In other words, only the frequencies that are present in the modulating signal are retained in the carrier signal after the envelope is applied. Commercial vocoders used as musical instruments consist of a keyboard synthesizer (for playing the carrier sounds) and a microphone for picking up the voice of the performer (to extract the modulation envelope). Then the modulator may be a voice, and the carrier may be any spectrally rich sound such as wind, rain, creaking noises, flute, or other musical instrument sounds. Let’s call the first signal the `modulating’ signal, and the other the ’carrier’ signal. A typical example is to impress speech on various natural sounds, such as ‘talking wind.’ Vocoding is a form of Cross Synthesis, which is nicely described here by Julius Smith:Ĭross-synthesis is the technique of impressing the spectral envelope of one sound on the flattened spectrum of another.

There is some confusion regarding the difference between these processes which should be cleared up first: For a brief history of the Vocoder and some of the artists that have used them, see Ian Vargo’s excellent article here.Īuto-Tune vs. The word itself is derived from combining the words VOice and enCODER.
