Changes to model, view and controller components and updates all gui
editors. Removes the configuration panel and tree and replaces with 3
new panels. Updates playlist.xml to a new playlist_v2.xml format.
Removed frequency change listener framework from tuner so that the tuner
controller handles all frequency change interaction.
Updated tuner view to allow selecting tuners for main spectral display
and/or launching a new spectral display by clicking in the tuner table
cell.
configuration and tuner configuration assignment editors. Beginning of
tuner editor panel rework. Removes most of the remaining JTree
configuration pieces. Updates the settings manager to load and save
tuners and refactors all of the tuner configuration management out into
the tuner configuration model.
number of unused classes. Removed playlist manager from a number of
classes and replaced with the alias, channel and channel map models.
Updated playlist manager to no longer retain a playlist except for when
loading to models or when storing from models. Extracted version 1 to
version 2 playlist conversion and changed playlist manager to keep the
original version 1 playlist and create a new version 2 (playlist_v2.xml)
file. On startup, try to load a v2, and if not, look for a v1 to
convert. Otherwise, don't create a playlist and one will be created
once the user adds items to the models.
the spectral display to be slow to reflect changes to tuner settings.
Changed the max size of the sample queue based on the highest rate tuner
sample rate 10 MHz (airspy) and the lowest available spectral update
frame rate (12). Sized the buffer queue based on the maximum number of
buffers that should be available per DFT processing iteration. If the
queue backs up, new buffers will be discarded until the DFT processor
consumes the queue and catches up.
-Started work on new channel editor channel viewer/controller
-Removed a number of unused buffer package classes
-Moved automatic frequency control to be a module and removed special
handling
-Added IUnfilteredRealBufferListener & Provider interfaces
-Completely removed the ResourceManager class
specifically for P25 C4FM frequency tracking.
-Clarifies frequency change event naming and adds request/notitification
events for channel frequency correction type events
-Removes DC offset filter from P25 C4FM demodulator which was operating
independently of the AFC tracking component within the C4FM symbol
filter.
-Changed FCD tuner center DC spike buffer size after detecting that the
DC center spike was influencing the P25 C4FM filter frequency tracker
whenever the tuner's center frequency was changed to bring the channel
boundary within 3 kHz of the center spike -- set it to 5 kHz to provide
a better buffer.
-Updated spectral channel display to provide better indication of
automatic frequency control (yellow line) versus channel frequency
calculation when additional channels are allocated.
Incorporates tuner specific definition of overall usable bandwidth, so
that tuners like airspy can specify 90% of 10 MHz (ie 9 MHz) is truly
usable and the fringe 10% is unusable rolloff.
Also includes tuner-specific defining of the width of the central spike,
or a value of 0 indicates that the entire range is usable (ie airspy).
overlay.
Minor edits to MPT and P25 config editors
Resolved issue with channels not accepting channel config changes
between restarts (processing chain was not being deleted)
Minor edits to P25 decoder state
Adds Spectral/Waterfall display zoom feature with mouse dragging and
zoom window indicator.
Resolves issues with correct display and spacing of frequency labels and
tick lines display in the overlay panel.
Resolves issue with tuning RTL2832 based tuners into the range of
799.555894 and 801.584395. The pre-defined sample rates were slightly
off and causing issues with this tuning range. I recalculated the
sample rates and removed any that were not integral multiples of the
48,000 Hz desired channel rate.
Updated the sample bit depth for RTL2832 and HackRF tuners. Even though
the sample bit depth is 8 bits for each, the displayed noise floor was
off, so I increased the bit depth for each.
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.
from Module so that Decoder can function independent of DecoderSTate and
DecoderState can more cleanly interface with other modules.
Resolves issue with LTR-type decoders where the AudioModule was
filtering demodulated audio buffers before the decoder received the
audio - demodulated audio buffers are now copied before creating
AudioPackets.
Note: Several of the decoders are currently non-functioning in this
commit. If you want the latest functioning codebase, please checkout
the commit prior to this one. All decoders will eventually be updated
with this new architecture.
Currently broken:
- Logging and recording
- Aux decoders (Fleetsync/MDC/LoJack/Tait)
- LTR/Passport decoders
Changes in this commit:
- Module architecture for decoders and components with central
provisioning by the DecoderFactory
- Transition from Complex sample stream processing to float buffer
processing for improved memory management
- Redesigned filter structures - to support buffers and streams
- Resolved several memory leak issues
- Universal sharing of the thread pool manager
- Added centralized audio management with call/user prioritization and
new gui with mute/volume controls
- Embedded audio metadata for eventual streaming support
- Redesigned ProcessingChain to support independent re-use
- Added new TrafficChannelManager to handle traffic channel allocations
- Traffic Channel pool size and Call timeout available in P25 and
MPT1327 configs
- Redesigned channel and decoder gui components
Changed C4FM symbol filter to reset frequency tracking values when the tuner's frequency or PPM values change.
Moved all frequency control pieces into the source.tuner.frequency package.
Memory Fixes
Decreased the decimation process repeat timing so that it runs smaller work chunks more often
Decreased scheduled thread pool to 2 hot threads
Wrapped all scheduled thread pool runnables in try/catch blocks so that an exception doesn't kill the sample buffer processing thread and cause the buffer to grow unbounded.
P25 updates
Moved TSBK crc checks into the message framer so that message corrections don't occur after the message is constructed.
Added more functionality to the channel state for handling registrations and call events.
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.
