* @short_description: Generic audio FIR filter
*
* <refsect2>
* <para>
* audiofirfilter implements a generic audio <ulink url="http://en.wikipedia.org/wiki/Finite_impulse_response">FIR filter</ulink>. Before usage the
* "kernel" property has to be set to the filter kernel that should be
* used and the "latency" property has to be set to the latency (in samples)
* that is introduced by the filter kernel. Setting a latency of n samples
* will lead to the first n samples being dropped from the output and
* n samples added to the end.
* </para>
* <para>
* The filter kernel describes the impulse response of the filter. To
* calculate the frequency response of the filter you have to calculate
* the Fourier Transform of the impulse response.
* </para>
* <para>
* To change the filter kernel whenever the sampling rate changes the
* "rate-changed" signal can be used. This should be done for most
* FIR filters as they're depending on the sampling rate.
* </para>
