What Is Mixing In Music? A Modern Metal Producer’s Guide

So, you’ve asked the big question: "What is mixing in music?"

If you’re here, you probably already know the textbook definition. It’s the process of taking all your individual recorded tracks—drums, bass, guitars, vocals—and blending them together using tools like level faders, panning, EQ, and compression.

But let’s be real. In the world of modern metal, that definition barely scratches the surface.

Mixing isn’t just a technical checklist. It’s not a magic "fix it" button that turns a bad recording into a banger. Mixing is the final, crucial step of the artistic process. It’s about taking something that’s already great and transforming it into a masterpiece that can compete with the professional records you love.

It’s about vision, enhancement, and making hundreds of small, deliberate decisions that add up to one massive, cohesive, and powerful sound.

The Real Answer: Mixing is Enhancement, Not Resurrection

Here’s the single most important concept you need to burn into your brain: Garbage in, garbage out.

The idea that you can take a sloppy performance with thin, fizzy guitar tones and "fix it in the mix" is the biggest myth in music production. All the processing power in the world, from the slickest plugins to the most expensive analog gear, can’t save a track that lacks power and precision at the source. A great mix starts with a great recording.

Think about bands like Gojira or Meshuggah. Their recordings sound monstrous even before a mixer touches a single fader. Why? Because they are insanely tight players with meticulously crafted tones. Joe Duplantier’s pick attack is a weapon. The synergy between Fredrik Thordendal and Mårten Hagström is a force of nature.

When you have source tones like that—a punchy kick drum recorded perfectly, a bass tone that has both low-end weight and midrange growl, and guitars that are tight and aggressive—the mixer’s job isn’t to perform CPR. Their job is to take that raw power from a 9/10 to a blistering 11/10.

The mix enhances what’s already there. It clarifies, it adds impact, and it creates a sense of space and depth. But the core energy? That comes from the performance.

The Core Components of a Modern Metal Mix

Okay, so you’ve got killer source tracks. Now what? The mixing process is where you organize the chaos into a polished, impactful final product. Here’s a breakdown of the key stages.

Balance: The Foundation of Everything

Before you even think about reaching for an EQ, you need to set a static mix. This is all about levels and panning.

• Levels: Start by pulling all your faders down. Bring up the most important elements first. In a dense metal mix, that’s often the kick and snare, then the vocals, then the bass, and then the rhythm guitars. Get a rough balance where everything can be heard and nothing is completely masking something else. This is your starting point.
• Panning: Create width and space. The standard for modern metal is to pan rhythm guitars hard left and hard right. This creates a massive stereo wall of sound and leaves the center open for the kick, snare, bass, and lead vocal—the core of your mix. Cymbals, toms, and ambient effects can then be panned to fill out the stereo field.

EQ: Carving Your Space in the Wall of Sound

In a genre as dense as metal, every instrument is fighting for its own spot in the frequency spectrum. EQ is your scalpel. It’s not just about making things sound "good" in solo; it’s about making them fit together in the context of the full mix.

• High-Pass and Low-Pass Filtering: This is your #1 move. High-pass filter (HPF) almost everything that isn’t kick or bass. Guitars don’t need much information below 80-100Hz; cutting it out cleans up mud and makes room for the low-end instruments. Likewise, low-pass filtering (LPF) guitars and cymbals can tame harsh "fizz" and create space for the vocal's air and clarity.
• Surgical Cuts: Got a nasty ringing frequency in your snare around 800Hz? Use a high-Q (narrow) cut with a plugin like the FabFilter Pro-Q 3 to notch it out without affecting the rest of the snare's body. Annoying "honk" in the guitars around 400Hz? Carve it out. This is about cleaning up problems.
• Broad Boosts: Want more "click" from your kick drum? Try a broad boost somewhere between 4-8kHz. Need more bite from your guitars? A gentle boost around 2.5kHz can help them cut through.

Compression: Taming Dynamics and Adding Punch

Compression is one of the most misunderstood tools in mixing. In metal, it serves two main purposes: controlling dynamics and shaping transients to add aggression.

• Controlling Performance: A great drummer is consistent, but not a machine. A compressor can even out the volume of snare hits, ensuring every hit lands with impact. For screaming vocals, heavy compression can keep the vocal pinned in place so it doesn’t get lost when the band kicks in. An 1176-style FET compressor (or a plugin like Slate Digital’s FG-Stress) is a go-to for this kind of aggressive, fast control.
• Adding Punch and Glue: Use a slower attack on a drum bus compressor to let the initial "crack" of the snare and "thwack" of the kick poke through before the compressor clamps down. On the mix bus, a VCA-style compressor like an SSL G-Comp model can add "glue," making all the individual elements feel like they’re part of one cohesive performance.

Compression is a secret weapon for powerful metal mixes. Learn the metal compression secrets that go beyond just making things loud.

Effects: Creating Depth and Vibe

Reverb and delay are what give your mix a sense of three-dimensional space and life.

• Don't Slap It On Everything: The key is to use effects on sends and returns, not directly on the track inserts. Create a few different effect buses: maybe a short plate reverb for the snare to give it some space, a longer hall reverb for guitar solos or clean sections to make them feel epic, and a stereo delay timed to the track for vocals.
• Pre-Delay is Your Friend: Want a vocal to sound big without getting washed out in reverb? Increase the pre-delay on your reverb plugin (like ValhallaVintageVerb). This creates a small gap between the dry vocal and the start of the reverb, preserving clarity while still adding a sense of space.
• Character Delays: A simple delay can be boring. Use a delay plugin with character, like the Soundtoys EchoBoy, and filter or saturate the repeats so they sit behind the main track instead of competing with it.

The Mixer as the Final Producer: Embracing the Modern Paradigm

In the old days, you had to save up a fortune to go into a huge studio with a producer and engineer. Your creative vision was filtered through them. Now, thanks to technology, the game has completely changed.

The barrier to entry for professional-sounding recording is lower than ever. With a powerful computer, a quality interface from a company like Focusrite or Audient, and a DAW like Reaper, you have more power at your fingertips than the biggest studios had 20 years ago.

This has created a new breed of artist—the producer-musician. Think of guys like Buster Odeholm (Humanity's Last Breath, Vildhjarta) or Devin Townsend. They write, perform, record, produce, and mix their own music. They are the ultimate gatekeepers of their own vision.

Embracing technology like the Kemper Profiling Amp to capture perfect amp tones, using Slate Trigger 2 to enhance inconsistent drum performances with powerful samples, or dialing in world-class guitar sounds with Neural DSP Archetype plugins means you can take control of your sound from start to finish.

Mixing is no longer just a service you hire someone for. For the modern metal musician, it’s the final stage of your own creative process. It’s the freedom to ensure the sound in your head is the sound that comes out of the speakers, with no compromises.

If you have the drive, there is literally nothing holding you back from creating professional, world-class metal in your own bedroom. The tools are there. The knowledge is out there. The only limit is your skill.
