"Of course they are. At the mathematical, signal theory level both increase the samplerate and apply brickwall filtering at the original fs/2."At least you have that part right... unlike the author of the white paper referenced at the start of this thread...
I think the problem is maybe people like the author *hope* the "advancement" in technology is truly an advancent, and since the "science" behind the "advancement" seems to be vague (because it happens to be bogus), they **speculate** on what the science might be behind the advancement. While not being up to speed on the basics of digital theory. This is why there has been a plethora of articles with bogus information on the upsampling subject. (And the bogus points amongst these articles often contradict each other.)
I am only here to keep the record straight in regard to the facts and myths of upsampling. I think everybody wants to see advancements in technology, and purchase such products. But the hard part is separating the fluff from the real breakthroughs. For a lot of products out there with this purported "new technology" ain't cheap, and I see a lot of regret from people after purchasing such products, and come to the reality the "new technology" is actually the same old tired technology spray-painted over with the latest technological "buzzwords."
