By increasing the Q to 10.000, the center frequency remains the same. The markers show
the bandwidth of the filter narrowed to between 900Hz and 1200Hz, or about 300Hz
(see figure 31). Parametric filters can be used to notch out a very narrow, or very wide
range of frequencies using the Q.

The above dialog box shows the frequency curve for a single active filter. To add its effect
to the overall frequency response, remove the bypass on the other filters.
