saturation.
Each tunerchannelsource was sharing a thread pool and as the processing
load increased, the thread pool was not expanding and the processing
tasks were backing up, causing the buffers to grow with unprocessed
data.
Changed so that each tuner channel source is handed a thread pool to use
for processing incoming sample data. Processing chain maintains the
thread pool and starts the channel source. This allows traffic channels
to reuse the thread pool across multiple iterations.
state enumeration is designed to block these attempts which can occur
when a non-standard call sequence of events occurs, normally due to
intermittent decoding.
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.
Resolves issue in tuner controller where controller was not releasing
sourced tuner channels, preventing re-tuning to other frequencies.
Resolves issue with channel timeout on MPT1327 monitored traffic
channels
-Adds new LoJack AliasID allowing user to specify a lojack function and
5-character reply code with wildcards.
-Removes SiteID as an alias option for LoJack.
Valid Alias IDs for LoJack now are:
-LoJack Alias ID: for function and reply code combinations
-ESN ID: for transponder addresses
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
actions.
-Updated LJ1200Message to return proper address, reply code and site ID
aliases.
-Update LJDecoderState and LJDecoderPanel to properly reset after a
successful decode and to correct issues with gui label coloration.
-Improved handling of channel grants and call event logging
-Prevent traffic channels from changing to control channel state
-Change text on PDU Alternate Multi-Block to reflect trunking message
type
-Added interface for Adjacent Site messages and improved logging
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
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.
per-call recording and accurate state tracking.
Resolved issue with ThreadPoolManager limiting total number of scheduled
tasks (removed limiter - original intent is now OBE)
Updated ChannelState to better handle auxiliary decoder decode events,
so that when a fleetsync ident is at the end of the transmission, the
decode doesn't kick the channel back into a call state after it has
faded, causing static bursts and additional empty recordings.
Updated recording file name to include millisecond level precision, to
further avoid duplicate recording names
