OK, AudioScope.sh is now at Version 0.50.20...

There are things that are now broken due to OS changes over the years.
I am NOT going to chase these as the code IS licenced as CC0 and you can do it for yourselves.
These are the ones I know about.

1) As of Windows 10, 'SoundRecorder.exe' no longer exists and is now called 'Voice Recorder'. I have
no idea if it can run in the background as I do NOT intend to take CygWin(64) any further. So consider
WINSOUND capture unavailable beyond Windows 8.1. CygWin(64) still has /dev/dsp so that is the ONLY real
capture mode available. SOX in CygWin(64) is not, and has never been, catered for.

2) 'xterm' is now deeply hidden inside OSX 10.11.x and is not in the path when called, this also
applies to some current Linux flavours and requires an xterm install for correct running of the code.
I do not intend to check for availablity as usually a second computer is required for calibration due
to crosstalk using the same computer for both Input and Output down the same socket.

3) QuickTime Player is broken as of OSX 10.10.x and above so OSX107MBP background capture mode is no
longer available. I have tried to solve it but cannot get it to work. ;o(

There are still changes to do to the script to remove old legacy stuff and use current techniques and
they will be changed in due course.

There are 24 files including AudioScope.sh itself created during program run. Most are not used in normal
running but are needed for calibration and test purposes, these are the files and their sizes, extracted
from the AudioScope.Manual...

Code:

#
# "signed16bit.txt" will only be FULLY generated in "CygWin" mode using Windows
# "SoundRecorder.exe" in quiet mode, otherwise one byte in size.
# (See Preface:- for more information.)
#
# These are all of the current files generated for the AudioScope.sh project.
# They are needed in conjunction with home built calibration hardware to
# calibrate this project. AudioScope.sh itself MUST always be in your
# "$HOME" drawer\directory\folder.

The stats for the script so far:-

# Total Lines=4253.
# Blank Lines=29.
# Code Lines=1989.
# Comments=2235, (including the builtin Manual).
# Filesize=180552 bytes.

Enjoy thinking and doing things for yourselves instead of adapting existing technology.

As usual if you download the file, place it in your $HOME darwer and rename to AudioScope.sh, and change your permissions.
