VoxSyn turns your voice into the most flexible vocal sound generator ever. Instantly following even subtle modulations of pitch and spectral changes of your voice VoxSyn creates signature vocal sounds far beyond traditional vocoding.

Talk or sing into the microphone and you’ll trigger various synthesizer sounds following your voice pitch or the notes touched on the hexagonal keyboard / external MIDI Keyboard. The basic sounds are selected from a vast pool of predefined sounds from the famous TERA synthesis engine which can be further expanded by its unique random sound generator.

The harmonic table note layout visualizes your voices pitch in realtime and also let you play notes for more traditional vocoder effects.

VoxSyn is Audiobus compatible and can be used in the Input, Filter and Output slots in the Audiobus signal chain.

The output can be recorded to an audio file which you
can use with other Apps and programs for further processing.

Flexible Fast Vocoder


This app has a wide range of presets or you can roll your own. Take input from the mic or use the app as an effect to transform the sound from other apps via Audiobus or an IAA host. Lots of creative possibilities open up for you when using this app.



This app is very powerful, i am having trouble with distortions in audio. I cannot figure out how to stop this. Awesome work none the less.

Vocoder - Synth


Take a drum machine and run its presets through VoxSyns presets sometimes it's muffled noise other times it's magic! Always fun.
