That's really why I ask - I think. If there's more than one way to
downsample properly, I'm stuffed.

In principle 'downsampling' should be done 'properly' and will then
lead to a uniquely defined results - even if done in various
algorithmic ways.

That's not so.

If you are defining "uniquely defined" as being some precise bit
pattern, then I am forced to agree.

The problem arises when the poster snips away a following comment and
ignores the distinction I made quite clearly. But which apparently escaped
his grasp. :-)


If computational resources are highly estensible, it is possible to
product digital filters with very nearly ideal phase and amplitude
characteristics.

Indeed. That is a matter of how much care, effort, and computation time,
the people involved are willing to apply to the process.

Slainte,
