WSJT-X/soundin_1.h
Joe Taylor 4e8a3f54c9 1. Refactoring of code so as to move audio input from a separate thread to
the main GUI thread (thanks to G4WJS).

2.. Also, for the record, some example code for using QAudioInput instead 
of PortAudio.  This code is not presently active, and will need to be 
changed to accommodate the changes in #1, above.  But the basic ideas 
are here...
