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

Non-linear hearing

For the normal average organ of hearing of a person, there are some limit (threshold) minimum values ​​of the physical parameters of the sound field, at which there is still an auditory sensation. Such a threshold of audibility is the standardized sound intensity I0 = 10 … 12 W / m2 (close to the threshold of audibility at f = 1000 Hz in silence), as well as the corresponding sound pressure p0 = 2 * 10-5 Pa and sound energy density e03 * 10-15 J / m3. The hearing threshold is private dependent. Above the threshold of hearing is the hearing area. In fig. 1 shows a curve of the threshold of audibility. The upper threshold of audibility is also shown there, above which the destruction of the organ of hearing can occur – the pain threshold, which corresponds to pressure pmax = 150 … 200 Pa, which exceeds 107 times p0 = 2 * 10-5 Pa.

Frequencies to Remember

Classically, the sound spectrum is divided into three parts: low, medium and high frequencies. The frequency limits, although not everyone agrees with this, can be defined as follows: low from 10 Hz to 200 Hz, medium from 200 Hz to 5 kHz, and from 5 kHz – high. For a more precise definition, let’s divide these three parts into smaller ones and consider them separately.

1) Low bass (from 10 Hz to 80 Hz) – these are the lowest notes from which the room resonates, and the wires begin to hum. If your sound reproducing equipment does not reproduce these frequencies, you should feel the loss of saturation and depth of sound. Naturally, when recording and mixing, the loss of these frequencies will cause the same effect.

2) Upper basses (from 80 Hz to 200 Hz) are the top notes of bass instruments and the lowest notes of Continue reading
