Voice Operated Coder
A vocoder (, a portmanteau of ''vo''ice and en''coder'') is a Speech coding#Categories, category of speech coding that analyzes and Speech synthesis, synthesizes the human voice signal for audio data compression, multiplexing, voice encryption or voice transformation. 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 (computing), bandwidth in transmission. By encrypting the control signals, voice transmission can be secured against interception. Its primary use in this fashion is for secure radio communication. The advantage of this method of encryption is that none of the original signal is sent, only envelopes of the bandpass filters. The receiving unit needs to be set up in the same filter configuration to re-synthesize a version of the original signal spectrum. The vocoder has al ...

Kraftwerk Vocoder Custom Made In Early1970s
Kraftwerk (, ) is a German electronic band formed in Düsseldorf in 1970 by Ralf Hütter and Florian Schneider. Widely considered innovators and pioneers of electronic music, Kraftwerk was among the first successful acts to popularize the genre. The group began as part of West Germany's experimental krautrock scene in the early 1970s before fully embracing electronic instrumentation, including synthesizers, drum machines, and vocoders. Wolfgang Flür joined the band in 1973 and Karl Bartos in 1975, expanding the band to a quartet. On commercially successful albums such as ''Autobahn'' (1974), '' Trans-Europe Express'' (1977), '' The Man-Machine'' (1978), and ''Computer World'' (1981), Kraftwerk developed a self-described "robot pop" style that combined electronic music with pop melodies, sparse arrangements, and repetitive rhythms, while adopting a stylized image including matching suits. Following the release of '' Electric Café'' (1986), Flür left the group in 1987, follo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
