But do you know what exactly is a vocoder?

It’s simple! Vocoders are made to synthesize the human voice!

Although vocoders have been around for many years, they became well-known in the 70s. Luckily, you can now find them in digital form that saves you space and money!

Vocoders allow you to create tunes from mere speech, add texture to an audio piece or even synthesize a choir from a single voice! Plus, if you want to sound design the voice of any robotic creature, a vocoder is a must-have tool in your VST production toolkit.

To help choose the right vocoder for you, in this article, we'll highlight some options worth checking out.

The 9 Best Vocoder VST Plugins of 2021 include:

1. iZotope VocalSynth 2

VocalSynth 2 iZotope

Simply put, VocalSynth 2 presents itself as an evolution of vocal processing of sorts.

Offering an immersive plugin experience thanks to its advanced styling, it comes endowed with features that open doors to new vocal possibilities.

And it does not only elevate vocal productions to suit contemporary needs, but it also grants access to much-needed old classical sound.

Looking at it, you can immerse yourself in layers, textures, effects while experimenting with different blends and shapes before working out the ultimate vocal sound.


At the center of its functionality is a scientific modelling of the human vocal tract.

The technique allows making of adjustments of vocal characteristics such as nasality, vowel shapes, and formants for smooth textural treatment on audio signals.

Then again, it features seven stompbox-style effects section which boosts vocal processing via a custom drag and drop vocal effects chain.

The section includes distortion, filter, transform, delay, shred, ring, mod, and chorus modules all whose order you can alter in line with your production needs.

That's not all-because it further enables interactive visualization thanks to Anemone-a colorful animation feature.

Other features of interest beyond the above include inter plugin communication and three ways to play, namely Auto, MIDI, and Sidechain.

So, you can go for what suits your style for seamless creativity.

In a nutshell, this plugin has been re-imagined to allow the user to achieve better sound quicker and more seamlessly.

And each module has options for pitch shifting, filtering, and modulation using LFO.

That implies one can mix and determine how the four modules interact with each other.

The result is the ability to actualize very elaborate patches.

Vocalizer Pro

To ensure seamless functionality, Vocalizer Pro features two rows of eight MIDI-mappable pads on the interface.

The top enables saving of various presets and parameters for reuse whenever the need arises.

On the other hand, the bottom row can be used for mapping chords for hassle-free sequencing from a MIDI controller.

Although the interface can be a little intimidating at first contact, it provides access to in-depth custom shaping controls.

One particularly striking section is the effects tab that anchors built-in EQ, Chorus, Delay, and Reverb-as well as an effective browser system functioning based on genre, color, and character descriptors.

Besides that, Vocalizer Pro features up to eight snapshot pads which allow on the go access to presets and eight chord pads that help to recall keyboard notes and chords.

9. TAL Vocoder


Summing up our list, the Tal Vocoder is yet another exciting emulation of a vintage vocoder from back in the days.

It not only imitates the sound of vocoders from the '80s, but it also comes with analog-modeled elements though with some digital algorithms.

At its core is an 11-band engine and internal carrier synth with signal options such as pulse, saw, sub, osc, noise, mono, poly, portamento, sync, mode, and tune.


Worth noting, unlike it's some of its competitors, it does not make direct convolution of the carrier and modulation signal.

Instead, it features an envelope follower for each of the eleven bands.

Beyond that, it presents the possibility to route an external carrier signal and greater harmonics control on any carrier signal.

That pretty much implies that every sound source can be used as a carrier signal.

And guess what?

It features a panic button that freezes hanging notes within the synth clip LED that glows once the input signal gets clipped. Isn't that amazing?

Overall, Tal Vocoder is optimized for intelligent voice processing with seemingly endless routing possibilities.
