… is usually an effects pedal that sits on the floor and contains a speaker attached with an airtight connection to a plastic tube … the speaker is generally in the form of a compression driver, the sound-generating part of a horn loudspeaker with the horn replaced by the tube connection. 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?Īuto-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. 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. + Inbuilt carrier synthesizer powered by Sytrus.Vocoders have been around since the method was used first to synthesize a human voice in the 1930s. + Sidechain carrier & or modulator input. + Band unison to create a fat & lush sound. + Up to 100 bands individually locatable anywhere in the spectrum. + Built-in Soundgoodizer for limiting and warm output.
+ Voice doubling and reverb capabilities. + Modulator noise reduction to reduce ambient noise bleeding through carrier. + Speech enhancement contouring of noise or modulator pass-through. So if a human voice is used to vocode a synthesizer chord, it will sound like the synthesizer is talking.

Vocoders analyze the real-time frequency band activity of one sound, the Modulator, to control frequency band activity in another, the Carrier.Ī 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. Vocoders are the classic robot voice from many sci-fi movies. What is Vocoding? You have heard vocoding many times, even if you don’t know what it is. Vocodex is simply one of the best sounding vocoders on the market today.
