Charles J. Cliffe 0e2984ab18 Merge pull request #8 from cjcliffe/dynamic_demod
Dynamic demod, x86-64 switch and std::thread
2014-11-22 23:15:19 -05:00
Charles J. Cliffe fa521ac30d Switch from portaudio callback to stream write
It’s already in a thread, not sure if callback was helping?

Charles J. Cliffe 99aa87df63 Now working on gcc4.8, x86-64 on windows
Had to make my own portaudio and rtl-sdr binaries. The available
packages weren't compatible somehow.  Also wxWidgets wxPack doesn't
include OpenGL support but it's easy enough to compile.

Charles J. Cliffe 6624ec11a3 IQ->Demod->Audio threads now chained
No longer passing anything through the main thread which was causing
audio and IQ interrupts on UI events -- hopefully improves OSX jitter.

SDRThread can now have unlimited Demodulator bindings.. :)

Charles J. Cliffe 739854cd7f Demodulator and Audio threads working
Data now flows from SDR IQ Thread -> Demodulator Thread -> Audio Thread.
Seems to have added a significant audio delay though..

Charles J. Cliffe 810533750f waterfall optimize, fm demod audio filtering
Moved waterfall increment into rendering to reduce audio processing
impact.

Added another test filter and resample stage to FM demod experiment to
clean up audio and remove high pitch on stereo channels until it can be
demodulated.
