REAL ANALOGUE VOCODER LIST by syntheiszerforum @ moogulatorium
Voice Coder = Vocoder - analyses frequency ranges from the original and transforms it to another frequency section

Note: Kraftwerk used a machine called Votrax (Siemens), its a phonetic Generator, so it is NOT a Vocoder.. but of course they also used vocoders (a lot)..
Homer Dudleys VODER is one of the first made (late 1930ies/ very early 1940s)
(the vocoder was invented for the war (again) to encode and decode spoken messages..)

And most poeple who tell about vocoders basically mean "there's some tech gadget mangling the voice" but - in fact it's often a harmonizer (indie / pop music / song writer), auto tune (Mainstream Pop), or just a reverb / distortion (EBM/Industrial) - but vocoders are those sounding like ... the Kraftwerk Robot thing and are sort of a singing synthesizer - it's basically checking a few frequency bands, exchanging those bands and playing it back replacing the natural sound source by a synthesizer (mostly pads with certain amount of upper harmonics like rich string pads) to reproduce consonants and s and f noises (which can be coloured noise but as a whole it must be something tonal if you want to play melodies). so there's an analyzing part and a synthesizing part, one that transforms the microphone (or drum loop …) signal into those band filtered 8 or 16 bands (sometimes more) and so to say "sorts" out which frequency group plays a role in your stream of speach / singing.. and afterwards that synthesizer voice plays it back, maybe you have assigned those frequency bands to other bands, so this makes it sound a bit different - note - this was made to chipher encode signals - so this is just a bit simpler because you still want something that makes sense "musicially". so - here you go - the oscillator is that synth carrier signal and will play as much harmonics as that back to the designated band.. and now you have it - we are the robot'sssss... some original direct signal will help to understand what your robot is saying..

Korg VC10 1978/79 - 8 band, not routeable, (D) nicht routbar
Korg VC10 Vocoder
Korg vc-10 vocoder .. eg used by Cabaret Voltaire..

EMS Vocoder 3000 - route-able, 16 band - hi-end!..
and the big one: EMS vocoder 5000.
the EMS Vocoder
with possibility to rearrange the bands and -of course- pin matrix.

Analog Lab Vocoder
(new, from france, 32 band vocoder but not routable, hi quality - (D) neu, aber gut aus F, 32 band, nicht routbar)
Analog Lab from france, 32 bands with LFO
not too many controls but very good sound quality!


very hi-end vocoder (32bands)

Sennheiser VSM201
a picture from my site, click here...jpg

Sennheiser Vocoder VSM201
made in 1978
this is a luxury 20bands vocoder
fully analogue
of course only the "creme de la creme" used THIS, because it is really not cheap.. kraftwerk!

manual can be found here.
as you can see: you can assign all bands freely and tune it!!
the "voice coder = vocoder" is not only for "robotic" voices like kraftwerk did. It's also interesting for rhythmic sound sources.

you won't worry about speech clearness anymore..
the vocoder was first a military device to encode speech signals.. but now "human kind" uses vocoders for music! also a good thing!

Sennheiser Vococer VSM201
--> all pics are much larger! just klick them to see them enlarged..
