I know ya'll are probably just as sick of hearing me moan and complain about vocoders as I am of hearing songs that feature them. But just how much do you truly know about the instrument that has singlehandedly ruined black radio
and eardrums? Allow me to enlighten you.[1]
[Editor's Note: For any "anonymous" lurker that's about to check me on the difference between the vocoder, auto-tunes, and talk-box, get a life. You know exactly what I'm talking about, damnit! Spare me the technical circle-jerk, and take your wealth of knowledge over to Scratch Magazine.]From the
wiki entry.
A vocoder (a portmanteau of vox/voc (voice) and encoder) is a speech analyzer and synthesizer. It was originally developed as a speech coder for telecommunications applications in the 1930s, the idea being to code speech for transmission. Its primary use in this fashion is for secure radio communication, where voice has to be digitized, encrypted and then transmitted on a narrow, voice-bandwidth channel. The vocoder has also been used extensively as an electronic musical instrument.
For musical applications, a source of musical sounds is used as the carrier, instead of extracting the fundamental frequency. For instance, one could use the sound of a synthesizer as the input to the filter bank, a technique that became popular in the 1970s.
Okay, now that we've got the technical jibber jabber outta the way, let's talk music, decade by decade.
1970's
History says The Alan Parsons Project, Giorgia Moroder, and Pink Floyd were the first cats to really mess with the vocoder. I don't really know any of these folks, but I guess I have to provide token representation, so here's "Mr. Roboto" by Styx.
