[sdiy] EMS VOCODER 5000 DEMO TAPE

[steve thomas]

Hi all.. Recently Romeo Fahl on the synthdiy list managed to get hold of an
mp3 file
of an original reel to reel tape recording  which demos the EMS 5000 vocoder
(often just called the EMS Vocoder). I have now  edited this mp3 file (12
MB ) down
to smaller files for each track. I for one had never heard the Vocoder5000
before..
some of the sounds are amazing.

Check out track 10..sounds like Steve Hawking on low batteries!!


 EMS VOCODER DEMONSTRATION TAPE.

List of Tracks:

1a) Natural speech with no transformation.
1b) Monotonic spech wothout 'S' sounds.
2)   Monotonic speech with 'S' sounds.
3)   Using a chord from a synthesizer as the excitation.
4)   Pitch extraction with 'S' sounds and ascending pitch.
5a) As 4 but all formants shifted up a quarter octave.
5b) As 4 but all formants shifted up one octave.
6a) As 4 but all formants shifted down a half octave.
6b) Using white noise for excitation instead of the oscillator.
7a) Using noise ecitation with slight slewing of filters.
7b) Pitch extraction and oscillator with freeze.
8a) Monotonic oscillator with slew.
8b) Compressed speech with pitch extraction and 'S' sounds.
9a) Compressed speech with monotonic oscillator and 'S' sounds.
9b) Compressed speech using noise as excitation.
10) As 4 but using voltage control of slew by an oscillator.
11) Using a chord as the excitation but with freeze/slew.
12) Using the vocoder output as its own excitation.
13) Using music as an excitation. An excerpt from Tubular Bells.
14) Using music as an excitation. An excerpt from Autobahn.
15) Imposing male German articulation onto female English speech.

This reel-to-reel tape dated 14 Oct 1976.

BTW I have checked with Robin Wood at EMS and he is happy to allow this demo
to be put on line. The speaker on the tape is Alan Sutcliffe who was a
software engineer at EMS
from 1969-79.

Thanks go to Romeo!

cheers
