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 29). Using the Q value, parametric filters can be used to notch out a very
narrow, or very wide range of frequencies.
Figure 29. Parametric Filter at 1000 Hz, Q: 10.000
The dialog box above 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 by clicking
Bypass.
