I saw that video..... (I thought you were referring to a different video.) It was a nice demonstration, actually..... But it still doesn't address transient signals.....
Note that the digital filtering used during that demo was a classic "sinc" filtering, and the "Gibbs' phenomenon" being the ringing, which actually *is* introduced by the digital filter, since it convolves the raw digital signal with that (time-truncated or "windowed") "sinc" function.
A "time resolute" filter would "violate" Nyquist.... But many, including myself, believe it's truer to the initial analog music signal, prior to digitization. (Nyquist must be met strictly during A/D. During D/A, it's not critical.)
I thought transients were pretty much part and parcel of music. Now you are saying "digital" can only properly reproduce sine waves?
The link below certainly seems to be chock full of transients. Even filtered through YouTube I've no difficulty in hearing the dynamics and distinguishing the various instruments. How would an analog recording, of the same file size, improve upon it?
TIA
