About mechanical sound recording
A mechanical sound recording is based on cutting (or extruding) grooves in the material of a recording medium using a sound recording device — a recorder. When playing along the…

Sound Perception and Compression
Traditional lossless compression methods (Huffman, LZW, etc.) are usually poorly applied to compressing audio information (for the same reasons as when compressing visual information). Some lossy compression methods are listed…

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.

About musical performance

Performance as a special type of artistic activity does not exist in all arts. In painting
for example, it is inseparable from creativity: to create a picture is what it means to “fulfill” it. Once in music, the creation and performance of a work did not separate from each other: in ancient times, a musician sang or played what he composed, improvised.

But the creation of a painter or sculptor is embodied in material that has been preserved for centuries, and the material of music (sound) lives while it sounds. Unsound, a piece of music ceases to really exist, disappears. To hear it again, it needs to be revived each time again, to make it sound again. The ability to Continue reading
