4be63d4b95 Work in progress.
-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

9c305b0732 Resolves issue with AFC and frequency change event handling,
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

dc3bcfd404 Resolves issue with spectral and waterfall alignment with frequency
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

e27ca12ec8 Closes Issue #33.
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.

7455077cfa Spectrum/Waterfall display zoom feature - work in progress (issue #33)
Implements zoom in/out by mouse scroll wheel and by right-click context
menu.

Still have to add ability to drag spectrum left/right when zoomed in.

f4d8ea281d Initial commit of redesigned internal processing and audio management.
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

bc5080aa4a P25 - updated automatic and direct frequency control to cleanup the code and allow P25 to better track frequency and PPM changes in the tuner and provide a cleaner implementation of the AFC component in the processing chain of all of the other decoders.
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.

8d60397547 Updated spectral display to work with any sample rate and screen dimension combination. Added ability to change channel display on the spectral display to ALL, ENABLED, or NONE. 2014-10-20 23:07:07 +00:00

550aed79d4 Changed FrequencyChangeListener interface to an event so that I could describe what event was causing the frequency change and to broadcast frequency and sample rate error values.
R820T - added a couple more sample rate settings to the enum and modified the periodic sample rate info logger.

0f43c7ed22 Automatic Frequency Control enhancement. Provides default AFC and ability to disable in the Decoder tab of each channel. Spectral display includes visual indicators of frequency center (grey) and current AFC offset (yellow). 2014-09-11 22:46:05 +00:00

4e0fd9b7b0 Channel Spectral Display
- 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

35a2cebe03 Converted frequency to long primitive type (from integer) in anticipation of HackRF support which requires frequencies greater than 2.147 GHz, which is the max hertz value that can be represented by an integer primitive. 2014-07-08 14:40:11 +00:00
