 by the company VirSyn, and was based on the same idea of synethesizing the human voice. VirSyn released both English and German versions of this software. Cantor 2, boasted a variety of voices from near-realistic sounding voices to highly expressive vocals and robotic voices.

Technology

Cantor was not based on singing samples, and its results were reproduced by a morphing additive synthesis engine derived from VirSyn's Cube software synthesizer. It is used to generate the 39 phonemes which VirSyn used to reproduce English speech or singing. Each phoneme is created by passing an additive sound source through a formant filter, which morphs between a start and an end state. These filter responses are fully editable, and up to six peaks and three troughs in the formant filter response can be specified as morph points. Cantor 2 offered 20 ready to use vocals in both English and German and added many new voices on top of the original Cantor software, bringing the total to 50 voices.

The sound generator used a combination of additive synthesis and noise sculpting that it used for specifically for the 50 voiced sounds provided by the software as set as a complete set for the unvoiced sounds. The concept of voiced and unvoiced sounds was complicate, but was used to describe how Cantor was able to master its language capabilities of human speech. For voiced sounds, the additive synth controls the pitched component of the sound (vocal cords), whereas the noise synth controls the breath component (whisper). It controlled up to 256 partials, as the user went higher into the octaves, these became grouped for control. For those who had used other VirSyn's software before it, Cantor was familiar grounds and bore many things in common with past synethesizers VirSyn had produced.

Because of its design, it was more like a virtual instrument than intending to be a virtual singer. It never claimed to mimic a real singer's voice and was intended purely for special effects. However, although it was complex, Cantor was considered a simple design overall and relatively easy to use for its purposes.

History

Cantor was released after the original Vocaloid engine was released, and was considered a suitable software to rival Yamaha's Vocaloid engine, then only known in the western hemisphere by the Vocaloids Leon, Lola and Miriam. Cantor reached a level of vocal synthesising that had not been reached at the time its release.

A demo of the software was released, however it require to purchase a eLiscense dongle to be able to download the demo, as well as the full software if it was purchased electronically. The final version, Cantor 2.1 was released on February 6, 2007. Even though updates ceased, the software was never removed from sale.

Reception

For the capabilities of what the software could do, the Cantor software was dubbed "the future of music" and at the time of its release, Cantor 2 was considered ground breaking technology. However, despite its capabilities one of its let down was considered the high price a consumer had to pay for its contents in comparison to other software release at the time. The biggest criticism towards the software itself was its unintelligible results despite being a powerful tool and though improvements were made between Cantor and Cantor 2, it still lacked clarity which put it at a disadvantage against the more realistic sound of Vocaloid. The simplistic design of its interface despite the complexicity of its capabilities was highly praised overall by reviewers.

Cantor was able to create a playground for experimental vocal sounds and give composers a tool for high levels of vocal affects and sounds. However, both Cantor and Vocaloid were based on the same concepts, ideas and shared a number of similar designs. It was unable to escape comparisons between itself and Vocaloid, although use of both software by musicians at the time was also not unheard of.
