Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

...whether Perl is available under CygWin?
It is. I'm currently working with cygwin. It's a reliable way to get many of the essential tools if you have to use windows. But it's a bit slow. I don't know, if it's fast enough for this program.

I can give a few pointers as I designed the bash script 'AudioScope.sh' here: AudioScope Project. to include it.
It captures using the now defunct 'SoundRecorder.exe' for Windows 8.1 OR CygWin's builtin '/dev/dsp'. Both methods take around 2 seconds total for a 1 second burst, BUT, because CygWin is _emulating_, (for want of a better description), a UNIX style environment accessing either capture mode takes around 1/8th of a second berfore the audio device activates.
SoundRecorder.exe, (which is no longer part of Windows 10), can only do a standard '.wav' file at 44100sps and /dev/dsp a '.raw' unsigned integer file at 8000sps from the command line.
The 'mintty' terminal is quite capable of all the escape codes I have used so far, including the title bar.
The above shell project was designed for hopefully ALL *NIX flavours with bash and included SoX, a dependency, as the prime mover for capture.
