The Best Free Plugins for Mixing (That I'd Actually Use on a Paid Mix)
Let me save you a credit card charge: you don’t need to spend a dollar on plugins to get a professional-sounding mix. The best free plugins for mixing available right now are genuinely good enough that I’d put several of them on a paid client mix without thinking twice — and a few of them I do.
Here’s the thing though. “Free” is also how beginners end up with 200 plugins and zero finished songs. So this isn’t a dump of every free plugin on the internet. It’s a short list, organized by job, of the ones that actually earn a slot — plus an honest take on when your stock plugins already have you covered.
Real Talk First: Your Stock Plugins Are Better Than You Think
Before you download anything, hear me out. Every major DAW — Logic, FL Studio, Ableton, even GarageBand — ships with an EQ, a compressor, a reverb, and a delay that are fully capable of a professional mix. Muddy mixes don’t come from stock plugins. They come from decisions — that’s usually why a mix sounds muddy, not because the EQ wasn’t expensive enough.
A free third-party plugin is worth installing when it does something your stock tools don’t do, or shows you something they don’t show you. That’s the filter for everything on this list. If a plugin just duplicates your DAW’s EQ with a different skin, skip it.
Okay. With that filter in place, here’s what actually makes the cut.
Best Free EQ: TDR Nova
TDR Nova is a parametric EQ that’s also a dynamic EQ — meaning each band can react to the audio instead of cutting the same amount all the time. That’s the feature that makes it worth installing next to your stock EQ.
Why that matters in practice: say your vocal only gets harsh on the loud phrases. A normal EQ cut at 3–5 kHz dulls the whole take. A dynamic band in Nova only cuts when the harshness actually shows up, and leaves the rest alone. Same trick works on a boomy 808 that only jumps out on certain notes.
Start here: use your stock EQ for basic shaping, and reach for Nova when a problem comes and goes with the performance. If you’re still getting comfortable with EQ moves in general, my guide on how to EQ vocals covers the actual frequencies to look at.
Best Free Compressor: Kotelnikov (Tokyo Dawn Records)
Same developer as Nova, same story: pro-level tool, zero dollars. Kotelnikov is a clean, transparent compressor that’s honestly hard to make sound bad — which is exactly what you want while you’re learning.
Compression is the concept beginners fight with the longest, and a big part of that is fighting a compressor with a confusing interface at the same time. Kotelnikov shows you its gain reduction clearly and responds predictably. Set the threshold so you’re getting 2–4 dB of gain reduction on the loud parts, leave the ratio around 2:1, and listen to what happens. That’s a real compression education, free.
If the settings themselves still feel like alphabet soup, the beginner’s guide to compression breaks down every knob in plain English.
Best Free Saturation: Softube Saturation Knob
One knob. That’s the whole plugin. Turn it up, things get warmer and more aggressive; the switch underneath decides whether it hits the lows, mids, or highs hardest.
This is the plugin I recommend when someone says their mix sounds “thin” or “digital.” A little saturation on an 808, a vocal bus, or drums adds harmonics — extra frequency content that makes a sound feel bigger and helps it cut through on small speakers. Expensive analog emulations do this with more options. The Saturation Knob does it with one, and for learning what saturation even sounds like, fewer options is a feature.
Start here: put it on your 808 or bass, keep it subtle, and A/B with the bypass button. If you can obviously hear it working, you’ve probably gone too far.
Best Free Reverb: Valhalla Supermassive
Valhalla’s paid reverbs are on records you listen to every day, and Supermassive is their free one — huge, lush, gorgeous spaces and delays. It’s not the reverb for a tight, subtle vocal room sound; your stock plate can do that. It’s the reverb for when you want a hook vocal or a pad to sound massive.
That distinction matters: use stock reverb for realism, Supermassive for drama. And either way, reverb is the fastest way to drown a vocal if you set it up wrong — send levels and pre-delay do more than the reverb brand does. I walk through the whole setup in how to use reverb on vocals.
Best Free Metering: Voxengo SPAN + Youlean Loudness Meter
Neither of these touches your sound. Both make you better at mixing, which is why they’re on the list.
SPAN is a spectrum analyzer — it shows you where the energy in your mix actually lives across the frequency range. Throw it on your master bus and compare your mix to a professional track in the same genre. When your low end is a wall and theirs is controlled, you’ll see the difference before you’ve trained your ears to hear it.
Youlean Loudness Meter tells you how loud your track actually is in LUFS — the measurement streaming platforms use. This one answer alone (“why does my song sound quieter than everyone else’s on Spotify?”) is worth the install.
Neither replaces your ears. Both speed up the process of training them.
Start here: load SPAN on your master, pull up a reference track you love, and bounce between the two while you mix. Then check Youlean at the end — if your master is hitting around -14 LUFS integrated, you’re in the streaming sweet spot and you can stop chasing loudness.
Worth a Mention: OTT (Xfer Records)
You’ll hear about OTT constantly, so let’s address it. It’s a free multiband compressor that squashes everything, hard, in a very recognizable way — it’s all over modern electronic music, and it makes almost anything sound instantly loud and bright.
That’s also the trap. OTT is a strong flavor, not a foundation. If you use it, dial the Depth way down from 100% — try 15–30% — and know that it’s a sound-design choice, not a fix for a weak mix. It pairs naturally with the pumping-style tricks in the sidechain compression tutorial if that’s the lane you produce in.
A Quick Word on Installing These Without Breaking Your Session
Two practical things nobody mentions in plugin roundups, and both will save you a headache.
Download only from the developer’s own site. Every plugin on this list is free directly from TDR, Softube, Valhalla DSP, Voxengo, Youlean, and Xfer. Third-party “free VST pack” sites bundle old versions, installers full of junk, and occasionally worse. The real thing is free anyway — there’s no reason to get it anywhere else.
Install one, use it for a week, then install the next. I’m serious about this. If you load all six into a session tonight, you’ll skim each one for two minutes and learn none of them. Put Kotelnikov on your vocal bus for a week of sessions and you’ll actually know what it does by Friday. Slow is fast here.
And if a plugin doesn’t show up in your DAW after installing, it’s almost always a format or scan issue — make sure you grabbed the right format for your DAW (AU for Logic, VST3 for most everything else) and rescan your plugins in preferences before assuming it’s broken.
The Free Plugin Trap (Read This Before You Download 50 More)
Here’s the part nobody tells you: the biggest cost of free plugins isn’t money, it’s attention. Every new plugin is a new interface to learn, a new “maybe this will fix my mix” rabbit hole, and one more decision between you and finishing the song.
The producers whose mixes improve fastest aren’t the ones with the biggest folders. They’re the ones who pick a small set of tools and learn them deeply — which is the same reason collecting plugins made my list of common mixing mistakes.
So here’s the whole starter kit, and I mean the whole thing: your stock plugins, plus Nova, Kotelnikov, Saturation Knob, Supermassive, SPAN, and Youlean. Six downloads. Everything on this list runs on macOS and Windows, and none of it costs a cent. Learn those and you’ll outgrow “free vs. paid” as a question — because you’ll know exactly what a paid plugin would need to do to earn its price.

Plugins are the easy part — knowing what to do with them is the actual skill. The Bedroom Producer’s Blueprint is my $17 eBook that covers the whole picture: recording clean vocals at home, mixing workflow from first fader to final bounce, the beginner mistakes that keep mixes sounding amateur, and budget gear and plugin recommendations that go deeper than this post. It’s everything I wish someone had handed me when I was turning knobs and hoping for the best.
