Converted to use float primitives and to keep samples in buffer format until the sample rate is decimated to 48kHz.
Added new non-recursive, CIC decimation filter -- untested
Updated sound card/mixer input source management. Now testing for mono/stereo support for each card and limiting channel choices accordingly. Separated the mixersource into a ComplexMixer and and SimplexMixerSource. The ComplexMixer is used for sound card based tuners like the funcube. The SimplexMixerSource is used for demodulated sound card inputs.
Interfaces for sample handling - standardized on using 'Complex' to indicate I/Q samples and 'Simplex' to indicate demodulated float samples. The processing chain now accepts either a decimated (48k) list of complex samples from a tuner channel source, or a 48k simplex buffer (array of demodulated float samples).
Resolved issue with HackRF tuner not applying tuner configuration information.
- Call events now show start-stop timestamps. (or START-In Progress if call is ongoing )
- Call start/stop events are now on the same event line.
- Channel panels now display site and/or channel info
- LTR call events are limited to CALLs on the current LCN, in order to cut down on false call events resulting from noise.
- Passport display channels now show site/channel.
- Changed default window used by the DFTProcessor to Cosine, which doesn't have as much FFT bin leakage.
