The Talk Box is also a very different process: But the process is significantly different from vocoding. You begin to get that robotic vocoder-esque sound when you push it hard so that the pitch jumps abruptly from note to note. Random thought: What would happen if you Vocode a Vocoded signal?Р”Р„uto-Tune is designed to sort of quantize a vocal signal to the closest pitch or scale degree. In software, vocoders can usually function as inserts on an audio track, as an instrument on a virtual instrument track using a sidechained input from another audio track or a live external source, or in the case of devices like Vocal Synth 2, either as an audio insert effect or virtual instrument. 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. LetРІР‚в„ўs call the first signal the `modulatingРІР‚в„ў signal, and the other the РІР‚в„ўcarrierРІР‚в„ў signal. A typical example is to impress speech on various natural sounds, such as РІР‚Вtalking wind.РІР‚в„ў Vocoding is a form of Cross Synthesis, which is nicely described here by Julius Smith:Р”В¬ross-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 VargoРІР‚в„ўs excellent article here.Р”Р„uto-Tune vs.

The word itself is derived from combining the words VOice and enCODER. Vocoders have been around since the method was used first to synthesize a human voice in the 1930s.
