Zita-lrx  - First release 05/01/2012
------------------------------------

Zita-lrx is a 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. This is a compile time
limit and easily changed, but if you have many channels it may be
a better idea to use two or more instances in order to spread the
load in an SMP system. Not that it would matter much - on my old
2 GHz P4, CPU load is around 0.6% per channel for four bands.

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:

- 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).
- For each frequency band: gain and delay.
