Free Plugins For Mastering Vocals
Compressor VSTs
With vocal audio constantly wavering between high and low levels, a good compressor is nothing short of essential to the final mastering process. Check out some of these options to achieve a cohesive, condensed vocal sound.

OTT by Xfer Records
Pick it up here
With a simple yet sleek user interface, this plugin is approachable to engineers at all ends of the spectrum. The VST consists of 3 bands and is geared towards trap/electronic genres. OTT has the standard controls of any compressor: In/Out Gain, depth, and time without the clutter from any unnecessary bells and whistles. Each band is equipped with a modest visualizer, allowing you to see how your sound is being altered at different frequency ranges.
Although some producers may find the lack of options control-wise limiting, OTT is quick to get you to the sound you desire without wasting unnecessary time. Overall, the price is more than right, and OTT does an excellent job at evening out levels.
DC1A by Klanghelm
Pick it up here
If you’re looking for a simple compressor to give your vocals a bit more of an analog/classic feel, the Klanghelm DC1A is an excellent free plugin to start with. Its most notable feature is the 4 built-in presets with deep, relaxed, negative, and dual mono compression modes.
To add to its retro vibe, the VST has an embedded meter that looks like those on vintage rack mounts and is just as useful. The meter itself is easily understood and has a delineated red threshold so you can tell whether or not you’re clipping even with just a quick glance. The main focus of the plugin is the input and output, nothing else really besides the compression modes, making it a great option for beginners.
Moreover, Klanghelm produces a bulkier compressor VST entitled DC8C, so DC1A acts as a great trial run before investing in a paid plugin. For a seasoned engineer, this VST may be oversimplified, but those looking for efficiency or that classic mono sound, this is an excellent choice.
Equalizers (EQ) VSTs
When mastering a vocal, especially in pop/more current styles of music, producers commonly boost/cut out frequencies to help it stand out a bit more in the master mix. Here are a couple of free EQs that can fulfill all of your vocal mastering needs.

ReaEQ by Reaper
Pick it up here
In general, this EQ plugin is great for the entire production process, but it also has a couple of key features that lend themselves particularly towards vocal mastering. For example, the VST has a dial-in frequency feature that allows the user to enter precisely what frequency he/she would like to be emphasized or lowered. You are able to add an unlimited amount of bands to give absolute clarity to the vocal and add polish to its final master. The bandwidth can be widened or narrowed with a few mouse clicks, streamlining the process.
Moreover, each band has a separate bypass toggle, meaning that you can easily switch one on/off to compare a sound before/after processing. ReaEQ comes equipped with high and low pass filters, bands, much more. The central visualizer makes it easy to locate all of your bands. Although the plugin is not the most aesthetically pleasing, it certainly works well and has a lot of features that normally come with paid plugins.
It is a great plugin to download as a beginner, but able to translate into more mature mastering practices with its potentially highly specified input/output values. ReaEQ is a superb tool and comes as a part of the Rea PLugs bundle with many other useful VSTs.
Luftikus By Lkjb
Pick it up here
This EQ is super useful in achieving a retro sound, as it is a digitized version of an analog-style Equalizer. Luftikus is set up like a traditional rack mount and has 5 fixed-frequency EQ bands with corresponding knobs. This feature could be seen as limiting during the mastering process as you cannot type in specific frequencies in the same way that you can with previously mentioned ReaEQ.
However, if you’re mastering a vocal bus with multiple vocal tracks, having fixed bands can help simplify the process and give you a little boost without being excessive. In addition, the VST has an added “mastering” mode which removes superfluous features to get you in and out of mastering efficiently. Luftikus has a separate section dedicated to boosting the high-end frequencies and a couple of preset options between 2.5-40K Hz which is particularly useful during the vocal mastering process.
Outside of the presets, the high-end boost has a knob that can be altered for a more specific vocal top-end boost. The plugin has a “keep gain” button designed to make changes appear more subtle than drastic while EQing, ideal for mastering. The colorful interface makes it exciting to use and Luftikus proves to consistently create masters with a bit more of a vintage feel.
Nova-67P by Vladg/sound
Pick it up here
The Nova-67p is a hybrid between a compressor and an equalizer making it a fine resource for mastering. The plugin is centered around the main visualizer where you can view the waveforms and respective bands. It’s nice that you’re able to see the waveforms in realtime, especially since vocals are fickle and quick to change from one level to the next. Since it also acts as a compressor, there is a small level meter as well to prevent clipping the vocal tracks.
This unique combination makes the VST a one-stop-shop for vocal mastering. Although sidechaining is traditionally done within the mixing stage, it is certainly worth mentioning that this plugin has sidechain capabilities built-in, along with high and low pass filters. It comes with attack, release, and ratio knobs and a separate toggle for mastering. If you’re looking to EQ or compress exclusively, this plugin may not be the best choice as the two components are designed to be used together in the mastering process.
For those looking to do both processes anyway, this plugin certainly accelerates mastering and will give you a more put together sound as the EQ and compressor interact with one another beautifully.
Noise Gate VSTs
A less common but underrated gating possibility is centered around the vocals. Condenser and other common microphones, often pick up unneeded frequencies that can cloud your vocal clarity during the mastering process. In order to eliminate this, try out one of these free noise gate plugins and place it on a vocal track.

preFix by Variety of Sound
Pick it up here
Prefix acts as a couple of plugins built into one with EQ, sidechain, compression, and phasing built-in. Similarly to Nova-67P, the features are meant to be used with one another without external interference. The noise gate feature is notable as it has specified attack, release, hold, and pre-gate knobs allowing the user to hone in on which frequencies they’d like to be ducked.
Although this plugin is best used during the mixing process, it can be a great reference point during mastering since it includes so many of the tools needed to create a polished track. If someone was stuck on a vocal mix and wanted to be able to visualize a finished or mastered product, preFix could be placed on the corresponding vocal bus and quickly adjusted to give the user a vague idea of the polished product. Since there are so many controls and a lack of a frequency visualizer, this plugin can certainly be intimidating and time consuming for a beginner. However, a reference track on its own is extremely valuable, especially for something as nuanced as vocals, and when mastered, preFix is as effective as comparable costly VSTs.
GGate by GVST
Pick it up here
This plugin is as simple as it can get, but don’t let its minimal approach fool you- GGate is very powerful and is straightforward enough to be added to all kinds of vocals. The plugin consists of 3 knobs: The threshold, attack, and fade; Each pretty self-explanatory in their own right. GGate has a dry/wet meter so that the gated signal can be played alongside the unaltered signal. This opens the door to parallel processing for vocals, which can make a significant difference in the listener’s experience.
Moreover, the “fade” knob is suited to create subtle changes in the overall level of a vocal track. For those looking to give a more processed/clear sound to vocals, i.e those centered around commercial/pop genres, this plugin may prove to be insufficient. However, if you’re in a pinch or just need to eliminate a minute level of noise without being too obvious, you can’t beat the control offered by GGate.
Exciter VSTs
In the same way it is helpful to boost the preexisting high-end of vocals in order to bring the sound more upfront during mastering, exciters generate artificial/organic tones typically in the 3K range and above.

Thrillseeker XTC by Variety of Sound
Pick it up here
This exciter is based around analog-style retro sounds and combines a traditional exciter/saturator with a 3-band EQ. Each set EQ range has a separate knob and bypass button so that different frequency ranges can be enhanced independently. This is particularly useful in scenarios where one is utilizing a vocal bus and wants to master an overall sound without emphasizing unwanted tones/frequencies.
Best Free Compressor For Vocals
The plugin has a “Mojo” and Drive section, catered to leveling out the amplitudes of generated frequencies running parallel to the dry vocal. Moreover, the VST can be switched in between blue or black versions depending on how precise an engineer desires the finished master to be. Thrillseeker in this way lends itself to a variety of genres and applications. Although it is somewhat limited in being linked to retro or vintage type sounds, the VST is absolutely worth a try at no cost.
BuzVintageMaxi by Buzzroom
Best Free Vocal Vst Plugins
Buzzroom has created a true exciter plugin with BuzVintageMaxi. The VST is very minimal, with two main knobs: gain and ceiling for the threshold level of the audio signal. The plugin is known for adding thick, warm sounds to any track it is applied to. This can be especially useful for mastering female vocals, where sometimes the upper register can lose warmth/low-end frequencies when translated to an audio signal. It has two included processing modes, normal and deep, to cater to the depth of harmonics applied to the signal.
Although this plugin cannot be used to master an entire vocal tracks alone due to its lack of complexity, it certainly produces a warm vocal within a short amount of time. It’s definitely worth a try, even just train your ears on what a warm/fat vocal should sound like.
Modern Exciter by Antress
Pick it up here
Antress has a number of strong plugins free for download on their website. Modern Exciter has a user interface resembling a standard rack mount and is not overly muddled by too many controls. Harmonics can be added to low or high frequencies and adjusted with their respective knobs. This lends itself well to mastering vocals as different voices will have different areas in which they need more widening depending on the frequency of the dry audio signal. Modern Exciter includes a VU meter, which especially lends itself to mastering since it helps display the average level of the processed signal.
If you want more of a retro sound, this VST has a built-in analog preset. Moreover, the VST processes in stereo and has separate left and right channels appropriately. The plugin does not have a whole lot of controls which may seem to limit to some, but it notably separates the high and low ends to organically fill in vocal frequency gaps.
Quick Tips For Mastering Vocals
In general, the mastering process involves adding the final polish to a preexisting mix. This includes leveling, preparing for distribution, and making sure that the project as a whole is cohesive. Let’s dive into a couple of tips that illustrate what that process is like for vocals.
#1. Keep Mixing and Mastering Separate
With any aspect of a song, especially vocals, it’s important that you’re giving the mixing and mastering processes their own space. This is because the philosophy behind mixing involves deep adding/subtracting, sometimes involving an entire rework of a track.
When you master, you are looking to polish and heighten the parts of something that is already complete. By keeping the two operations independent of one another, you allow for your vocals to be better thought out in terms of context (mixing) and the overall level/vibe of the song as a whole (mastering). A good master on a bad mix still produces a poor track. Therefore, make sure you do your homework before jumping into the world of mastering plugins- The real work comes out during mixing.
#2. Know your Vocals
What type of voice is presented on your track? What kind of frequency is it lacking? Is your vocal the focus of your song or more in the background? It’s vital that you consider these questions deeply before beginning the mastering process so that you have a clear roadmap to lead you down the right mastering path with plugins that fit accordingly.
#4. Use a Reference Track
Vocals are by far the trickiest aspect of understanding audio engineering since they are so unique. It can be extremely helpful to use a reference track during the mastering process to get your vocal exactly where you desire. Moreover, so many of these free plugins include bypass features, sometimes for each separate band, which makes it easy to compare against your model track.
Mastering is the icing on top of the cake, not the cake itself, but that does not diminish its importance- especially with vocal tracks. A good master sets your music apart and is a mark of a seasoned producer. Try out one of these free vocal mastering VSTs on your next track to get you one step closer to the coveted warm, thick vocal our ears crave.

MCompressor by Melda Production (Windows and Mac)
MCompressor is a very nice and very versatile vst compressor plugin. It has a good graphic user interface (GUI) that gives you good visual feedback about what you are doing both in terms of how you are compressing (soft knee, linear, or hard knee) and how much gain reduction you are employing.
You have full control over attack, release, ratio and threshold and you can target either the audio peaks or the average loudness (RMS) of the incoming signal – or set up the MCompressor to target the audio signal somewhere in between these two.
MCompressor also has a sidechain and a highpass and lowpass filter which makes it extraordinarily flexible. It comes with the Melda Free Bundle that includes quite a few other nice vst plugins. Highly recommended.

DCA1 by Klanghelm (Windows and Mac)
The DC1A compressor from Klanghelm is a simple yet powerfull free VST compressor plugin. If you are a beginner this could be a good compressor to learn by since it is very easy to tweak plus you are forced to use your ears and not rely on numbers.
The DC1A is resembling an OPTO compressor. Its attack and release timings are program dependant although you have the choice between a faster response (which is the default mode) and a slower response with the ”relaxed” mode engaged. It has a fixed threshold and the more you gain the input the more compression you will get.
Use the output knob to match the compressed level to the uncompressed. This way you will not be fooled by differences in loudness between the unprocessed and the processed audio.

The DC1A can add a nice saturation effect to the audio. The saturation is stronger with higher gain reduction. You will have less saturation when the ”relaxed” mode is enabled. If you use it for just a few db of gain reduction in ”relaxed” mode it will work in a much more transparent way.
On stereo tracks you can compress the left and right side separately by enabling the ”dual mono” mode and Klanghelm has also given us an internal sidechain high pass filter which comes in handy when you want to keep the low end more intact (for instance on the drum bus). Finally you have the option of using negative compression ratios.
So, even though the DC1A looks simple at a first glance it is quite surprisingly versatile and can work well on many different types of audio material from drums and percussion to vocals, guitars, and keyboards. It is a very good sounding free VST compressor and should you want even more flexibility you should check out its ”big brother”, the DC8A, which is a high quality compressor with a lot of tweakability for just a little more than 20 US Dollars.

MJUC jr by Klanghelm (Vari-Mu compressor) (Windows and Mac)
Yet another simple but powerful vst compressor plugin by Klanghelm. MJUC jr is a scaled down version of the amazing MJUC compressor plugin by Klanghelm. However, the MJUC jr still gives you a little of the flavour that you will find plenty of in its bigger sibling. Both plugins are emulations of the Vari-Mu compressors type and thus they add quite a bit of tube coloration / saturation.
With just a few controls – compress, make up gain, and a choice between three time constants (fast, slow, and auto) – the plugin is very easy to operate and you may be surprised about how much you can get out of this scaled down version. If you need more control and would enjoy playing with a lot of extra parameters you can buy the full version for very little money.

TDR Kotelnikov by Tokyo Dawn Records (Windows and Mac)
TDR Kotelnikov is a free VST compressor designed primarily for mastering purposes. It can function in a very transparent way and will definitely also find it’s use as a channel compressor or a group bus compressor.
The developers have added control features that you will not find on many compressors such as separate control over peak and RMS release values and a way to balance the importance and influence of each of these release times on the processing (through the peak crest knob and of course through the peak release knob and the RMS release knob).
You can also control the stereo sensitivity and chose whether the compressor should work on the full stereo audio or on the mid (”sum”) alone or the ”side” (”diff”) alone. If you want to dial in both mid and side compression and control these individually then you can simply use two instances of TDR Kotelnikov.
TDR Kotelnikov offers an internal sidechain function which gives you the option of relaxing the way the compressor responds to low end frequencies. There is also a mix option for parallel compression.
Timingwise the TDR Kotelnikov is capable of very fast settings. The attack time can be as low as 0.02 milliseconds and the release time can be as fast as 10 milliseconds for the peak release and 20 milliseconds for the RMS release. Of course you can choose slower settings as well since the attack time is fully adjustable up to 250 milliseconds and the release time likewise fully adjustable up to 2 seconds. All in all a very versatile tool for transparent compression.
TDR Kotelnikov is a fabulous free VST compressor plugin and it is amazing that you can get this quality for free. For mastering it is one of the best free vst compressors around. Highly recommended.
Should you want even more options there is a ”Gentleman’s Edition” at a very affordable price.

Thrillseeker LA by Variety of Sound (Windows only)
This is definitely one of my favorite free VST compressors and probably the one free VST compressor that I use the most. The Thrillseeker LA is a very versatile compressor. In many ways it works like an OPTO compressor but although some people on the internet describe it as a free version of the LA-2A it is much more flexible than that.
Yes, indeed, the Thrillseeker LA can work very much like an LA-2A but you have many extra options on this Variety of Sound plugin. First of all you have faster attack times (both attack and release times are dependant on the incoming audio material – just as is the case with the LA-2A – but you can tweak and control the timing to some extend with the attack and release knobs).
This means that it is possible to tweak the Thrillseeker LA to work very much like a dbx 160 when it comes to timing – or a Tubetech CL-1B as well as a Fairchild or an LA-2A compresor.
Variety of Sound has also given us control over the total harmonic distortion (THD) with the interstage section. Once you have found the right amount of compression and adjusted the attack and release to your liking you can turn on the interstage section and add 2 order harmonics. If you want to go further than that you can use the slider to add even more THD and obtain thicker saturation effects.
Finally you have the ability to colour the saturation effect to your needs and even switch on a transformer circuit simulation to fatten up the sound even more.
Thrillseeker LA has internal and external sidechain options and in the top left corner you will find a little knob that calibrates the plugin to a conservative (and advisable) mix level of -18 db.
In other words Thrillseeker LA can work as a clean compressor or as a more vintage sounding unit. It can work with much faster attack times than an LA-2A and it has its own little colour tool box in the interstage section.
You can use it as a channel compressor or indeed as a bus compressor. And last but not least: it sounds amazingly good. It proves that free plugins can sound as good as commercial plugins – and be more innovative than most of them! That is just one good reason to dive into free VST compressors and other free VST plugins. Highly recommended.

SAFE Compressor by Semantic Audio (Windows and Mac)
The SAFE Compressor is special in the sense that it allows you to type in more intuitive or descriptive terms or words into the plugins textbox – such as for instance bright, warm, punchy etc. – and if the word or term is on the developers server the compressor will be set to parameters that can bring forward the wanted and described effect.
You can save your own suggestions for semantic terms that represent a compression effect and it can then be shared with other users via the server. In other words SAFE Compressor is a unique intuitive compressor that may be of special interest to beginners.

FRComp87 by eaReckon (Windows and Mac)
FRComp87 is a delightfully simple vst compressor plugin. It only has a few controls: threshold, makeup gain, and three timings (fast, medium, and slow). Finally, you can switch in a limiter to tame peaks after the compression. Because of the simplicity FRComp is very fast to use and may be just the right starting point if you are a beginner when it comes to compression.
Download link: FRComp87

dlm Sixtyfive by de la Mancha (Windows)
The developer de la Mancha has created a really good free VST compressor plugin inspired by the dbx 165 A compressor. However, de la Mancha’s Sixtyfive gives you several extra options compared to the hardware which inspired his work.
If you are looking for a dbx-style compressor plugin Sixtyfive is a good choice. It sounds very good and adds a little, nice coloration and character to the audio material you run through it.
De la Mancha has given you extra features like a dry/wet knob which makes it easy to dial in ”New York” or parallel compression. While the fastest attack on the original hardware is 1 millisecond de la Mancha lets you dial in even faster timings. Like the dbx 165 A de la Mancha’s Sixtyfive also has an auto attack and release button which activates a program dependant attack and release response. It also features a peak stop option for hard limiting on the final output.
Sixtyfive is a soft knee compressor. You can tweak it to give you smooth, musical compression or to work in much more agressive ways. So if you need a vintage style VCA compressor plugin with extra features you need look no further.
–
GComp by GVST (Windows and Mac)
With the GComp vst compressor plugin you have full control over attack, release, threshold, hard knee or soft knee or anything in between as well as dialing in the balance between how the compressor should react to audio peaks versus RMS (the average loudness of the program material). On top of that it also includes a limiter.
You can adjust the input and output volume and GComp gives you a good visual feedback of what is going on and how much compression you are applying.
GComp has a sibling called GComp2 with a few different parameters that you could check out as well.
