fa521ac30d Switch from portaudio callback to stream write 
It’s already in a thread, not sure if callback was helping?

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.

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.. :)

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.
