The History of the Vocoder

The first-ever vocoder was developed back in 1928 by Bell Labs and first exhibited in 1939 at a fair which was conducted at the New York. 

Initially, the proposed usage of it was to decrease the bandwidth of voice information, enabling it to be transmitted throughout the further distances. 

Unluckily, the reformation of the voice of those early systems was not so impressive and hence, they never got used for this purpose. 

Nevertheless, they were utilized to send encoded messages during the period of the Second World War. 

How does it work?

Roland VP 330 Vocoder Plus

The working mechanism of vocoder revolves around analysing the sound of a modulator signal which is the voice of a human being. 

Then the modulator signal is divided into further varied frequency bands where the level of every individual band is transferred as a signal to a relevant bandpass filter. Similarly, the filter has an identical frequency that was analyzed and a sound source, known as carried is transmitted through the centre of filters. 

Each bandpass’ level gets adjusted automatically to correlating frequency in the modulator carrier signal. That way, the carrier is filtered so that the harmonic content which goes through is parallel to modulator signal. 

The use of vocoders never came into existence for civilian communication due to the machinic sound that it produces. However, it can be used for creative motives. 

As far as musical use is concerned, a synthesizer is frequently used as carrier frequency which lets it pitch to certain notes. 

Vocoders achieved a lot of fame for musical use in the 1970s by popular artists including the likes of KraftwerkBoney M and Wendy Carlos

Similarly, it is also quite frequent in advance music and is used by musicians like Daft PunkBeastie Boys and Zedd

VST Vocoder Plugins 

When you consider vocal processing, one of the most amazing effects one can take the most out of is vocoder VST plugin.

Our Conclusion

If you can afford it, we highly recommend you invest in an original second-hand classic Vocoder like the Korg or Moog, you just can’t beat the analogue sound for quality, however, if you are on a tighter budget, we would suggest looking closely at the Sonivox VST Plugin.

It’s fair to say that whilst the vocoder is definitely in the retro-sounding space, it’s still being utilised in many modern-day pop hits and releases, so well worth adding to your studio synth library.
