Re: You say: Granted for general Fourier analysis....

"WHY do you keep insisting otherwise? WHY?"

Because if one asked 100 DSP engineers, "How does the 'sinc' function apply to digital audio?", I'm sure 99 of them would answer it in the context of the sinc function as in the impulse response (time domain) of a classic digital filter, and/or the coefficient depiction used to convolve with the signal off the media. (A digital filter convolving the raw signal with the filter's impulse response.)

The other context (frequency) is trivial, unless one was fixated on the exact function of the frequency response for unfiltered playback. Maybe useful as a math problem, but otherwise a phenomenon where in the real world, the existence of the rolloff is of much greater concern than the specific function of the rolloff. (Until Werner brought this up a couple years ago, I didn't even realize it was a "sinc" function. I initially thought he had the time and frequency domains mixed up.) And a rolloff that would be remedied by the very filter mentioned in the more-common context.
