## What is Voice Synth?

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

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!

### 5/5 — Odd knobs movement

*2026-04-05*

I LOVE this app since IAA, but could you please please please fix this absolutely terrible knob movement???

### 1/5 — Important! This app is kind of unusable! User do not purchase and waste your money

*2026-03-14*

Review: Voice Synth (iOS App) 

I was excited to try Voice Synth because the concept is interesting, but unfortunately the app is practically unusable with modern iPhones. The app seems to rely on using wired headphones with a microphone, which older iPhones supported through the built-in headphone jack. However, most current iPhones no longer include a headphone jack, and the app doesn’t appear to be designed to work properly with wireless Bluetooth headphones or other modern audio devices.

Because of this limitation, many users simply won’t be able to use the app the way it was intended. Unless you have specific wired hardware or adapters that work with it, the core functionality becomes extremely difficult—or impossible—to access. For an app that relies so heavily on audio input and monitoring, not supporting common wireless audio options is a major drawback.

In its current state, the app feels outdated and not compatible with the way people actually use iPhones today. Updating the app to properly support Bluetooth headphones and modern audio routing would make a huge difference. I would also give it five stars.

**Developer response:** Hi Charles, when using AirPods, please open the AUDIO MIDI panel and select your device’s built-in mic as audio input. That reduces much latency, and bring back the totally-out-of-this-world experience of not only hearing but also “owning” Voice Synth’s real-time transform of your voice. Lowest latency is obtained with a with wired (USB-C) headset. For more assistance you can contact us at contact@qneo.net. Thanks, Qneo

### 1/5 — This is a toy at best!

*2026-01-26, version 5.2.9*

There’s no provision to connect the app to whatever audio interface you’re using and use a higher quality mic…only a Bluetooth or iPad mic??? The same with midi….bluetooth only. Apparently this app is more for consumer tinkers

### 1/5 — NO LA COMPREN

*2026-01-22, version 5.2.9*

ACABO DE TIRAR MI DINERO. 

no vale la pena pagar 12 dolares por una app tan deficiente. 

es una estafa.

### 5/5 — Une Merveille

*2025-12-02*

Pour les percussions acoustiques, pour se concocter des presets incroyables et s'éclater les paumes sur n'importe quoi, c'est la meilleure de l'AppStore !
En plus...c'est une des très rares qui permettent de choisir son entrée Audio! Depuis cette bouse d'USBC qui coupe les micros de l'iPad quand on branche un casque, c'est l'une des seules à permettre de contourner le bug. (Uniquement en standalone, hélas.) alors oui, elle commence à dater, mais pour tous ceux qui ont les mains qui démangent en permanence, c'est vraiment l'outil ultime.

### 4/5 — The only stars EcoStar

*2025-10-20*

I’m going on a bike

### 1/5 — Usability

*2025-08-05, version 5.2.7*

Poor usability provides a disappointing experience.

### 5/5 — All of the voices are garbage!

*2025-08-04*

Today, I have done everything I can, but is says to buy that app.

### 5/5 — An Amazing App

*2025-06-08*

I’ve had Voice Synth for years and there is still so much that it can do if I would put the time and study into it. It’s fun if you know nothing about music’ which I didn’t when I first bought it. But as my knowledge grows I am unlocking its true potential. For the price I’d say it’s a great bargain. As my skills and knowledge increase I plan on Voice Synth to be a secret weapon in my quest to make mind-blowing recordings.

### 1/5 — Might be good…

*2025-04-19*

…The UI is terrible. The experience of navigating even the simplest tasks to get into a workflow across multiple applications is too frustrating. If you value efficiency, STAY AWAY. 

I gave it a try at the recommendation of a colleague. Tried the modular “free” version, but the features I really needed to experience weren’t available in it. That’s an annoying red flag. 

Against my instincts (I know), I bought it anyway. Cheap, right? Wrong. I wish I could get that hour+ of fussing around with the app back. My time is worth more than the cost of this app.

That said, you really should let users experience BASIC file functions for free before you make them pay. And Apple needs to get with the program and realize the scammy setup, and return my coffee money.

**Developer response:** Hi Darkemuse, Voice Synth provides all functionality after download (the modular free version offers all effects for free, usable with the built-in sampler). We are not sure what you mean by “tasks/workflow/multiple applications”, but Voice Synth offers audio units that provide all audio effects directly within DAWs like Garageband, Logic Pro, etc. Voice Synth also provides background audio to have its audio effects continue while you use other apps.
