USB cable - YouTube shows differences

This is a great video using interesting method to show differences in USB cables. Uses inverse of usb single to see if it cancels out vs original file. It’s one year old so forgive me if you have seen already.

Just saw your post. Great video. I have zero technical competence in these matters but I thought to myself that it would be cool to do some work on interconnects, speaker wires and even power cords via A to D conversion. Not that this would be a means to determine which possible cable might be better or worse but to demonstrate to folks that there are meaningful differences that don’t just show up in capacitance and inductance curves. I dunno: just a thought.
