Again, *why*? If you can compile these programs in the Cygwin Terminal, you can run them there, too.

The asterisks (*) are a form of emphasis, created in the days before you could send italics and bold text formatting over email.
“Box” is a slang term for computer.

That explains nothing. You can build programs with “make” using any compiler. It is not Cygwin-specific.

I can’t help you there. You’d need to examine the contents of the wave files and compare that to the known behavior of the algorithm.
A waveform editor like Audacity may help, but that’s way off topic here.
Brian is right: this set of programs is far from the best way to achieve your purpose.
