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 Inter-App Audio (iOS), 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! Voice Synth is available on the iOS and Mac App Store, and has a dedicated interface designed for iPad/Mac, and a compact interface for iPhone/iPod Touch that includes all features so you can create anywhere you go.

Studio Eyeball ,

I gave it a chance.

Yes, the demo could have been longer to give people a chance to see if this app was right for them.

I took a chance on this app and was fairly impressed by the huge array of filters and how easy it is to make a nice beat out of your voice. There is also an editor to create your own filters, though I haven’t been able to make something that sounds good yet.

One con is that, while the developer worked hard on the interface, it took me the best part of an hour to figure out the workflow. (Record Sample->Select Preset->Record Tape->Perform->Export Tape). I kept recording tapes and wondering why I couldn’t play them in the piano. It would be nice if the layout of the app was more intuitive.

Anyway, the large amount of negative reviews seems over the top, as this seems a perfectly decent app. Come on, it’s less than you’ll spend on a McDonald’s meal.

Hi Studio Eyeball, thanks for your compliments and support. Note we changed the free trial to unlimited duration since V5.0. So you can get a good impression of the incredible quality of this voice processor without purchasing anything. Your remark on the record button we understand it, and take it with us for future updates. Thanks, Qneo.

Doesn’t work right with Garage Band! The option to use a live mic disappears when integrated with GB! 🤷🏻‍♂️🤦🏻‍♂️
I upgraded to PRO cos it said to unlock all functions within GB you needed to upgrade to pro, so I thought that was the problem. Nope, just wasted $6 & I want a refund.
I was originally got this cos I injured my hand (guitarist) and still wanted to write music so I thought I’d hum into this and have it come out as MIDI in GB.
Seems like a pretty simple idea doesn’t it?
To me this is useless. Save ur money.

Developer Response ,

Hi MT Tombs, Voice Synth is completely compatible with all features in Garageband, including live mic input. Please read our manual:, which is also accessible from within the app (the button named... "manual"). It contains a full section dedicated on how to use Voice Synth with Garageband (both with inter-app-audio and audio units), including step-by-step instructions. In essence, when hosted by Garageband, an app only gets input from the host. Which may be live input from the mic, or it may be audio recorded on a track. For more assistance, you can contact us at Please let us know by mail or in your review if this helps you out. Thanks, Qneo
