Reverb is like the icing on top of every mix cake. It adds depth and richness, makes performances sound more natural, and smooths out some of the rough edges in your tracks.
At times, reverb can even be used as a creative, tone shaping effect, rhythmic pulsation tool, and more. There are many ways to use reverb that aren’t always obvious.
So, in this guide, we look at the best free reverb VST plugins that will add much-needed glue to your mixes.
Valhalla Super Massive by Valhalla
Valhalla Super Massive may not need much of an introduction. Some even consider it the best free reverb / delay VST plugin available, and if you’ve been using reverbs for a while, you may even agree.
If that doesn’t make you want to run out and download it right away, I’m not sure whether this description will. That said, this is a guide, and we intend to offer as much useful information as possible.
So, Valhalla Super Massive (or Valhalla Supermassive / ValhallaSupermassive, depending on who you ask), offers up 14 delightful reverb and delay modes that cover all the bases, from fast attack and short decay echoes to slow attack, long decay, and high echo density variations. And they all have fun names, like Gemini, too.
Valhalla Super Massive comes with controls for mix and width, delay and warp, feedback and density, mod and depth, EQ and low, but the 14 modes really set the foundation for the type of effect you’re going to get.
Valhalla plugins are well loved among a variety of producers, including well-respected pros. And while Super Massive might be free, that doesn’t mean it’s of lesser quality. The reverbs are quite natural and deep sounding, even compared to some paid plugins out there.
Chances are you won’t regret adding this VST to your arsenal.
MCharmVerb by Melda Production
Melda Production’s range of free plugins have equipped countless producers with the essential tools they need for editing, mixing, and mastering. MCharmVerb is just one such tool.
This go-to favorite is an algorithmic reverb based on the MTurboReverb engine. It comes with all the great features Melda Production plugins are known for – advanced, resizable GUI, MIDI controllers and MIDI learn, global preset management, online preset exchange, visualization engine, automatic gain compensation (AGC), safety limiter, multiparameters, and much more.
MCharmVerb, for the most part is a clear, transparent reverb you can use on all types of tracks. It’s easy to configure and it sounds great.
This is an amazing reverb VST overall, and it’s beyond cool that it’s free. But I’m not sure that it compares to Valhalla Super Massive, even though this may not even be a fair comparison.
But hey, it all depends on what you’re using the reverb for, and there are no rules against adding multiple reverbs to your toolkit. Not to mention – there are a ton of great reverb VSTs on this list with different types of sounds and features.

TAL-Reverb-4 by TAL Software
For Linux, Windows, and Mac, Tal Software’s TAL-Reverb-4 is a quality digital plate reverb with a vintage 80s feel.
With a colorful, high resolution, attractive design, and simple controls, TAL-Reverb-4 works on just about any source material. And there really isn’t much to it! That makes it a great choice for beginners too.
Personally, I think TAL-Reverb-4 has a great sound to it, especially when used in moderation. Of course, there’s nothing wrong with long decays if that’s what you’re going for, and this reverb can keep those reverberations going for a good long while if that’s what you need.
From subtler doubling / chorusing style effects to huge, long decay reverbs with modulation, you can dial in some very effective and great sounding tones with TAL-Reverb-4, at least within a relatively limited range.

Convology XT by Wave Arts
Wave Arts collaborated with Impulse Record to create Convology XT, a free convolution reverb. This plugin comes with over 70 impulse responses, a variety of presets, and various IR modification features. Impulse Record even has additional IR libraries for those who want them.
This plugin, not surprisingly, is focused on vintage reverb effects. Convology XT features four-channel true stereo impulse responses, with pro DSP units, plates, and springs.
With an easy to user interface, you can easily cycle through presets and audition them on the fly.
There are a variety of classic sounds built into Convology XT, and they’re all configurable. Some even say it’s the best convolution reverb plugin available. You can be the judge of that, but either way we think it’s a cool plugin with cool options, and you should check it out.

Ambience by Smartelectronix
Developer Smartelectronix’ claims Ambience is a free reverb on par with the best commercial level reverb VST plugins available.
It comes with parameters that give you control over presets, dry, wet, time, size, pre-delay, width, quality, variation (creates a new variant of the same room), damping section, EQ section, gating section, hold, and diffusion.
Now, we can’t necessarily attest to the idea that Ambience is just as good as some of the top reverbs out there. What we can say, though, is that it does serve up some nice sounds, and they are quite configurable.
Check out the video to hear how Ambience sounds on a piano.

OrilRiver by Denis Tihanov
Denis Tihanov’s OrilRiver tends to make it into many best-of reverb VST plugins lists. It could be because of the attention and love it has received over the years, and some even say it’s the best free reverb VST available.
This is an algorithmic stereo reverb effect that lets you tap into everything from small room to great hall sounds depending on the effect you want to achieve.
OrilRiver will give you 12 variations of early reflections, five reverb tail variations, and three-band equalizer for the wet signal. All this is wrapped in an attractive UI package, with multiple themes.
This VST can produce some rich, transparent reverb effect perfect for a variety of applications.
OrilRiver is no longer being updated, but it’s still worth a mention.

Protoverb by u-he
u-he continually impresses us with their synths, including their free ones. So, we suspect their reverbs – even if free – are quite capable as well. Though, in this case, “proto” seems to represent “prototype,” for reasons we’ll get into.
Its graphical user interface has kind of a 50s vibe to it, which might have you thinking it’s a vintage verb. But the developer says it’s a reverb based on the concept of a room simulator, and it’s an experimental plugin intended for research purposes.
Interestingly, it basically does the opposite of what most algorithmic reverbs do. Protoverb builds up as many room resonances as possible while modeling the body of air in the room. This results in a natural sounding verb, they say.
Taking advantage of multiple parallel, serial, and networked delays, Protoverb gives you somewhat random results, so dialing in your tone might be more a matter of luck than anything else.
The text box in the interface comes with an alphanumeric string with two random parts. The first is for the network structure, spatial layout, distribution of delay taps, and so on, while and the second sets various parameters like delay length. This text can be inputted or randomized.
The text box doesn’t interfere with the decay, dry, and wet knobs, but more so sets you up with new presets every time you randomize it. No wonder u-he call it “experimental.”
Overall, this is an interesting reverb, just as you would expect. The presets give you a great starting point, and they are well suited to their intended purpose. Some producers even found it especially useful for sound design.
Voxengo OldSkoolVerb Plus by Voxengo
Smooth, rich, and deep. Voxengo’s OldSkoolVerb Plus became an instant favorite of mine as I started using it in my projects. I don’t know whether every producer will find the same utility I found in it, but I couldn’t possibly end this guide without drawing your attention to it.
This algorithmic reverb offers plate, room, hall, and stereo reverberation for use with drums, guitars, vocals, pianos, synth pads, and just about anything you can think of.
The interface features parameters for the character module (pre-delay, space, time, and width), damping module (damp lo, damp hi), EQ module (EQ lo, EQ mid, EQ hi), and out module (reverb, dry). The latest version (Plus), though, comes with control over the spatial image of the effect too.
I rather enjoy the built-in presets, as they offer good jumping off points for dialing in your perfect reverb effect sounds. Out of the box, the presets are usually quite exaggerated, and need to be dialed back for optimal use. But it is nice to be able to hear what the effect sounds like before you scale it back.
Voxengo OldSkoolVerb Plus is available for Windows and Mac.
Dragonfly Reverb by Michael Willis
Michael Willis’ Dragonfly Reverb has kind of a compelling name, but it’s equally mysterious since the website offers minimal documentation (though you can get Dragonfly Reverb T-shirts!).
What we do know is that this isn’t just one plugin. It’s a bundle of plugins – Dragonfly Plate, Dragonfly Room, Dragonfly Hall, and Dragonfly Early Reflections. The names should be self-explanatory to anyone who understands reverb, but it is kind of cool that there are multiple effects in one bundle.
These reverb effects are quite configurable. I do not find them to be the most organic or transparent sounding reverbs available, but sometimes that’s exactly what you need. Have a listen for yourself in the video below.
The Dragonfly Reverb bundle is available for Linux, Windows, and Mac.
Verberate Basic 2 by Acon Digital
Based on Verberate 2, Verberate Basic 2 comes with high quality presets, including plate, room, hall, and lush hall effects.
Acon Digital keeps it simple with a very straightforward and nicely designed interface. Simply choose from the four reverb types and dial in the reverb mix to get a deep, full, natural sounding reverb (also watch the video to see it in action). It’s as simple as that.
Verberate Basic 2 is Windows and Mac compatible.

epicVerb by Variety Of Sound
Variety Of Sound’s epicVerb sure has a cool rackmount gear style interface. Someone obviously knew what they were doing when they created the graphics for it.
epicVerb was designed as a tight small room and ambience effect that perfectly complements drum and vocal tracks.
It is highly versatile, offering a variety of sounds, be it smooth and transparent or concrete and edgy.
epicVerb comes with two reverberation modes, six stereo early reflection models, reverb time handling for high and low frequencies, EQ section, as well as low-pass and high-pass filtering.
Some reviewers called it the best free reverb out there.
As with some of the other plugins on this list, though, the demos for epicVerb aren’t entirely reliable. To get a better sense of how it sounds with your own projects, the best idea would be to download and experiment with it yourself.

Sabrina Reverb by We Love Walter
Right off the bat, you can tell that We Love Walter’s Sabrina Reverb is a simplistic effect. There are only controls for mix, diffusion size, diffusion amount, recycle, LFO amplitude, and LFO speed. To be fair, that might be more than some of the most minimal reverb effects feature.
Sabrina Reverb was designed to offer a deep, rich, and smooth reverb effect. While it is clearly simple, it is surprisingly versatile too.
It might be a little lesser known, but evidently, some electronic producers thought that Sabrina may well be one of the best reverbs for ambient music. You can also check it out in the video below.
Sabrina Reverb is available for Windows.

Teufelsberg Reverb by Balance Mastering
Balance Mastering’s Teufelsberg Reverb is your essential “cold war surveillance” reverb.
This plugin features reverbs appropriately captured at the Berlin surveillance tower, six IR sounds, fast, zero-latency convolution, as well as A/B compare and preset saving functions.
This reverb can go from subtle and smooth to hollow and shadowy with the turn of a dial. Really interesting stuff. It’s not sophisticated by any means, but it’s one of the few plugins that can take your echoes way over the top.
Aside from that, there isn’t much to it! Teufelsberg Reverb is free and open source, and it’s compatible with Linux, Windows, and Mac.

KR-Reverb FS by KResearch
KResearch’s KR-Reverb FS is a Linux, Windows, and Mac compatible reverb effect. Based on KResearch’s premium product, KR-Space, this easy-to-use effect produces a warm reverberation you can use on just about anything.
It is quite basic, and it doesn’t feature too many parameters, but you can adjust early reflection size, late reflection size, diffusion, decay, early / late reflections mix, and dry / wet to dial in your ideal tones.
There isn’t too much else to this one. It’s a simple, configurable reverb with a decent sound.

MuVerb by MuTools
MuTools’ MuVerb is available as a free, standalone reverb VST plugin.
It’s quite simplistic. You’ve got control over decay, damping, dry / wet, left pre-delay, right pre-delay, frequency, Q factor, turbulence amp, and turbulence speed.
The reverb is decent enough, but the demos out there are a little unreliable. They don’t give you a very good idea of what MuVerb is supposed to sound like. To get a true feel for the reverb, you’ll probably want to give it a try yourself and see how you like it.
Mverb 2020 by SocaLabs
SocaLabs’ Mverb 2020 was based on Martin Eastwood Audio’s Mverb and is essentially a 64-bit update thereof. It features a simple interface with parameters for mix, pre, EI/Mx, size, density, band, decay, damp, and gain.
Depending on how you dial in your tones, you can almost produce a slap-back echo type effect with Mverb 2020, which is pretty cool.
Overall, it’s a nice quality reverb.
Wollo Spacer by Erik Wollo
Erik Wollo’s Wollo Spacer features two reverbs paralleled, stereo phaser, delay, on / off button, volume, direct level gain, and a preset manager. In that sense, I suppose you could even call it a multi-effects plugin.
The delay section features parameters for D1 L, FB, GN, Pan, Mix, D2 R, FB, GN, and pan. The phaser module has controls for Fmin, Fmax, rate, feedback, StDif, sync, mix, and volume. Finally, the reverb section has controls for volume, envelope, size, wide, damp, and mix (for each of the two reverbs).
While the demos are a little unreliable, we can tell that you can achieve a variety of interesting effects with this VST (including rhythmic pulses), and the fact that modulation is built in is probably going to appeal to certain producers as well.

Lisc-Verb by Saltline
Saltline’s Lisc-Verb is a free reverb and delay effect.
It comes with dry signal routing, direct to output (effect mix / gain), state variable filter (low pass, high pass, band pass, band reject, frequency cut-off, resonance), dry signal to effect (direct to effect and state variable filter effect), and reverb (normal, free and gated modes, gate amount, size, width and damp).
It also includes reverb / delay mix, delay (rate – free / sync, rate adjust – free/sync, delay offset, feedback), reverb / delay state variable filter (low pass, high pass, band pass, band reject, frequency cut-off, resonance), output (effect mix – wet / dry), and gain.
Lisc-Verb is a cool reverb effect all on its own. But it can even be utilized for tone shaping your inputs. This quality is probably what has attracted many producers to this VST.

DRX8R by 7air Media
Made primarily for drums, 7air Media’s DRX8R offers reverb and compression in a convenient package. And it features a cool looking analog style VU meter. Overall, though, the design is kind of low-res.
While it has received a decent rating, if you want to hear exactly how it sounds, you’ll want to download and install it on your machine. Video demos won’t give you much of an idea.

Room Reverb by ElephantDSP.com
Room Reverb is a mono / stereo algorithm reverb. It comes with a variety of small and large room presets, undo / redo, A/B comparison, separate level controls for all reverb parts, stereo width control, resizable user interface, and built-in explanation for all plugin parameters.
For the most part, we find Room Reverb offers a relatively subtle, dry, natural effect.
Spacelifter 3 by Fananteampro
Spacelifter 3 is a modular space effect. It comes with a frequency range module (wet EQ), LFO module (with five motion engines), ping pong module (panning effect), and side-chaining module (ducking effect).
At first brush, this plugin seems a little obscure. Everything from the product description to the user interface are just a little different.
But when you start playing with it, you begin to see what all the fuss is about. This “spacer” reverb, in addition to echo, can be used as a creative rhythmic pulse type effect, among other things.
The video below shows off some of Spacelifter 3’s capabilities.
FogPad by igorski
igorski’s FogPad is a multichannel reverb effect.
Where most reverbs attempt to recreate an array of acoustic spaces, FogPad plunges you into a world of murky nebula and frozen thoughts trapped in memories. Exactly what that means, we don’t know, but essentially, it means that reflections can be bent and transformed with the fully automatable parameters.
Play with the mist, hue, murk, bother, and commingle module parameters to dial in the perfect amount of mist. It’s a little unusual, sure, but the best reverbs aren’t always the most conventional ones, and you never know when this might come in handy.
FogPad is an excellent selection for experimental purposes, and for those times when you want your reverb / delay to occasionally recall aspects of the performance that happened earlier in the performance.
FogPad is compatible with Windows and Mac.
How To Use Reverb In Your Projects
Let’s face it – reverb goes on just about every track!
The temptation, then, might be to apply a reverb effect to your mix / master and call it a day.
That is certainly the simplest of solutions, but it’s rarely the pathway to creating the best sounding mixes.
Obviously, there are many techniques, and I’m not here to tell you what’s right or wrong. But there are some things worth considering.
Some tracks sound better with less reverb – like bass or in-your-face distorted electric guitars.
Some tracks sound better with more reverb – synth sounds, for example, can take a lot of reverbs and still sound amazing. Background vocals are often complemented with heavier reverb, too, because it pushes them a little bit further in the background.
The point is to find ideal settings for each of your vocal and instrumental tracks. Most reverb plugins come with presets that give you a starting point for a variety of applications. So, that’s where presets come in especially handy.
Top Free Reverb VST Plugins, Final Thoughts
Reverb is an essential effect. To that end, I’m sure you’re elated to know that there are so many free reverb VST plugins out there.
Reverb is certainly one of those effects that’s subject to personal taste. So, be on the lookout for things you like because you just never know what you might be able to use and how it might end up becoming your trademark sound.
