Band Filter
The Band Filter lets you hear a certain band of frequencies within an upper and lower range. Frequencies above and below this band are attenuated. The distance between the higher and lower cutoff frequencies in a band pass filter is called the bandwidth of the filter. The center frequency of a band pass filter is the maximum point of amplitude.
In the Properties Window you can change the effect properties. It's possible to select the necessary preset from the dropdown list or choose the filter type and set custom values for Frequency and Steepness manually. In the Type dropdownlist you'll find a lot of filters, to read more about them click here.
