Hi all...

Well a lot has been going on behind the scenes here.

The latest Quicktime Player access for Sierra is now broken as of OSX 10.12.2. It works in 10.12.0 and 10.12.1 but is now broken again. <SIGH>
I am now abandoning Quicktime Player as a hidden capture mode. The code will be left in just in case a newer version of OSX works again, but I suspect Quicktime _Whatever_ will be phased out completely so I am chasing it no more.

I have done some major changes to allow for a seriously slow CygWin(64) running in the latest Windows 10. As quoted before Windows 10 no longer has SoundRecorder.exe so I am abandoning WINSOUND capture mode but leaving the code in for CygWin on Windows 8.1 and lower.

There is now a small, cyan, sub-window inside the main scanning window to display any DC component when enabled. In AC mode it will always show 0.000 Volts.

Although AC mode is now long since finished there is lots to do for DC mode.

As CygWin does NOT have the 'bc' or 'dc' commands on a standard install then 'awk' will have to do my floating point calculations for any average DC values on any random signal sent up the mic socket.

Stats so far for this Version 06060...

# Total Lines=4509.
# Blank Lines=30.
# Code Lines=2122.
# Comments=2357, (including the builtin Manual).
# Filesize=193247 bytes.

Because CygWin is so slow on Windows 10 I have to modify '/dev/dsp' capture timings due to OS time lags.

Boy oh boy the things I have learnt about OSes and their limitations is unreal.

A certain Linux flavour does not like the ZOOM facility, but hopefully this is now cured.

All needed files for the whole project are now saved to a new "$HOME"/Temp/ drawer. /tmp/ is no longer used.
These are saved to "$HOME" only:-
AudioScope.sh
AudioScope.config
AudioScope.Manual

Hopefully there are no critical bugs in 'DEMO', '/dev/dsp' and SOX modes.

Enjoy...

Boy oh boy, with only a MONO mic input to use AudioScope gets much more difficult when the ALTDC board is included.
