Parametric filters
The so called ‚parametric’ filters are widely used in professional audio equipment, for
example in mixing desks or speaker processors. The curve of this filter is described
with certain parameters, mainly the centre frequency, the bandwidth and the gain
(boost/cut) of the filter. Combinations of these parameters can control the frequency
response of an acoustical system.
