405 Airspy Spectrum/Waterfall Freezes

43fc326f93 Resolves #405
Adds 500 ms delay to initial registering for samples from all tuners to
feed the spectral display/waterfall.  The existing approach of immediately
registering for samples was causing the airspy tuner to lockup
aperiodically.  Investigation via debugger didn't show any application
thread locks ... usb master processor was continuing to service libusb
timeouts.  Unable to debug internal airspy processes.  Adding the delay
to startup seems to be a usable solution.

375 P25 Decode Performance

96a56cab68 Resolves #375.
Reverts PLL gain values to version 0.3.4beta2 values to restore P25
decoder performance.

This change in conjuction with recent channel sample rate change should
restore P25 channel decoding to comparable levels from 0.3.4b2.

b15a3e59a0 Resolves #411
Updates decoder types to specify channel sample rate and pass/stop
frequencies for requested channels.  Updates tuner channel source
managers to accept a channel specification for channels that are
allocated.

406 Tuner Sample Delay Buffer
2018-09-09 08:47:17 -04:00
Denny
570321da3e Implements a complex sample delay buffer integrated into the tuner
channel manager so that channel source requests can have a start
timestamp specified and the channel can be preloaded with samples from
the delay buffer.  If no timestamp is specified, current time is assumed.

This feature requires corresponding updates to any decoder that wishes
to implement the timestamped sample preloading functionality.

8946d789ff WIP - updated tuners to use CIC decimation tuner channel sources instead
of polyphase channelizer.

Channel sample rate reduced to 30 kHz - seems to work better with P25
decoders than previous 25 kHz.

ade0cef50b Updates P25 C4FM and LSM decoders to provide demodulated bit streams
for recording using the new binary recorders/format.
2018-08-18 03:36:17 -04:00
Denny
2044c2a2de WIP - Updated P25 C4FM and LSM decoders to assemble dibits and push
reusable byte buffers out to the processing chain.  This enables the
processing chain to broadcast these buffers back to the decoder for
message assembly and to any running binary recorder.

Updated P25Decoder to be a reusable byte buffer listener.  The decoder
will now pass reusable byte buffers down to the message framer for
message processing.  This should make the code more efficient since it
can process byte arrays versus handling each individual dibit.

The P25MessageFramer has been updated to be a listener of reusable byte
buffers instead of Dibits, but the actual processing of byte arrays
has to be coded.

Added max recording size to the binary recorder so that it cycles at
500 kB max file size.

5f8f2ec330 Resolves #393 - Adds support for recording demodulated (raw) bitstream
buffers.  None of the decoders currently support this yet, but the P25
will be updated to provide bitstream output for recording.

Renames the ReusableBuffer class to ReusableFloatBuffer for
consistency.

389 Add ACTIVE Channel State and Update P25 Decoder State processing
2018-08-11 05:39:20 -04:00
Denny
8e4e4129ca Adds 'ACTIVE' as a valid channel state to indicate that the channel is
actively decoding, but no call or data is being transmitted.  This is
primarily used for P25 channels when TDU Link Control messages are
being transmitted in between voice or data transmissions on a channel.

Updated several of the P25 decoder state message processing sections to
keep the channel state UI updated with current call identifiers and
states.

Hard-coded channel state colors to remove inefficiency in the way that
channel state coloration was being handled.

a3e5520d3e Resolves #372 - Icecast reconnect following network outage. Updates
the lost connection timeout from default of 60 seconds down to 5 seconds
so that the connection state updates more quickly.  Removed complex
error handling and replaced with a simpler approach to catch an error
and disconnect and then attempt a reconnect.

Added new 'Network Unavailable' error state that detects when the network
connection is unavaialable.

Updated the icecast metadata updater to close the TCP session after
successfully writing metadata to the socket.
