Re: Nyquist-Shannon
> Are you saying the music is a truly periodic signal, or that it is sampled in time from minus infinity to plus infinity or something similar? If not, how do you apply the theorem to get *perfect* reconstruction for finite non-periodic signals?
As I recollect, the periodicity only gives uniqueness of decomposition. That uniqueness may perhaps have some practical benefit, but any decomposition would still be correctly re-composed. As for the infinite duration issue, you can easily show that you get the same results (at least so far as human hearing is concerned) as by feeding an arbitrary duration of silence into the sampling process before and after the recording.
So actually it isn't bullshit in practice.
