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
In recent years, technologies in the field of creating spatio-temporal effects have improved significantly, and we can talk about significant progress in this area. We owe this progress to scientific research in the field of acoustics and psychoacoustics, the development of new methods for synthesizing sound space and new reverb algorithms.
Reverb (from the Latin word re-verberatus, “re-strike”) is the process of continuing sounding after the end of a sound pulse or oscillation, due to reflections of sound waves from surfaces. Therefore, reverberation takes place only in enclosed spaces, although under special conditions some of its types can also occur in half-open space (for example, in a stadium, city square, narrow mountain gorge, etc.). We can justifiably attribute to indoor spaces such a natural formation as a cave – that’s where the reverb is so reverb! Continue reading
This article discusses the principles of operation of various devices designed for sound processing.
About how and in which cases it is correct and it is necessary to use them we will discuss further.
The effects considered in the article are divided into the following categories:
Time transformations: delay, echo, reverb, various delays using modulation (phaser, frequency modulation, chorus, flanger).
Frequency Conversion: various types of equalizers.
Amplitude transformations: compressor (limiter, maximizer), expander, amplitude modulation (ripper).
Other conversions: vocoder.
Delay and Echo Continue reading
