Image-Line Vocodex v1.0 Full
Vocodex is the last word in vocoders, featuring advanced articulation envelopes, integrated Carrier synthesizer and Soundgoodizer maximizer, vocoder envelope control and up to 100 variable-width multi-parameter vocoder bands. Vocodex - By your command!
Vocoding is the process of using the real-time frequency spectrum of one sound (Modulator) to modulate the frequency spectrum of another (Carrier). The vocoder engine consists of a series of bandpass filters that allow through only those frequencies detected in the Modulator source. So, for example, when a human voice is used to modulate a synthesizer chord, it will sound like the synthesizer is talking, the classic robot voice from many sci-fi movies.
