The center frequency is specified in Hertz. Sound characters of the different frequencies are best discovered through experimentation. The bandwidth may be specified in octave bands. One octave band equals the frequency range of one octave on the piano keyboard. The bandwidth is the same parameter as the Q-factor found in some analog equipment. A higher Q-factor represents a narrower bandwidth.
Equalizer terminology
The lower part of the equalizer dialog box is used to display the filter response curve (gain versus frequency). The filter response curve is calculated mathematically and is updated as the parameters are altered.
The Equalizer settings

| The frequency response of the current equalizer settings is visualized. Each band is visualized with a small circle with the number of the band. The currently active band is highlighted. You can activate band by clicking the circles representing each band. If you keep the mouse button down while moving the mouse cursor, you can change the gain and the center frequency of each band directly in the frequency response.
