Yes that is correct.........but one needs to make sure the sound card calibration is correct.
By the WWV method, I can get the (out of phase) WOW to about 1 every four or five seconds; pretty durned close (enough).
With the software approach, any sound card error (which can vary a lot) is corrected so any software using it, is dead on.
Bottom line is that unless you're attempting the ARRL FMT, a few hertz won't be noticed by most; aging ears just aren't that good a test and most software isn't that critical either.
