How To Fix zita-lrx: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu zita-lrx is provided by zita-lrx package.

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). Outputs are exactly phase matched in the crossover regions.

The application supports up to 16 channels.

Configuration is by a text file using ‘OSC’ style syntax (similar to Ambdec and Jconvolver). Apart from the basic filter parameters, the following can be set:
