In short: Mixing combines many separate tracks (vocal, instruments, samples) into one coherent whole. Mastering is the final polish on the finished mix — leveling loudness to the -14 LUFS standard, refining frequencies, getting the file ready for Spotify and other streaming platforms. At Flightcore, full mix with mastering starts from 500 PLN, mastering alone from 300 PLN. The typical process takes 3-7 business days.
You tracked the vocal, the beat sounds solid, you bounce the file — and suddenly Spotify spits out something that lands like a 2004 demo. The difference comes from what happens (or doesn’t happen) after recording.
Mix and mastering are two distinct stages of audio post-production. Each does something different, both are needed. We break them down without the mystique below.
What is mixing, exactly?
Mixing is the process of combining many separate audio tracks into a single coherent whole. A typical music project carries 20 tracks or more — lead vocal, harmonies, adlibs, kick, snare, hi-hat, bass, synths, samples, effects.
The engineer dials in the volume of every element, the stereo image, EQ, dynamic compression, reverb, delay, and dozens of other parameters.
The goal is straightforward: every instrument has its place, the layers work together, and the whole thing lands as one integrated track.
A professional mix on a single takes the engineer from 4 to 12 hours, depending on project complexity.
How is vocal mixing different from a full mix?
If you’re producing on a finished beat (an instrumental), the situation is simpler but still asks for precision. Vocal mixing handles up to a dozen-plus vocal tracks — lead voice, doubles, harmonies, adlibs — and seats them on top of the beat so they sit in the mix as a natural part of the song.
A single vocal can carry up to 20 separate tracks. Each takes its own approach to EQ, compression, and space. Vocal mixing is therefore a separate service — at Flightcore, from 400 PLN.
What is mastering and why do it?
Mastering picks up where mixing ends. The work happens on two tracks — the stereo mixdown (left and right channel).
It’s the final polish: setting target loudness, refining clarity, making sure the track plays consistently across every system — from 100 PLN earbuds to a 30,000 PLN hi-fi rig.
Mastering is also a quality check. The engineer catches small details that slipped past in the mix — a sibilance that’s a touch too sharp, a bass note that gets lost on small speakers, a missing breath at the top of the spectrum.
The Spotify loudness standard is -14 LUFS — mastering aligns your track to that level, so it sits at the same perceived volume as the rest of the catalog on streaming platforms.
Why isn’t a raw recording enough?
The comparison is straightforward. Take a phone photo and compare it to the same shot after professional editing in Lightroom. Technically, the same frame. In practice — two different worlds.
A raw recording works the same way.
Without mixing, the tracks pile on top of each other — the vocal gets lost in the beat or dominates everything around it. Without mastering, the track plays quieter than other songs on Spotify, sits flat on headphones, and loses bass on car speakers.
Streaming-platform algorithms normalize loudness, but they don’t repair bad balance or missing dynamics. Professional mix and mastering is the difference between “nice demo” and “this sounds like a real release.”
What does the process look like step by step?
1. Session prep
The engineer receives (or prepares) separate tracks: vocal, instruments, samples. Each track should be cleaned of basic noise and properly labeled. A standard project lands at 15-30 tracks.
2. Mix
The engineer imports the tracks into a DAW, sets up routing, groups instruments, and starts with volume balance. From there into EQ, compression, and spatial effects — iterating, comparing against references, correcting.
This stage takes 4-12 hours, depending on the project.
3. Listen-back and revisions
You get a preview to listen to. Feedback in the vein of “vocal could sit more forward” or “bass is too heavy” is expected and welcome.
Usually 1-2 rounds of revisions are needed — both included in the price.
4. Mastering
Once the mix is signed off, the engineer exports the stereo mixdown and moves into mastering. The work happens on a separate effect chain: mastering EQ, multi-band compressor, limiter, LUFS analysis.
Goal: -14 LUFS for Spotify and clear sound on every playback system. Mastering a single takes 1-3 hours.
5. The final file
You get the final file as WAV (44.1 kHz / 16-bit or 48 kHz / 24-bit), and an MP3 alongside if you need it. The file is ready to upload to streaming platforms straight away.
Can I do mix and mastering myself?
It’s worth trying. Audacity is free, Reaper costs around 60 dollars, and you’ll find hundreds of tutorials online. You’ll learn the basics, understand what EQ does, why compression changes the character of a vocal, how a limiter works.
There’s a threshold, though, that’s hard to cross at home. A professional mix asks for more than software — it asks for a trained ear (several years of regular practice), studio monitors, an acoustically treated room, and experience earned across hundreds of projects. The engineer hears problems a beginner simply doesn’t notice. The acoustics of an apartment room actively work against you.
A reasonable approach therefore: keep learning, keep experimenting, do as much as you can on your own, and hand the final mix and mastering for release to someone who does it for a living.
How much does mix and mastering cost?
Our rates at Flightcore look like this:
| Service | Price |
|---|---|
| Full mix with mastering | from 500 PLN |
| Vocal mix (on a finished beat) | from 400 PLN |
| Mastering alone | from 300 PLN |
The number depends on project complexity — track count, the state of the input material, the rounds of revisions involved. A simple single with vocal and beat is a different scope of work from a 40-track session with a live band.
For context: in the Polish market, professional mix prices start at 300 PLN and reach 3000 PLN per track, mastering 150 to 1000 PLN. The spread comes down to engineer experience, monitoring quality, and the revision scope included.
