Vocoders: practice and assortment

Vocoder (English voice coder – voice encoder) – a speech synthesis device based on an arbitrary signal with a rich spectrum. Initially, vocoders were developed in order to save the frequency resources of the radio link of a communication system for transmitting voice messages. Savings are achieved due to the fact that instead of the actual speech signal only the values ​​of its certain parameters are transmitted, which on the receiving side control the speech synthesizer. The speech synthesizer is based on three elements: a tone generator for forming vowels, a noise generator for forming consonants, and a system of formant filters to recreate the individual characteristics of the voice. After all the transformations, the human voice becomes like the voice of a robot, which is quite tolerable for communications and interesting for the music industry.

Vocoder as an unusual effect was adopted by electronic musicians and subsequently became a full- Continue reading

Percussion Recording

Once at the Department of Sound Engineering of the Institute. The Gnesins had a meeting with the famous sound engineer Yuri Bogdanov. He told various stories from his life for a long time that the sound engineer is a complex, ambiguous profession, which often requires knowledge of psychology and the like. Everyone listened very carefully, respectfully, outlined something. When the monologue came to an end and Yuri Ivanovich suggested asking him questions, the first one was: “Tell me, please, how do you record drums?
