Vio For iOS A Psychedelic Vocal Synthesizer


Developer Square B has released Vio, a new iOS app that lets you tranform your voice using a psychedelic user interface.

Here’s what they say about it:

The innovative audio engine behind Vio goes far beyond existing voice effects to create novel, futuristic vocal styles. Vio’s sound spaces vary in character from edgy and energetic to mellow and relaxing. Vio surprises and inspires your creativity: you may not intend to do something, and it comes out cool. Whether you are an amateur or seasoned professional, Vio’s pitch correction technology ensures that everyone sounds in tune and is beautifully harmonized.

Here’s a video overview of Vio:


  • Touch Control – Explore each sound space by touching Vio’s swirling particle vortex. Move the vortex around the screen and change how your voice is transformed – harmony is added or subtracted, melodies emerge and disappear, and reverberations shape shift.
  • Looping – Double-tap the screen, loop what you have just sung or hummed, and focus on morphing your sound with the particle visualizer.
  • Recording & Sharing – Record your performances and share them via email, SoundCloud, Dropbox, or iTunes file sharing. Choose between compressed and high quality audio files.

Here’s a video tutorial on Vio:
