Get to Know the Modules

VocalSynth 2 features five, blendable eccentric modules: Vocoder, Compuvox, Polyvox, Talkbox, and Biovox, a new type of effect based on the dynamic sonic qualities and physiology of the human vocal tract.

The Biovox Module

Create and manipulate your biological imprint with a brand new vocal effect. Using scientific modeling of a human vocal tract, adjust human vocal characteristics like nasality, vowel shapes, and formants for a smooth, textural vocal treatment to any audio signal. Use surgically to adapt takes to better fit your production or apply as a creative effect to make a vocal more present, breathy, or totally mangle it!


The Compuvox Module

Compuvox is based on a technology known as Linear Predictive Coding (LPC) which has existed since the late 1960s. As with a number of the audio processors in VocalSynth, LPC was originally a communications technology for encoding intelligible speech at low bit rates to save bandwidth. Nowadays this computerized vocal sound is often used as a special effect common in electronic music production. The outcome sounds similar to infamous toys like the Furby, Speak n Spell (which uses LPC), and even older text-to-speech technologies.

The Polyvox Module

Polyvox is a voice generator that allows you to create vocal harmonies based on your vocal. Voice generators come in all shapes and sizes but are based on a similar fundamental concept: sampling an incoming audio signal and then creating multiple additional versions of this audio signal using time/pitch stretching to achieve different intervals, such as an octave down, a third up, and so on. Voice generators are most commonly used on voice but there are many examples of this type of technology being used in guitar effects as well, usually some combination of pitch/whammy adjustment.

The Talkbox Module

The Talkbox module emulates the effect of a hardware talkbox effect popularized by rock artists such as Peter Frampton, The Who, and Stevie Wonder. A talkbox imparts vocal characteristics on an input source (a guitar, for example) by driving the output of an instrument through a tube that terminates in or around a performer’s mouth. The signal is then filtered and modulated by the mouth, tongue, and lip movements of the performer. The resulting effect sounds as though the guitar is “speaking” or “talking.”

The Vocoder Module

As with a lot of today’s musical technologies, the vocoder (short for voice encoder) began life as a completely non-musical, utilitarian piece of electronic equipment. Throughout the decades, it’s been used by some of the most innovative artists in the music industry, including Laurie Anderson, Stevie Wonder, and Kraftwerk.
