Performs filtering, using an FFT to do a FIR filter. rief An Effect that modifies volume in different frequency bands. Martyn Shaw (FIR filters, response curve, graphic EQ) This can make setting the value you want easier. The sliders can also be made taller by resizing the dialog. Holding down Shift then either dragging the slider handle or using the arrow keys to increment by 0.1 dB.Using the arrow keys on the keyboard to increment by 1 dB.Clicking above or below the slider to jump to a nearby whole dB value.Clicking above or below the slider to increment it up or down by a fixed value in whole dB.

You can get to an exact slider value but the method depends to some extent on your operating system. Click and drag the slider up or down to increase or decrease the volume by a maximum of 20 dB. Each slider adjusts the gain of a specific range of frequencies, the gain being maximized at (centered on) the frequency stated on the slider. Frequency Sliders: the equalization curve is drawn by manipulating a set of sliders.
