## What is Voice Synth Modular?

Voice Synth is a professional live voice processor and music synthesizer played by your voice. With the vast set of integrated tools including Vocoders, Auto Pitch, Harmonizing Pitch Shift and Speed-Shift Sampling, you can

• Sing in Tune like P-Tain & vocoded like Duft-Pank
• Speak with Hollywood-quality Robot voices like 1978 Cylons
• Play by Voice, no fingers needed: scream to play rock guitar, hum a church organ

• Make professional funny voices: animal, evil, weird & much more
• Create unique organic and rhythmic soundscapes
• Sing multiple voices in harmony within any musical scale
• Sample, speed shift and dress up your beatboxing to create the strangest rhythms inspiring new compositions
• Live-pause and stroboscope your voice

• Save and share your creations as presets and audio files
• Use all of the above in your DAW and audio setup via Audio Units & MIDI

This "Modular" version of Voice Synth offers a free unlimited-time tryout of all effects on prerecorded samples, while all other functions are unlocked by a single In-App-Purchase.

On Voice Synth you will find no conventional ADSR, LFOs or filters. Even the keyboard is optional. Instead, Voice Synth uses the most expressive all-in-one tool you were born with: your voice! It's unique so be ready for a jump in voice creativity, sound design and rhythmic inspiration.

To give you an easy start in this adventure, we included over 250 factory presets! Speak, sing, hum and scream live into the mic, and start exploring the unconventional controls: 24-band vintage analog modeling vocoders, Auto Pitch Tracking, live-voice-pause, speed-shift sampler, multiple voice harmony arranger, spectrum stroboscope, pitch and formant shifter, 24-band equalizer, classic FX as distortion/delay/chorus/reverb, and an extensive vocoder designer with oscilloscope. We included a manual for in-depth use.

Musicians, DJs, sound designers, voice artists: Voice Synth is a must-have in your audio toolbox!

### 1/5 — It won’t work

*2026-08-18, version 5.2.9*

Had the app open overnight still wouldn’t open

### 1/5 — On veut te faire de l’arnaque aux gens maintenant

*2026-08-09, version 5.2.9*

L’intitulé de l’App Store du coup l’endroit où je voulais acheter cette application disait que l’application faisait du vocaux mais apparemment c’est pas vrai. En tout cas elle peut le faire mais que sur du simple qui est franchement abusé et ce qu’on attend vraiment pas d’une application le fric je sais pas si vous voulez ça ou quelque chose d’autre en tout cas j’espère la fermeture de votre application bientôt, je suis vraiment en colère, vous avez de la chance que je ne vous mette pas zéro arnaque que je vous mette pas zéro étoile parce que si je vous aurais mis zéro étoile là, ça serait beaucoup plus problématique. Bref, je vous déteste.

### 1/5 — What’s wrong with the audio

*2026-06-05, version 5.2.9*

For some dumb reason the recording doesn’t do anything all it does is make no sound at all

### 1/5 — Ridiculous

*2026-06-02, version 5.2.9*

I paid for this app years ago, and now years later every feature is locked behind a different paywall? Ridiculous

### 5/5 — Hct Ty ga qm

*2026-05-26, version 5.2.9*

Biw

### 5/5 — Dirty for root

*2026-05-13, version 5.2.9*

I like it

### 4/5 — Complet et Fun mais…

*2026-05-11, version 5.2.9*

ATTENTION!!! Achetez cette version extra [ Voice Synth MODULAR] à 9.99€, surtout ne mettez pas un rond dans le trés/trop simple « Voice Synth », ne vous faites pas avoir, la confusion est piègeuse…d’ où l’ étoile en moins.
Sinon c’ est VRAIMENT une appli G.É.N.I.A.L.E. !!! Il y a un paquet de fonctionnalités qui ne tournent pas uniquement autour du vocodeur. Vous pouvez fredonner un air, le sampler et transformer votre voix en synthé ou en « brass » par ex, pour les créatifs du bulbe c’ est le pied total. Fonctionne bien dans AUM, Cubasis 3, etc 
Une pépite, merci aux dev malgré la confusion possible avec Voice Synth.

### 5/5 — Bozz!

*2026-04-17, version 5.2.9*

### 1/5 — 使いにくい

*2026-04-13, version 5.2.9*

とにかく使いにくい

### 5/5 — I’m not sure how to explain this to you

*2026-03-27, version 5.2.9*

Visible
I like this game 
It’s super good But it’s not like the original version of it has a good story or something like it is just not the same as the old ones 
And it’s just not the old ones that are the best version
