What Are Stems in Music? A Metal Producer’s Guide

Nail The Mix Staff

You’ve finished tracking. Your DAW session is a beast—16 tracks of drums, quad-tracked rhythm guitars tuned to Drop F, layers of synths, and a dozen vocal tracks. The mix is dense, powerful, and ridiculously complex. Now what?

You’ve probably heard the term “stems” thrown around, but what are they, really? And more importantly, how can they save your ass when dealing with the beautiful chaos of a modern metal mix?

In short, stems are stereo recordings of major instrument groups, bounced from your final mix session. Think of them as sub-mixes: one stereo file for all your drums, one for all your guitars, one for vocals, and so on.

They are the key to unlocking next-level control, collaboration, and the hyper-polished sound that today’s metal scene demands. Let’s dig in.

Stems vs. Multitracks: The Key Difference for Metal Mixes

First, let's clear up a common point of confusion. Stems are not the same as multitracks.

  • Multitracks are the raw, individual audio files from your recording session. We’re talking Kick In, Kick Out, Snare Top, Snare Bottom, DI Guitar 1, DI Guitar 2, Lead Vocal Comp, BG Vox 1, etc. They are the individual ingredients.
  • Stems are the finished dishes, grouped together. For example, a single “Drum Stem” is a stereo file containing your fully mixed drums—all the individual mics, samples from Get Good Drums or Superior Drummer 3, EQ, compression, and reverb, all blended together exactly how you want them.

When you join Nail The Mix, you get the multitracks from bands like Gojira and Periphery. This lets you see the raw DNA of a professional production and build your mix from the ground up. But in many professional workflows—like remixing, live playback, or stem mastering—you’ll be the one creating or receiving stems.

Why Stems Are Essential for Modern Metal Production

The standards for metal production are higher than ever. That local band demo from 2003 with dodgy production wouldn't fly today. The modern metal audience expects every release to sound polished, massive, and perfect. Stems are a massive part of achieving that.

Taming Low-End Chaos and High Track Counts

Modern metal is defined by its density. With 8-string guitars from makers like Kiesel or Ormsby fighting for space with 5-string basses and sub-drops, the low end can turn into a muddy nightmare.

This is where stems become your best friend. By creating a "Guitar Stem" and a "Bass Stem," you can process these groups as a whole. You can slap a multiband compressor like the FabFilter Pro-MB across your guitar stem to control palm-mute buildup around 100-200Hz without affecting the top-end clarity. It allows you to manage the relationship between huge instrument groups instead of getting lost tweaking 30 individual tracks.

The Secret to Polished, Punchy Drum Sounds

Go listen to a modern metal record from a band like Spiritbox or Architects. The drums are inhumanly tight and punchy. That sound is a combination of killer playing, detailed editing, and heavy sample replacement/blending.

A final "Drum Stem" in a modern metal project often contains:

  • The fully edited and processed acoustic drum mics.
  • Blended samples (like a Slate snare or a GGD kick) to add punch and consistency.
  • Bus compression and saturation to "glue" it all together into one cohesive instrument.

By printing this to a stem, you lock in that perfect drum sound. It simplifies your final mix and ensures your drums hit with maximum impact at all times.

Fueling Collaborations, Remixes, and Live Shows

Modern metal is post-genre. Bands like Falling in Reverse and Bring Me The Horizon pull from hip-hop, pop, and electronic music. Spiritbox did a Megan Thee Stallion remix. This cross-pollination is awesome, but it presents a technical challenge: how do you send your track to a producer who works in a different genre?

You send them stems.

An electronic producer doesn't need your 24 individual drum tracks. They need one perfectly mixed "Drum Stem" to chop up and process. Stems are the universal language of collaboration. They're also critical for building live shows. The synth layers, backing vocals, and sound effects you hear at a show are often played back as stems, guaranteeing sonic consistency every night.

How to Create and Use Stems in Your DAW

Alright, theory's over. Let's get practical. Creating stems is basically just a specialized way of exporting your mix.

H3: Creating a Crushing Guitar Stem

Let's say you've quad-tracked your rhythm guitars using a killer Neural DSP Archetype plugin.

  1. Route to a Bus: In your DAW (Pro Tools, Reaper, Logic, etc.), route all four guitar tracks to a single stereo auxiliary track or bus. Let's call it "GTR BUS."
  2. Apply Bus Processing: This is where the magic happens. On your GTR BUS, you can add processing that affects all guitars at once. A classic move is to use an SSL-style bus compressor (like the one from Waves or UAD) with a slow attack and fast release to add punch and glue. Maybe you add a subtle EQ to carve out space for the vocals.
  3. Print the Stem: Solo the GTR BUS. Now, export or "bounce" the output of this bus as a new stereo WAV file. Label it "Rhythm Guitars – Stem." Done. You now have a single file representing your entire rhythm guitar sound.

H4: Watch Out for Time-Based Effects (Wet vs. Dry Stems)

Here's a pro tip: be careful with effects like reverb and delay. Do you want them baked into your stem?

  • Wet Stems: These include all effects. A "wet" vocal stem will have the reverb and delay printed into the audio. This is simpler and locks in your sound.
  • Dry Stems: These are printed without time-based effects. You would then create separate stems just for your effects returns (e.g., "Vocal Reverb – Stem," "Snare Reverb – Stem").

Creating dry stems gives a mix or mastering engineer way more flexibility. If you're collaborating, sending dry stems plus effects stems is standard practice.

H4: The Final Check: Are Your Stems Phase-Coherent?

When you export your stems, make sure they all start at the exact same point (bar 1, beat 1) and that when you import them all back into a new session and press play, they sound identical to your original mix. If something sounds weird, you might have a routing or plugin latency issue you need to fix before re-exporting.

From Stems to a World-Class Mix

Understanding and using stems is a huge step toward producing professional-sounding metal. It’s a workflow that helps you manage the complexity and density inherent to the genre.

But creating great stems requires one thing above all else: a great mix to begin with.

You need to know how to get that initial guitar tone right, how to make your drums punch through the wall of sound, and how to make your vocals cut. You need to master the fundamentals of EQ and compression to shape each element perfectly before it even hits a bus.

This is exactly what we teach at Nail The Mix. Instead of just theorizing, you get the actual multitracks from the biggest bands in metal and watch the world-class producers who mixed them explain every single decision they made. You’ll learn why they used a specific compressor on the drum bus or how they EQ'd the guitars to sit perfectly with the bass.
