**zita-lrx**  is command line jack application providing 2, 3, or 4-band, 4th order crossover filters. The filter type is continuously variable between Linkwitz-Riley (-6dB at the xover frequency) and Butterworth (-3 dB at the xover frequency).

Apart from the basic filter parameters, the following can be set:

  \- Channel labels (used for naming Jack ports).

  \- Frequency band names (used in output port names).

  \- Optional output autoconnections.

  \- For each channel: gain and delay (in ms).
