...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.
