 ::  Graphic Equalizer

Equalization is a process of normalizing the frequency response to be as flat as possible to reflect the original reproduction of the sound. Equalization is necessary for several closed environments, where reflections or speaker limitations influence sound quality. With the ability to both boost and cut several frequency bands, it is possible to neutralize external factors for a natural sounding audio.

The equalizer can also be used to simulate a music type which is rich in specific components. The several presets available with the Graphic equalizer serve this purpose.
