By increasing the Q to 10.000, the center frequency remains the same. The markers show
the bandwidth of the filter narrowed to between 900 Hz and 1200 Hz, or about 300 Hz
(see figure 29). Using the Q value, parametric filters can be used to notch out a very
narrow, or very wide range of frequencies.

The dialog box above shows the frequency curve for a single active filter. To add its effect
