Now… What's a vocoder?
Who invented it?
It’s Homer Dudley who first introduced his “Voder”, back in 1928! But it didn’t really make it to the music market until 1970, when Bob Moog and Wendy Carlos design their own. The vocoder became pretty popular in music in the late 70’s and early 80’s.
Who used it?
Famous people/bands who used the vocoder are Earth Wind & Fire, Herbie Hancock, Kraftwerk, Midnight Star, Jean-Michel Jarre… As far as charts are concerned, you heard it in “Let’s Groove” (EW&F), “Rock It” (H.Hancock), “Zoolook” (JM Jarre), “Kelly Watch The Stars” (Air), “Sex Crime” (Eurythmics), “Operator” (Midnight Star)…
