Except the problem of time machines: When interpolating around a non-delayed
signal, you are interpolating around the time "now" and so you would need
at least one sample from the future, whhich hasn't happened yet.

This is not only valid for the "first" sample, as in a constantly updating
delay line there is no "first sample".
