Virsyn Cantor Voice Synthesizer Now Shipping

Virsyn has announced that it it now shipping the Cantor voice synthesizer.

Cantor is a realtime vocal synthesizer, that lets you enter lyrics in plain English, and then have them sung by playing the melody on a MIDI keyboard. Expression can be added with realtime parameters controlling vibrato rate and depth, or by changing the character of the singing voice from female to male.

Cantor goes beyond creating realistic “human” singers. Many parameters have no relation to human vocals, like “Metallize” which turns the virtual singer more into a singing Gong.

The voice editor allows you to edit the character of your virtual singer by defining the base spectrum for vowels and consonants.

For those of you ever wanting to create your own alien language the Phoneme editor gives you full access to the atoms of the vocal synthesis engine. With this editor you can define the formant structure and the noise characteristic of each phoneme used by the vocal engine.

Edits are immediately audible in realtime.
