I guess you would have to agree with me that the best way to polish your vocal recording or a vocal sample is to sprinkle some effects, just like the way you would sprinkle a reasonable amount of ingredients on your food. If done right, it sounds delicious right, yum yum 😉

Vocal effects are no exception to the ingredient perspective, you need to add a reasonable amount of effects to make them sound lively, and enjoyable to the listeners.

Don’t get me wrong, I ain’t saying you should stack effects upon effects on your vocal samples, too much of everything is bad. That said, let us look at the best free awesome VST effects plugin in the music production scene.

Let’s ride on…

1.) AegeanMusic – PitchProof

If you haven’t heard of PitchProof, then, you are definitely missing out, this is like the secret tool I use on Vocals but it wasn’t even developed for Vocal, it was actually designed to work on monophonic signals such as guitar solos, but I’ll give you a tip on how I have been using it:

You don’t want to apply it in realtime, what you should do instead is to first select the key of the harmony, then you turn the Blend knob all the way to the right; wet e.g:

Export the vocal result, add whatever effects plugins you gat on your toolbox (vocal, flangers, etc) to spice up the pitched vocal, and then stack it on top of the original vocal. Boom, you have something unique!

Note: You don’t have to always push it all through the wet side as this might cause artifacts, just experiment and stick with what works for you.

You can even export more vocal, and maybe this time, you can try by reducing the detune knob, anyways, experiment until you get your preferred test.

That said, let’s look at some of the features of PitchProof:

The Blend control knob would let you adjust the level of pitch shift, while the Pitch drop-down menu lets you select pitches like +7 or -7, or harmonies which are intelligent pitch-shift effects.

Moreover, there are also some options at the bottom of the PitchProof plugin which give you the option to switch between stereo and mono; mono could save your CPU, while the stereo option could cause a resource hog if used on multiple inserts.

Transient Fix can be switch on or off to spice things up a little!

2.) Auburn Sounds – Graillon

This is an autotune VST plugins designed and developed by Auburnsounds. This plugin is superb in the way it handles pitch correction.

It not only supports pitch correction but supports the generation of throat sounds, making octave sounds, enriching, and enhancing vocal expressiveness.

Also, there is a pitch shift parameter that transposes vocals up and down in octaves and semitones.

Features:

• Pitch Shifter cleanly transposes a voice up and down and has been optimized for voice.
• Pitch Correction module brings an immediate robotic sound, while the Bitcrusher addition softly adds sparkles to the mix.
• Freemium

System Requirements

3.) JHudStudio – Vocal King

Vocal King helps glue the vocal in a mix, and it comes preloaded cool parameters, that could help in customizing the audio signal of a vocal track.

The Pres Compressor knob helps in bringing out the clarity of a vocal, so, by turning up the gain of the Pres Comp brings out the presence in the vocal along with giving it a smooth compression. On the other hand, the Low cut, Tighten, and the Bass knob compliment the Pres Comp in taking out muddy frequencies without the vocal sounding too thin.

I also love playing with the Crispy knob as it sprinkles some sparkles to the audio signal.

Features:

• Help vocals to stand out in a mix by giving them amazing presence, clarity, and compression. Can easily work on any other content.
• Acts like are preamp giving the signal a strong boost.
• Easy to use interface for fast results.
• Easy to read meters
• Very CPU efficient compared to other types of plugins.
• It can be used on many other audio sources as well.

System Requirements

• Vocal King supports MAC/Windows/32bit/64bit/VST2/VST3/AU. Supports MAC OS X 10.7 / Windows 7 and higher. Older systems may not work.

4.) Sonic Anomaly – Vola

Vola is a Voice Optimized Leveling Amplifier made for broadcast voice dynamics processing, it also works with different kinds of audio material, like drums, percussive instrument, and synth pads.

This fantastic tool is solely for cleaning up sound files but can be used for extreme compression effects as well.

Features

• Real-time Visual Metering for changes in dynamics
• Upwards & downwards compression, each separately adjustable.
• Stats Display and more compression settings

5.) g200kg – KeroVee

This is a pitch correction VST plugin tool and has strengthened to support natural pitch correction.

This tool is handy and can perform different and various types of voice effects, for example, a conversion of the male voice to a female voice and vice versa.

KeroVee comes bundled with useful parameters for the effectiveness of the auto-tuning process, Parameter includes:

• Scale Button: This is for specifying the scale you want to tune. Setting a wrong scale would result in an awful result, in a simple sentence, Know your scale before you go into this one
• TuneSpeed: This will allow you to set the speed of correcting the pitch.
• Nuance: This is one of the best and lovely parameters, you can use this to set a fine vibrato of the original sound, use this to create all sorts of weird effects.
• Amount: Set to zero (0) if you want no correction, setting to 100 will result in full correction of the pitch
• and many more parameters like Transpose option, master volume, etc.

System Requirements

• A compatible host program that supports the VST formats

6.) Martin Eastwood – Duet

Have you heard those natural double effects in some tracks! Do you wonder how those are created? I guess yes 😉

Let me introduce to you – Duet, a double-tracking effect designed to enhance your audio sample be it vocal or even instruments, Duet is well capable of sparkling them up. The way Duet work is by pitch-shifting both the left and right inputs individually using a novel synchronous overlap and add technique, allowing pitch to be manipulated in real-time while still maintaining the time duration of the audio.

One thing I love about Duet is the way it can accurately create the illusion of multi-voices and adds varied texture to the mix. Experiment with Duet to see how it works.

Note: This is only available for Window

7.) MaxSynths – DSP-2

DSP-2 is designed with an intelligent Dynamic Processor, a 4-band equalizer fixed on vocal key frequencies, a saturator, and a room emulator based on the Schroeder reverberator. DSP is super simple to use and can serve basically all your vocal processing needs, again, experiment and keep experimenting to get the best settings that would soothe your need.

Features:

• Intelligent Dynamic Processor (IDP).
• 4 different automatic operative modes.
• Selectable compression ratio.
• Saturator with three different operation modes.
• EQ fixed on vocal key frequencies.
• Room emulator based on the Schroeder reverb model.
• Transparent increment of the perceived volume level.
• High precision input/output VU-meter.
• Low CPU usage.

8.) Distorque – Azurite

Azurite is a vocal effect by Distorque which is built for multi-voice chorus with a focus on rich sounds and versatile controls.

According To Distorque:

My goal in designing it was to make as flexible a chorus as possible without losing great tones and ease of use. The result is an effect that will be handy for producers, guitarists, and glitch lovers alike.

One of the great features of this plugin is the way you can create multiple simultaneous voices. Each of these voices can be further customized with their own delay line that is modulated by a separate LFO. Adding multiple voices leads to a thicker, smoother, and less wobbly tone. It also makes vivid stereo spreading possible with a mono signal.

The voice control helps you to choose how many voices you want for the chorus, e.g one, two, four, or eight.

Features:

The human voice is one of the most dynamic musical instruments, and therefore presents unique challenges when recording and mixing. Here are the plugin compressors that I find myself using most frequently when I mix vocals.

1. The 1176/LA2A Combo

Plugin emulations of these two classic compressors are a dime a dozen. While I have my own preferences, most on the market are pretty great and are mostly faithful to their hardware counterparts, and at a fraction of the cost. Individually, they’re wonderful tools for mixing vocals, but when used in series (and in a specific way) they’re on a whole new level (pun intended).

Mix Tip:

Start with the 1176, and set it so that only the loudest passages of the vocal performance are being compressed. A medium-to-fast attack/release should do the trick, and tweak the input/ratio so you see the desired amount of Gain Reduction. Next, insert an instance of the LA2A after the 1176, and set the Peak Reduction knob so that you’re getting a couple of dB of compression at any given moment.

The idea is that the faster or “grabbier” 1176 handles and tames the loudest peaks so that the LA2A is never pushed too hard and can focus on general, consistent compression duties. The resulting sound is smooth, warm and natural. If you’ve never done this — try it now. If you’re more of a visual learner, below is a video of the technique being applied.

2. FabFilter Pro-C 2

FabFilter has a different approach than most plugin companies. While most are creating tools that faithfully mimic the sonics and controls of tried-and-true hardware units, FabFilter has always been more interested in developing state-of-the-art plugins, complete with highly scientific visual interfaces and endlessly tweakable parameters.

For surgical work, which I find myself doing often when mixing vocals, they’re indispensable tools. If you’re interested in learning what compression actually does, the Pro-C 2 is a fantastic learning tool. The eight distinct compression “styles” built into the Pro- C 2 (including one especially for vocals) really place it head-and-shoulders above the competition when it comes to versatility.

Mix Tip:

In Pro Tools, I route all of my audio tracks through one of several sub-aux tracks. Generally, these auxes consist of Drums, other instruments, vocals and effects. I insert the Pro- C 2 on the instrument buss and using the vocal signal to trigger sidechain compression, subtly duck everything around the vocals. I’m not talking intense, EDM-style pumping, I’m talking one to two dB of gain reduction at most. This technique helps establish a defined space for the vocals, as instruments like guitars and synthesizers sometimes occupy the same frequency range as singers. I also use the kick and snare to trigger compression if they need to be a bit more prominent.

3. UAD Distressor

The Distressor is one of the most flexible hardware compressors, offering a lot of dynamic and tonal control over whatever you run through it. It’s one of those units that can be used transparently, but has a very distinct sound when it’s pushed.

I commonly apply well over 10 dB of Gain Reduction on vocals with this thing, and it still sounds awesome. Very few compressors can handle this kind of abuse while still sounding natural. The UAD version meticulously emulates all of the features of this wonderful unit, and in addition, incorporates the all-important Dry/Wet blend knob.

Mix Tip:

Use the “band emphasis function” of the detector for taming harshness. What this does is make the unit more sensitive to nasty, mid-range frequencies. For singers that have a build-up in the mids, this feature really takes the edge off.

4. Softube/UAD Tube-Tech CL 1B

Another sought-after hardware unit that has been faithfully reproduced, available as a Softube Native plugin, and also for those of us that have UAD Hardware. When I want to achieve a smooth, warm sound, quickly, I reach for the CL 1B. If I’m in a pinch and don’t feel like going through the 1176/LA-2A gain-staging process, this is my go-to.

Mix Tip:

The Softube Native version has a sidechain option, so I use it similarly to the FabFilter Pro-C 2 method mentioned earlier. The CL 1B is not as precise — but is a great option when you’d like to add a bit of color to your signal.

5. Waves V-Comp

Modeled after a vintage Neve 2254 Unit, but updated with some more modern features, I find myself using the V-Comp for pretty particular applications. It doesn’t work on every singer, but when it does work, it’s a special sound. It’s not as precise and variable timing-wise as the other compressors here, but sometimes it’s just what a vocal needs. The De-esser makes it even more vocal-friendly.

Mix Tip:

The V-Comp is great for achieving an upfront sound. If you want your vocal to pop and sit closer to the listener than other elements, the V-Comp is my go-to. That said, it takes some tweaking to achieve what you want, but when you hit the sweet-spot with the V-Comp, you’ll know.
