iZotope VocalSynth 2 Review: Modules, Price & Sales (2026)
Grit up a rap vocal into something machine-like, or drop a robot-voice texture onto a top-line vocal sample — that "treat the voice as an instrument" kind of work is exactly what iZotope's VocalSynth 2 handles in a single plugin. From staples like vocoder and talkbox to iZotope's own vocal-tract model, it packs a lot into one "synthesizer for the voice."
In this article, the Beat Lab editorial team lays out how the five modules actually sound, how to use them on rap and top-line vocals, and the pricing (regularly $199) and Plugin Boutique sale situation, based on iZotope's official information as of July 28, 2026.

What is VocalSynth 2? Five modules that turn a voice into an instrument
VocalSynth 2 is a vocal-processing plugin in iZotope's creative-effects lineup. At its core are five blendable modules, each a different flavor of vocal effect. You can run one on its own, or mix and layer several. iZotope pitches it as "a one-stop for past, present, and future vocal sounds."
What's very iZotope about it is that it connects with other iZotope plugins like Neutron, Ozone, Nectar and Tonal Balance Control (inter-plugin communication), so it's designed with the vocal's place in the mix in mind. It's fastest to just watch it move, so here's iZotope's official demo.

Understanding the five modules with a diagram
The signal flow is simple. Your input vocal (or any audio you like) passes through the five modules to shape its character, then through a stompbox-style effects chain (up to 7 slots) to finish. A two-stage setup. Here's the big picture.
What each module brings
- Vocoder: the classic vocoder. Crafts formants — the module you'll reach for most
- Talkbox: that unmistakable, chewy talkbox sound, with no hardware and no learning curve
- Polyvox: adds rich harmonies and natural doubling to give the voice body and character
- Compuvox: glitchy, computerized robot voice with bitcrushing — great for space-age hooks
- Biovox: the new module added in version 2. Based on a model of the human vocal tract, it lets you adjust nasality, vowel shape and formant position
Being able to blend these five is the heart of VocalSynth 2. For example, thicken your harmonies with Polyvox while mixing in a touch of Compuvox for edge — layering like this lets you build a vocal color no stock preset would give you.
How to use it on rap and top-line vocals (Auto / MIDI / Sidechain)
VocalSynth 2 has three operating modes, and understanding them makes it far easier to use.
Auto mode: it just falls into place
This mode locks your input vocal to key in real time and can generate harmonies and extra voices. With no fiddly setup, just drop it on the track and blend the modules to change the character. It's the quick route to adding a robotic nuance to rap ad-libs or hooks.
MIDI mode: voice as oscillator, pitch from the keys
Here you control pitch with MIDI and use your voice as the "oscillator." Hold a chord and you get vocal harmonies — close to the feel of playing a classic vocoder or talkbox. In iZotope's own rap example, they play chords in MIDI mode and drive a Compuvox chorus. It's also great when you want to layer vocal synth over a top-line melody.
Sidechain mode: make things other than the voice "talk"
This mode lets you feed in your own audio as the carrier signal, so you can make a synth pad, drums or a guitar loop "talk" — sounds you couldn't get otherwise. Top-line texture work is where this mode shines. If you're building the low end too, checking our how to mix 808s and bass after export keeps the overall balance stable.
Unsure about key? Before you program, use our BPM/key detection tool (free) to check a reference track's key so the harmony generation lands more easily.

*Confirmed by our editorial team on July 28, 2026 via iZotope's official VocalSynth 2 product page. Prices vary with sales and exchange rates. Check the purchase page for the latest.
The key point: iZotope is a regular in Plugin Boutique sales. It's $199 normally, but it actually dropped to $29 for a stretch in February 2026 (Bedroom Producers Blog), so if you're buying it standalone, it's well worth waiting for a sale. Unless you're in a hurry, watch the price first. If you're eyeing iZotope tools in bundle, it's efficient to line this up with sale timing for Neutron on the mixing side and Ozone for mastering.
Who it's for / who should think twice
- People making rap and trap who want vocal character: robot voice, pitch-warble, talkbox-style textures — your palette expands fast. Great for making hooks and ad-libs stand out
- People who want to build top-line and texture themselves: making synths or samples "talk" in Sidechain mode is uniquely a VocalSynth 2 thing
- People who first want to nail basic vocal processing: if your main goal is "cleaning up" — pitch correction, compression — a vocal chain like Nectar or timing alignment like VocAlign comes first. VocalSynth 2 is a "flavoring" tool

Frequently asked questions
Q1. Can I use all five modules at once?
A. Yes. Vocoder, Talkbox, Polyvox, Compuvox and Biovox are blendable, and you set the mix in the mix panel. Push one hard, or layer several lightly — either works.
Q2. What's new about Biovox?
A. It's the module added in version 2, based on a model of the human vocal tract. On any audio source, you can adjust nasality, vowel shape and formants — from natural corrections to experimental sounds.
Q3. $199 feels steep. Can I get it cheaper?
A. iZotope is a regular in Plugin Boutique sales, and it dropped to $29 in February 2026 (Bedroom Producers Blog, Feb 26, 2026). If you're not in a hurry, targeting a sale makes a big difference.
Q4. Can I use it on tracks other than vocals?
A. Yes. In Sidechain mode you can feed any audio in as the carrier, so you can make synths, guitars or drums "talk." It's also great for building top-line texture.
Summary
VocalSynth 2 is a "synthesizer for the voice" that gathers vocal processing — from vocoder and talkbox to iZotope's own vocal-tract model (Biovox) — into one plugin. Once you have Auto / MIDI / Sidechain down, it covers everything from rap hooks to top-line texture. It's $199 normally, but iZotope is a PB sale regular. If you're buying standalone, the smart move is to tidy up your tracks with tools like our dynamics analysis while you watch for a sale.
