About 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!
