- * @short_description: Windowed Sinc band pass and band reject filter
- *
- * <refsect2>
- * <para>
- * Attenuates all frequencies outside (bandpass) or inside (bandreject) of a frequency
- * band. The length parameter controls the rolloff, the window parameter
- * controls rolloff and stopband attenuation. The Hamming window provides a faster rolloff but a bit
- * worse stopband attenuation, the other way around for the Blackman window.
- * </para>
- * <para>
- * This element has the advantage over the Chebyshev bandpass and bandreject filter that it has
- * a much better rolloff when using a larger kernel size and almost linear phase. The only
- * disadvantage is the much slower execution time with larger kernels.

- * <para>
- * Attenuates all frequencies above the cutoff frequency (low-pass) or all frequencies below the
- * cutoff frequency (high-pass). The length parameter controls the rolloff, the window parameter
- * controls rolloff and stopband attenuation. The Hamming window provides a faster rolloff but a bit
- * worse stopband attenuation, the other way around for the Blackman window.
- * </para>
- * <para>
- * This element has the advantage over the Chebyshev lowpass and highpass filter that it has
- * a much better rolloff when using a larger kernel size and almost linear phase. The only
- * disadvantage is the much slower execution time with larger kernels.
