d466ec9f5e Changes audio module decimation filter from lowpass to bandpass so that we can remove 0-250 Hz and any LTR signalling from the audio output. 2016-08-21 07:21:38 -04:00

3af4b953f4 Changes internal audio sample rate from 48 kHz down to 8 kHz. Updates the P25 audio module to output 8 kHz audio. Updates the audio recorder to record at 8 kHz rate.
Note: required updated JMBE 0.3.3 library which supports 8 kHz audio output sample rate.

a56935f92c Closes #74 - adds support for vendor-specific (Motorola) TSBK patch group management. Processes patch group channel grants and updates and allocates voice channel processing. Logs call events for patch group add (register) and patch group delete (deregister). Also adds call event logging when there is a planned control channel shutdown--logged only once. 2016-07-31 07:52:01 -04:00

218eeb1848 WIP #34 - more work on tuner model and view. Includes new tuner
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.

2394ac2fa9 WIP #34: added channel map manager and new editor window. Removed a
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.

f7f6c2fc3e Merges changes from master branch to resolve issue with CPU and memory
and constraints on scheduled thread pool saturation.  Adds a new
scheduled thread pool for each processing chain that the components in
the chain can share, versus the single shared pool exposed by the
threadpoolmanager class.

8db226cd7b Adds broadcasting of unknown P25 message types. If a P25 message passes
the NID crc check but uses an unrecognized data unit id, it will now be
broadcast as NID:UNKN, but allows for detection of new DUID types when
we have a large number of occurances of unknonwn duid types.

e7d3713791 Removes message broadcaster from Decoder abstract class -- processing
chain has a message broadcaster built in, so the decoder's broadcaster
is redundant.  Changes Decoder(s) to only have a single registered
message listener (ie processing chain)

ddfefe4b85 Resolves issue with ChannelState FADE monitor - changes from
starting/stopping the monitor for each call to simply leaving the
monitor task running continuously.  Was causing issue with scheduled
thread executor not shutting down the task in a timely manner -- new
approach should avoid start/stop related issues altogether.

Updates P25DecoderState with reordering of timing of when we send
updates for the TO/FROM identifiers so that the audio manager receives
up-to-date metadata and hopefully resolves issue with 'Do Not Monitor'
talkgroups being monitored by the audio manager.

Updates the AudioManager with a try/catch block around the processing
task so that we can catch any audio processing exceptions that occur
during the timer task and might get suppressed by the scheduled thread
executor.

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
