixing if you intend to master separately.

Step 6: Master the song

Open the stereo mix in a fresh session and apply mastering processing gently:

1. Corrective EQ — small broad moves to balance the tonal spectrum.
2. Compression — light glue compression for cohesion.
3. Limiting — raise the loudness to a competitive level without crushing transients.
4. Loudness check — target an appropriate LUFS level for streaming; see LUFS explained for targets.

If you’d rather not master yourself, online services like LANDR and eMastered can handle it automatically. For the complete picture, browse the mixing and mastering hub.

Step 7: Reference and check translation

Compare your master to commercial songs in the same genre at matched loudness, and listen on multiple systems — earbuds, phone, monitors and car. A master that only sounds good in your studio isn’t finished.

Frequently asked questions

What is the difference between mixing and mastering?

Mixing balances all the individual tracks of a song into one cohesive stereo file. Mastering then takes that single stereo file and applies final polish — subtle EQ, compression and limiting — to make it loud and consistent across playback systems.

Can I mix and master at the same time?

It’s better to keep them separate. Finish and export the mix first, then master in a fresh session. Working on the full mix with fresh ears makes mastering decisions more objective, and a clean exported file with headroom masters more easily.

Should I master my own song or use a service?

You can do either. Mastering yourself gives full control if you have good monitoring and reference tracks. If you lack experience or a treated room, automated services like LANDR or eMastered, or a dedicated mastering engineer, can deliver more reliable results.
