About the history of sound recording
Today, the main recording methods include:
– mechanical
– magnetic
– optical and magneto-optical sound recording
– solid state flash memory recording
Attempts to create devices that could reproduce sounds were made in ancient Greece. In the IV-II centuries BC e. there were theaters of self-propelled figures – androids. The movements of some of them were accompanied by mechanically extracted sounds, folding in a melody.
In the Renaissance, a number of different mechanical musical instruments were created that reproduce a particular melody at the right time: barrel organ, music boxes, boxes, snuff boxes. Continue reading
MIDI keyboard
We all know synthesizers, which are “electronic pianos” with many special effects and functions.
The whole charm of the synthesizer lies in the fact that it can autonomously act as a musical instrument, providing good sound from almost any timbre.
There are also disadvantages, the main of which is the relatively high cost of a good synthesizer and its significant dimensions.
The MIDI keyboard is deprived of this minus. it costs less and extensibility is better …
MIDI keyboards are, in fact, simplified versions of synthesizers that do not have built-in sounds, additional functions and effects.
In this case, the functionality and implementation of special effects is assigned to a personal computer. Continue reading
Equalizer
Equalizer (English equalize – “equalize”, the general abbreviation is “EQ”), a timbre block is a device or computer program that allows you to increase or decrease the volume of individual zones of the frequency range, equalize the amplitude-frequency characteristic of the sound signal, that is, adjust it (signal) amplitude selectively, depending on frequency.
Born in the 30s, the equalizer is the oldest and most commonly used sound processing by sound engineers. Today, the market lacks a variety of instruments for timbre correction – from a simple bass-treble corrector of the 50s to a sophisticated multi-band equalizer with perfect parameters. At its core, the equalizer is a few electronic filters that allow you to change the amplitude-frequency response of a sound device. Over the past half century, the equalizer circuitry has improved tremendously, trying to satisfy the increased demands of the audio industry. Continue reading
