FCL splits wideband spectrum from your SDR into narrowband channels.
This is useful for networks that have lots of transmitters side-by-side,
like for example FM broadcast, TETRA, Tetrapol and GSM.

It supports everything you would expect from a decent channelizer:

* Channelization
* Oversampling and overlapping channels.
* On-the-fly frequency correction and signal power detection.
* Multiple input formats (float, unsigned and signed integer).
* Multithreading.
