# 71-A: Vareschi Spot ("Do You Believe in Vocoders?")

GRP V22 Vocoder (Demo and Sound Tests) This episode is brought to you by Vareschi Mastering. Do you vocode? A good engineer can explain such processes. Ask: https://www.vareschimastering.com/ "A Midnight Drive with a GRP V22 Vocoder" Full episode (four tracks) https://soundcloud.com/eptc/sets/spoken-word-with-electronics-episode-71 The GRP Vocoder Speaks for Itself! After saving up nickles and tree lint for three years, we happily bring a Vocoder into the show. This is the GRP V22. It is easily the most configurable and sonically expressive analog vocoder to ever exist. There ARE a few comparable Vocoders in terms of sound: The Bode 7702/Moog Vocoder is one, as is the Sennheiser VSM-201. But neither the 7702 or the 201 provide 22 channels of speech analysis. Nor do either provide the variety of tone shaping and filtering as found on the V22. But enough typing, just hear it. It's one incredible Vocoder. I call the V22 the Buchla Easel of Vocoders. This show introduces it to the family of instruments in the SWWE studio. It took some restraint to not buy anything for three years. But the joy is pretty nice now that it's here. The vocoder was invented in 1938 by Homer Dudley at Bell Labs as a means of synthesizing human speech. This work was developed into the channel vocoder which was used as a voice codec for telecommunications for speech coding to conserve bandwidth in transmission.
