Ted:When you say
an appropriately bandlimited transient can show up in any phase and be correctly reconstructed. E.g. the sampled point isn't necessarily the peak, the correct peak will be there after the reconstruction filter
You're right, but doesn't "appropriately band limited" mean containing no signals with a component at more than half the sample rate?
So a 44.1kHz stream can't contain any anything above 22.05kHz, i.e nothing with a period of less than 45uS.
If there is information in the original signal that the ear/brain can discriminate down to the 20uS range, does bandlimiting (and therefore the subsequent A/D/A) have the effect of eliminating/smoothing/smearing that information?
