Key Highlights
Mixing and mastering are two completely different processes; one happens inside the track, the other prepares the final result for the world.
Mastering a bad mix doesn’t fix the mix; it makes the problems louder. The order matters as much as the processes themselves.
It’s not about volume or loudness. It’s about decisions that determine how your music translates everywhere it’s heard.
Two of the most common questions we hear from independent artists:
“Do I need both mixing and mastering or just one?”
“Can I just master it myself once the mix sounds good?”
The fact that these questions come up so often tells you everything about how poorly this part of the process is understood and how much it costs artists who get it wrong.
Here’s the plain-English version.
What Mixing Actually Is
Mixing is everything that happens inside the track before it becomes a finished stereo file.
Every element you recorded or produced, vocals, instruments, samples, beats, exists on its own track in your session. Mixing is the process of making all of those elements work together. Volume levels, EQ, compression, reverb, stereo placement, automation, all of the decisions that determine what the listener hears and when.
A good mix makes everything feel intentional. The vocal sits clearly in front of the music without fighting it. The low end has weight without muddying the midrange. The different elements occupy their own space, so nothing is competing with anything else. When you close your laptop and listen to your phone speakers, it still sounds like the same song.
That last part is the real test. A mix that only sounds good on studio monitors isn’t a finished mix. It’s a starting point.
What Mastering Actually Is
Mastering is the process that happens after the mix is done.
You take the finished stereo mix, the single audio file that came out of the mixing process, and prepare it for distribution. That means optimizing the overall loudness and tone, making sure it translates correctly across different playback systems, meeting the technical specifications of wherever it’s going (streaming platforms, broadcast, sync libraries), and ensuring it sounds consistent with your other releases, etc.
Mastering is also where you catch anything that slipped through the mix, such as a frequency buildup that only shows up on certain speakers, a True Peak level that’s too high for broadcast, or a stereo issue that creates problems in mono, etc.
What mastering is not is a fix for a bad mix. A mastering engineer can do a lot. They cannot balance your vocals against your beat, add depth to a flat arrangement, or fix a low end that was wrong from the session. Those are mix decisions. Once the mix is printed and handed to mastering, those decisions are locked in.
Why the Order Matters
The correct order is always: produce + mix + master = distribute.
Every step depends on the one before it being done properly. Skipping a step or doing them out of order doesn’t save time; it guarantees a worse result at every stage that follows. No bueno!
One of the most common versions of this mistake is artists who produce and mix themselves, then send the track straight to distribution or submission without mastering. The track is never optimized for the platforms it’s going to. The loudness is wrong. The stereo image isn’t checked. The True Peak hasn’t been controlled. On some systems, it sounds fine. On others, it falls apart.
The second most common version is the opposite: artists master their own mix using a plugin or an automated online mastering tool before the mix is actually finished. The mastering process bakes in whatever problems existed in the mix and makes them significantly harder to address later.
What Professional Mixing and Mastering Actually Changes
The difference between an unmixed track and a professionally mixed one isn’t subtle to trained ears, but it’s also not always obvious to artists who have been listening to their own music for weeks, over and over again.
What changes in a professional mix:
The vocal finds its place. The low end becomes intentional rather than accidental. Elements that were fighting each other stop fighting. The emotional arc of the song, the build, the release, and the impact of the hook are supported by the production rather than working against it.
This is where AI-to-Human Production is also important. Giving the song emotion.
What changes in a professional master:
The track is ready for wherever it’s going. It plays at the right loudness on Spotify, for example, without getting turned down. It passes broadcast specifications. It sounds like it belongs next to the other tracks in a playlist rather than coming from a different world.
Together, mixing and mastering are what separate a track that sounds like it was made in a bedroom from one that sounds like it was made in a studio, even when both of them were made in a bedroom.
**Note: Absolutely nothing wrong with a bedroom production!
The Bottom Line
Independent artists who skip mixing, rush it, or treat mastering as a substitute for it are leaving the most controllable part of their track’s quality on the table.
If you’re not sure where your mix and master stand, or whether what you have is ready for submission, that’s a conversation worth having before you send it anywhere.

Frequently Asked Questions
- Can I mix and master my own music?
Yes, and many artists do, with varying results. Artists who produce their own music are evaluating their mix with the same ears that made it. Objectivity is hard to maintain after you’ve heard the same track two hundred times. Professional mixing and mastering isn’t just about technical execution; it’s about a fresh set of trained ears making decisions your ears can no longer make objectively. - What’s the difference between mixing and mastering?
Mixing a track happens in the session, balancing, shaping, and arranging the track’s individual elements. Mastering is the process of taking the finished stereo mix and preparing it for distribution. This is all in simplest terms. At Fuster Studios, we handle both as part of the production process, which means the decisions made in the mix inform the mastering and vice versa. - Do I need professional mixing and mastering if I’m just putting music on streaming platforms?
The streaming platforms themselves don’t require it; they’ll accept an audio file that meets their basic technical specs. But the listeners do. Your track will be played alongside professionally produced, mixed, and mastered music. The difference is immediately audible to anyone who’s listening. If you want your music to compete for streams, playlist placement, or sync submissions, it needs to be at the same level as what it’s competing against. - How do I know if my mix is ready for mastering?
A mix is ready for mastering when it sounds as good as it can sound on multiple different playback systems, monitors, headphones, phone speakers, and car stereo, and when there’s no single element that’s clearly wrong. If you’re still hearing things you want to fix, the mix isn’t done. Sending an unfinished mix to mastering is one of the most common and costly mistakes in independent music production. - What’s the typical turnaround for professional mixing and mastering?
It varies depending on the scope of work and how many revision rounds are needed. At Fuster Studios, we build realistic timelines into every project from the start, so artists know exactly when to expect delivery, and so there’s time to do it properly rather than rushing to a deadline.
