Updated p25 decoder state to better track calls and call detects from
a trunked channel
Fixed issue with false detects on LDU2 encrypted call messages
Fixed Airspy channel allocation ... will allocate channels across the
entire bandwidth, minus 50 kHz on either end, and will not adjust the
center frequency if it's not needed.
Fixed traffic channel teardown -- traffic channels are immediately
removed now, without a fade delay.
AudioMetadata - updated flag is now reset upon copying the metadata
component.
-Airspy supported with 10 and 2.5 MSps sample rates. Additional
decimation may be added later.
-Spectral display updated to include smoothing and filtering options.
Note: the decimated output of a tuner channel from the airspy is
48,076.9 samples per second, versus the normal 48 kHz decimated rate.
This is 1.0015 times the normal rate and doesn't appear to impact the
decoders or audio processing. Therefore, no fractional resampling has
been added.
- Adds Channel Spectrum tab to display FFT of the audio output of the currently selected channel
- Upgrades to JTransforms 3.0 FFT library
- Adds three new context menus to main and channel spectral displays:
-- Baseline - affects the vertical rendering baseline of the FFT
-- Amplification - affects the vertical height of each FFT bin
-- Averaging - affects how many FFTs are averaged to produce the display
NOTE: only the gui components and settings handling have been implemented. Actual recording playback is not yet implemented.
Partial checkin of initial P25 decoder development.
NOTE: P25 decoder is not yet functional.
