you said:
" Doesn't change the fact that you cannot generate the signal easily with NBS traceable equipment. According to your paper, you're using a CD."
You aren't really serious about this kind of stance, are you? I provided a very easy way for others to duplicate what I did with a minimum of equipment and investment. This is not a crime or a problem.
As I noted in another post here, the signal can easily be generated via a full duplex soundcard by playing back a previously constructed wave file
This is not traceable to an NBS standard.
"Doesn't change the fact that it cannot be interpreted with anything less than lots of computing horsepower."
I addressed this earlier, with regard to just how much computing power was needed.
The use of a simple Excel (or other brand of) spreadsheet allows one to hone in on as many distortion products as one wishes to check, including spcifically for HD, THD, IM, etc. Last time I heard, such a spread sheet will run on just about any computer that is still working!
What about all the computational power needed to seperate out all the products generated?
You said:
"Again, I urged you to go look at Steve Eddys comments on this at AA, have you???"
Yes, he should go look, because then he would discover that what Steve Eddy was posting about was primarily his concen over wire movement, ....
So put the Steve Eddy train to bed, it is not at all like you are trying to portray it here.
Okay, so here it is:

Please note his conclusion:
I don't see that anything is clearly shown other than crossover effects.

Even though you've submitted your paper to the AES, it has never made it past the pre-print stage, including given an opportunity to present it at a conference.
That's speaks volumes.

PS - It's too bad some moderator sees fit to delete a perfectly valid argument from a thread that is already closed, requiring this action to replace it.
