What is Vocoding? You have heard vocoding many times, even if you don’t know what it is. Vocoders are the classic robot voice from many sci-fi movies. Vocoders analyze the real-time frequency band activity of one sound, the Modulator, to control frequency band activity in another, the Carrier. A vocoder consists of a series of narrow-band frequency gates that allow through only those frequencies from the Carrier that are detected in the Modulator source. So if a human voice is used to vocode a synthesizer chord, it will sound like the synthesizer is talking. Check the demo tracks above.
