The evolution of vocals 

Elevate your vocal productions with iZotope's most unique plug-in experience for vocals. Quickly get old-school sounds you need, or create a new school of vocal sounds. Get lost in layers, textures, effects, blending, and morphing in an experimental vocal playground, and finally find that secret something that makes your vocals stand out. Choose and meld five unique vocal tools, or pick from hundreds of presets for quick impact.

With a complete graphical redesign and a whole new voice-modeling module, iZotope VocalSynth 2 is a tool designed to transform an input signal—usually a vocal—into a creative, synthetic sound. An instance of this plug-in provides access to five separate vocal engines. You get the four modules from the original Vocalsynth (Vocoder, Talkbox, Polyvox, & Compuvox), and a whole new one called Biovox.

Biovox utilizes scientific modeling of the human vocal tract, allowing you to change aspects like formants, vowel shapes, and nasality in a smooth manner. Use Biovox for subtly-changed vocal doubles when you've only got a single vocal track, or utilize this module as an eccentric sound-design tool.

The effects section has been updated to provide better sound quality, and two new stompbox-style modules have been added to the mix: Chorus and Ring Mod, the latter also serving as an idiosyncratic tremolo effect. As with the previous version of VocalSynth, you can use the plug-in in various modes, including Auto Mode (requiring no MIDI or sidechaining), MIDI Mode (imparting the consonants, formants, and vowels of a sidechain inpun upon the MIDI synth); and Sidechain Mode (applying the quality of the vocal to an audio source, say a guitar for example).

This plug-in also allows for inter-communication between iZotope plug-ins, meaning you can seamlessly integrate VocalSynth 2 with Neutron 2, Ozone 8, and Tonal Balance Control. VocalSynth 2 can be seen and manipulated within Neutron 2's Visual Mixer and Masking Meter as well. This software is compatible with Mac and Windows platforms, and supports AU, VST, and AAX formats.
