Charles J. Cliffe fe2e56231d gradient util, started waterfall implementation 2014-11-11 08:11:12 -05:00
Charles J. Cliffe b270379361 Honor PA_RECOMMENDED_OUTPUT_DEVICE on Win32 
PortAudio defaults to output on my Virtual Cable INPUT #A?? -- strange
but this gets around it neatly for now.

Charles J. Cliffe 9913629a7e Use first available RTL device 2014-11-09 20:55:21 -05:00
Charles J. Cliffe a78a862cba Moved demodulation code into it's own class 
Preparing to make it more dynamic, able to tune multiple frequencies at
once and support remaining demodulation modes (AM, USB, LSB)

Charles J. Cliffe 14d7e431bd PortAudio adjustments for OSX 
Seems to be some sort of audio init race condition, intermittent crash
on startup

Charles J. Cliffe b70b659a5f Removed OpenAL and now using PortAudio 2014-11-09 04:38:33 -05:00
Charles J. Cliffe c3c204bc04 Pitch issue fixed, OpenAL weirdness 
Might be time to retire OpenAL -- is behaving strangely on output
stream..
