Mastering Plugin Order: 7 Steps for a Clean Final Chain

Mastering plugin order matters less than most producers think, and more than most YouTube tutorials admit. There's a framework that works across genres, but there's no single template that beats understanding why each processor goes where it does.

We've run enough sessions to know that a rigid chain copied from a forum post will hold you back. But so will no structure at all.

What follows is the order we actually use, why we use it, and where the rules genuinely bend. We'll call out the specific points where swapping processors changes the outcome you can hear, not just the ones that look tidy on paper.

If your limiter is pushing more than 3dB of gain reduction, no amount of clever plugin ordering will fix your mix. We'll get to that too.

What Is a Mastering Chain and Why Does Order Matter?

A mastering chain is a linear series of processors on your master bus. Audio goes in one end and out the other. Each processor hears what the one before it did. That's the whole game.

Order matters because processors interact. Send a harsh 3kHz peak into a compressor before you've cut it, and the compressor hears that peak and reacts to it. The transient behaviour changes. The timing of compression changes. You've introduced a character that's harder to undo than it was to avoid.

Corrective moves belong upstream of creative ones. Linear corrections belong upstream of non-linear processors. That's the core principle, and it holds roughly 90% of the time.

The other 10% is where taste lives.

What's the Correct Order for Mastering Plugins?

Here's the chain we'd build from scratch, with the reason each slot exists.

Slot 1: High-Pass Filter

Cut everything below 15Hz. Always. Infrasonic content is inaudible but it's burning headroom. A 24dB/octave high-pass at 15Hz in a linear-phase EQ like FabFilter Pro-Q 4 costs you nothing and buys back real ceiling for the limiter.

We put this first so nothing downstream is reacting to content no one will ever hear.

Slot 2: Corrective EQ

Fix problems here. Narrow cuts. Take out the 200Hz mud, the 3kHz harshness, the boomy low-mid buildup around 250Hz. Use minimum-phase mode for surgical cuts if you're not doing phase-critical work, or linear-phase if the material is especially dense.

This is subtractive work. You're removing what's wrong, not adding what you wish was there.

Slot 3: Compression

Compress after corrective EQ. Here's why: if a harsh 4kHz frequency goes into the compressor before you've addressed it, the compressor clamps down harder during bright transients. That changes the feel of the whole track. You've shaped the dynamics around a problem you should have removed first.

For most mastering work, aim for 1 to 2dB of gain reduction. Bus compressors like the UAD SSL G-Bus Compressor or the Opto mode inside iZotope Ozone 11 work well here. The classic glue setting on the SSL is 4:1, attack at 30ms, release at 0.1ms, threshold around -15dBu, and gain reduction sitting between 1 and 2dB.

VCA compressors react fast and sit tight. Opto compressors breathe more naturally. Knowing which to reach for is more valuable than knowing what slot to put compression in.

Slot 4: Stereo Imaging

Widen or tighten after compression. The compressor has settled the dynamics. Now you can make informed decisions about stereo width without chasing a moving target.

Don't widen below 200Hz. Phase issues in the low end will destroy your master on mono systems. Keep the mid-side balance focused on the 2kHz to 10kHz range if you're looking to open up the image.

Slot 5: Sweetening EQ

This is additive work. Small shelf boosts. Air at 16kHz. A gentle low-shelf lift below 80Hz. The stuff that feels good rather than corrects bad.

This slot is where the EQ/compression order debate actually lives. Some engineers put sweetening EQ before compression so the compressor "hears" the finished tone. Others put it after so compression doesn't react to the boost. Both are valid. We prefer sweetening after compression, because we'd rather compress the corrected signal and then beautify it.

Slot 6: Saturation or Exciter

Tape saturation, harmonic excitation, subtle drive. This adds even-order harmonics and gives the master presence without turning up the volume. Tools like the Waves Abbey Road TG Mastering Chain include saturation stages built directly into the signal flow.

Keep this subtle. We're talking 1 to 3% drive settings. If you can clearly hear the saturation, you've gone too far.

Slot 7: Limiter

Always last. Non-negotiable. A brick wall limiter is your final protection against overs, and it sets your output ceiling.

Target 1dB of gain reduction for transparent loudness. Push to 3dB if the track demands it. Go beyond 3dB and you'll hear it, especially on transient material like acoustic drums or plucked strings.

If your limiter is working harder than 3dB, the mix needs attention, not more creative plugin ordering.

Does the EQ-Before-Compression Rule Actually Hold Up?

It does, but not as rigidly as most articles suggest.

Subtractive EQ before compression is close to universal. You don't want a compressor reacting to frequencies you plan to remove anyway. Harsh frequencies that get compressed are amplified along with everything else during gain reduction recovery. You've made the problem louder and harder to control.

Additive EQ before compression is a different question. We ran the same pop master through iZotope Ozone 11 twice. First: 2dB shelf boost at 12kHz before the compressor. Second: same boost after the compressor. The version with EQ before compression sounded airier but the transients felt slightly dulled. The version with EQ after compression felt cleaner and the high-end shelf sat more forward in the mix without fighting the compressor's attack stage.

That's a real difference, and it confirms the preference for post-compression sweetening on bright material. On warmer, slower material like jazz or acoustic folk, pre-compression EQ boosting can actually work in your favour because the compressor's reaction becomes part of the character.

Genre changes the answer. Know your material.

Where Do Genre Differences Change the Chain?

This is the gap most mastering guides leave open. Here's how we'd adjust the standard chain for three common genres.

Electronic and Club Music

The kick needs to punch through every playback system. We'd add a second, focused compressor on a mid-side split before the limiter: compress the mid more aggressively (2 to 3dB), leave the sides lighter. This keeps the low end punchy and the stereo image wide simultaneously.

Saturation on this format is useful but risky. Keep harmonic excitation above 2kHz only. Below that, saturation on a club track adds intermodulation that muddies the kick-bass relationship.

Rock and Metal

Low-mid buildup around 200 to 350Hz is the enemy. We'd prioritise a surgical notch in the corrective EQ slot, sometimes two notches. Compression settings tighten to 4:1 with a faster release to keep the aggression intact.

The limiter will work harder on this material. 2 to 3dB of gain reduction is normal. If you hate the pumping, try a clipper before the limiter and let the limiter touch 1dB maximum.

Jazz, Classical, and Acoustic

Keep your hands off it. Seriously. Light corrective EQ, 1dB of gentle compression maximum, no saturation, and a transparent limiter set to -0.3dBFS ceiling. The job here is to not break what already sounds good.

FabFilter's Pro-L 2 in "Transparent" mode is our pick for acoustic material. It's the most honest limiter we've tested on dynamic range-sensitive content.

What Are the Most Common Mastering Chain Mistakes?

Putting the Limiter Anywhere But Last

We've seen this. It's usually called "parallel limiting" by people who've misunderstood what that means. The limiter must be last. No exceptions worth discussing.

Skipping Gain Staging

Every plugin in your chain has a sweet spot. If your compressor input is hitting -3dBFS and your EQ expects -18dBFS, you're clipping at the input stage of a plugin and wondering why the chain sounds harsh. Check gain structure between every processor.

We use TB Pro Audio's MvMeter2 between plugins to confirm levels. Free, accurate, and it runs on almost no CPU.

Over-Processing Because It Looks Professional

Eight plugins in the chain does not mean eight improvements. Every plugin you add adds latency, potential phase shift, and more variables to troubleshoot. We've done satisfying masters with three plugins: corrective EQ, light compression, and a limiter. That's the whole chain. If the mix is good, that's enough.

Ignoring the Limiter Overload Signal

If your limiter is clamping more than 3dB, you have a mix problem. The three most common causes are: a kick drum that's too loud relative to the mix, a reverb tail that's pushing the ceiling on every hit, or uncontrolled low-end energy below 60Hz that's eating headroom. Fix those in the mix. The mastering chain can't rescue them.

Which Tools Actually Help You Learn Plugin Order?

Beyond the processors themselves, a few resources are worth keeping open while you work.

Summary

The mastering plugin order that works: high-pass filter, corrective EQ, compression, stereo imaging, sweetening EQ, saturation, limiter. The limiter is always last. Subtractive EQ belongs before compression. Additive EQ can go before or after, but after compression usually sounds cleaner on modern material.

Genre changes the details. Your mix determines whether the chain works at all. If the limiter is clamping more than 3dB, fix the mix. If you're using eight plugins and something sounds annoying, remove three and start again. Fewer processors, each set correctly, beats a packed chain every time.
