Over all, the new text is non-normative, except for the phrasing "care must be
taken to discard (filter out) the high-frequency information". Here, it is said
that something must be done, without specifying what must be done.
At this point, I don't really have a preference for whether we should strive to
have a common method for synthesizing sound, or allow for variations between
implementations. However, I think it should be clear what the upper/lower
quality bound is.
For instance, if we disregard the anti-aliasing requirement, it would be
possible for an implementation to simply do an inverse FFT of the wave table as
a pre-processing step, and then do nearest neighbor interpolation into that
time-domain signal without any anti-alising or interpolation efforts at all.
Would that be acceptable?
