A compressor is a device that allows you to smooth out the dynamic range of a signal. In simpler terms: what was quiet will become louder, and what was loud will become somewhat quieter. As a result, the sound will become more dense. In addition, the compressor allows you to even out technical recording defects: for example, when recording vocals, vocalists (especially not experienced ones) shake their heads, swing the microphone back and forth, periodically bounce, kick their feet and do other funny tricks, which leads to a floating volume level. In this (and in many other situations) a compressor will help, which will smooth out the level change. Continue reading
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
PHYSICAL BASIS OF SOUND
The word “sound” defines two concepts: the first is sound as a physical phenomenon; the second is sound as sensation.
1) During the vibration of an elastic body, such as a string, in the air surrounding it, pressure fluctuations occur, which propagate in space due to the elastic properties of the air.
These vibrations are called sound waves. They propagate from the sound source in all directions (that is, Continue reading
