Thanks Karl,


@Thomas: OSX is BSD under the surface so would be very suprised if there isn't a python package for it. like Python Releases for Mac OS X | Python.org

Yes I should be able to run it somehow, perhaps via Terminal. I think that there is a package pre-installed. Unfortunately I have very limited knowledge of using command-line via Terminal except for some basic commands. I used to know more, but that was a long time ago.

I've played around with Python 3.7.4 /IDLE and managed some things, but I have very little knowledge about this. Changed home dir, and inserted the name of test file to run. Appears to need/import some other modules?

from scipy import signal
ModuleNotFoundError: No module named 'scipy'

yes you will need scipy and numpy libraries, which should be a simple download.

OK thanks, I look around for that!

Just did some speed measurements on my own revised Thorens TD124 .
Included the spectrum of the two Technics SP 10 players,
