6 Mixing Mistakes That Are Destroying Your Tracks

Learning to mix is tough. There are hundreds of plugins to master, thousands of articles to consume, and only so many hours in the day.

While there’s no shortcut to mixing mastery, there are several pitfalls worth avoiding along the way. Steer clear of the following six mistakes, and you’ll be well on your way to mixing like a pro.

1. Misusing the Solo Button

The solo button is the most dangerous button in your DAW. Remember—your goal as a mixer is to take a group of tracks and make them work together. But the solo button makes doing this nearly impossible.

Every time you solo a track, your focus shifts from making it fit within the mix as a whole, to making it sound great in isolation. But nobody listens to a song by soloing individual tracks. You shouldn’t either.

In fact, good mixing decisions often make tracks sound worse in solo. Think about it…we filter down tracks to make them smaller, add excessive amounts of top end to make them cut, and EQ out chunks to make space for others. You’d never make these kinds of decisions in solo!

The solo button removes the context you need to make the right choices. The less you use it, the better your mixing decisions will be.

2. Monitoring too Loud

At high sound pressure levels (SPLs), your ears quickly become fatigued. Your speakers start to fold—compressing and saturating your mix. It’s much more tempting to kick back and listen for pleasure. After all, everything sounds so damn good when you turn it up! For these reasons, it’s hard to craft a great mix at loud levels.

Instead, try to do the majority of your mixing at low-to-moderate volumes. You’ll be able to mix longer without fatigue. And you’ll work harder to create clarity and punch within the mix, instead of being fooled by the pseudo-impact that comes from turning the speakers up. Yeah…I know it’s not as fun, but if Chris Lord-Alge can do it, so can you.

3. Over-Mixing

The process of mixing follows the law of diminishing returns. When you start, you can make considerable progress quickly. But as time goes on, your rate of progress slows. And then suddenly, you hit a wall. The mix stops getting any better.

You can certainly continue working beyond this point. Many do. But it’s useless to do so. In fact, you may end up making your mix worse. Learn to recognize this moment. When you hit it, it’s time to click “Bounce to Disk.”

4. Mixing Mindlessly

Every mixing decision we make should be a reaction to what’s coming out of our speakers. While this seems obvious, we don’t always follow it.

Instead, we pile on plugins based on so-called “rules,” whatever worked on our last mix, or whatever works for some top-tier mixer. We fix issues that don’t need to be fixed. We solve problems that don’t need to be solved. We are being proactive, instead of reactive.

All this mindless mixing is destroying your tracks. So, it’s critical to remain reactive during the mixing process. Every time you add a new plugin, ask yourself: “Why am I doing this?” If you don’t have a good answer, you probably don’t need the plugin.

5. Crushing the Mix Buss

As streaming emerges as the leading platform for music consumption, it’s even less compelling to over-limit your mixes.

Why? Because most streaming services (including Spotify, YouTube, and Apple Music) apply volume normalization to their entire catalog by default. Loud tracks get turned down, while tracks with headroom to spare get turned up. (Yes, this means your mom’s favorite Norah Jones album will be played back at the exact same volume as Metallica’s Death Magnetic.)

In this new, volume-normalized world, dynamics win. Over-limiting your mixes is pointless. And a word to the wise—be very careful about adding a limiter to your master bus early in the mixing process. Since every decision you make will be influenced by it, you won’t be able to take it off later. It will become a permanent part of your mix!

6. Not Staying Focused

Mixing is a race against time. The more time you spend listening to a mix, the more attached you become to the way it sounds. Give it enough time, and even the worst mix will start to sound pretty good.

And so, as the hours go by, it becomes harder and harder to make good mixing decisions. You’re constantly battling this loss of objectivity during the mixing process, whether you realize it or not.

The solution? Stop checking your text messages, playing Candy Crush, and mindlessly scrolling through your Facebook feed while mixing. Instead, covet every second of listening time. Because the more focused you can remain, the less time you have to spend listening to get the job done. And this means you can remain more objective along the way.

With more objectivity, you’ll make better mixing decisions, finish the job faster, and remain more flexible down the line if you need to make changes. This will be pretty helpful when the band sends you a page of mix notes the next day.

    Guilty of nearly every single one here. I will definitely be creating a sign that will be hung at the entrance of the control room stating the following… “Beyond this point, all distractions from the outside world will be set aside until the final product is satisfactory. This is a place where objective thinking and creative, on-the-fly decisions are made. PLEASE help keep the vibes flowing strong.”

    On a much more serious note, you guys have singlehandedly helped guide my perception of sound, perspective as a mixing engineer and overall knowledge level Sky rocket into the right direction.

    Matt Weiss, David Glenn and of course the writer of this very article Jason Moss (among the many other engineers involved here on The Pro Audio Files). Thank you for opening up to all of us following your lead in the industry and giving us a little peak into the mind set & approaches that have helped mold your careers. It is truly a gift I don’t take for granted.

      Your note made my day David! So glad I (along with the rest of The Pro Audio Files community) could be of service.

      We’re all in this together—the more we can share with each other, the better we all can be.

    I totally agree with David Cantu! You guys in theproaudiofiles really helped me so much and still are of course. Thanx a million and keep up the brilliant work!! I am forever gratefull!

    Bouncing a mix or master and calling it ‘final’. A good night’s sleep will give you a nice re-listen as long as you number them, don’t ever qualify them as ‘final’.

    I’m mixing the tracks of our band for our debut album. It’s both a challenge with great recordings and feedback from the other members. But: mixing different songs in one big direction is very difficult! These mistakes are the worst indeed!

  • Great article! I never put any limiting or compression on the master buss when mixing. Why would you even need to do that?

  • Gary

    Valuable advice Jason! I guess the solo button is one of my biggest enemies. I plan on working on that problem. Thank you very much!
