Graphic equalizer is a multi-range corrector of the amplitude-frequency characteristics of electric sound signals. The boundaries of the full range of frequencies in which the amplitude-frequency characteristic is corrected are determined by the range of frequencies perceived by the human ear. The lower limit of this range is sound vibrations with a frequency of 20 Hz. (oscillations per second), and the upper – 20 KHz. (thousand oscillations per second).
The graphic equalizer, depending on its accuracy, determined by the width of one band, may contain a different number of ranges in which the values of the amplitude-frequency characteristics are set. For example, with a bandwidth of one octave, the equalizer will contain 10 bands, with a bandwidth of 1/2 octaves – 15 bands, and Continue reading
