Making Vocoder-Sounds

Robot-voices are very nice to make cool vocals for music like electro and oldschool hiphop. The history of vocoders is very long, you can find a lot of information by looking on websites like wikipedia etc. Some crews like Kraftwerk, Knightz of bass, Grandmaster Flash, Freestyle, Bass Partrol, The Alliance, Man Parrish – Boogie Down (Bronx) and a lot of other artists used a vocoder, often the Roland SVC-350.

There are many ways to make robot-voices, some of them are hardware-based, some are software based. I like to write here some informations i found in the internet.


Roland SVC-350

The Roland Vocoder is the first truly sophisticated Vocoder to be priced within range of most musicians. The primary function of the Roland Vocoder is to analyze the spoken or sung human voice and use this information (or program) to trigger another musical signal (or carrier) giving the instrument the ability to ’speak.‘ This vocal synthesis is accomplished by processing the voice through a series of eleven Voice Character analysis filters. All of the filters within the Voice Character control are active and control an envelope follower which reacts according to the volume of that individual frequency. This information is then used to shape those frequencies of the carrier (musical instrument) signal. (found at )
