>>Hey Tony, in case you forgot, the goal of the digital signal in question was to recreate two cycles of a 20KHz sine wave
That is NOT a band-limited signal, and can NOT be correctly recreated by a system sampling at 44.1. Not NOS, not upsampled. Never. Until and unless you understand the very important implications of that, further discussion is completely meaningless. Bickering about filters etc is completely meaningless if you violate the basic primary assumption of sampling theory. THAT is why Tony correctly pointed you at signal theory references.
This is probably the millionth time someone has advanced this argument on this forum. It was wrong the first time. It's wrong now. It'll be wrong next month when someone else tries it again.
