Defining upsampling.

> No, really. Do you accept marketing lingo as a defining body?

Werner, perhaps we should take time to define it now, for posterity, and use it consistently in future discussion. (though I'm sure like most of these things it will probably be forgotten by most in a few months). I am not that old, so I ws not sentient, let alone able to grasp interchangeability of the terms up- and over- in the seventies. :)

To me, upsampling is non-integer sample rate conversion, and that is what I have been using as definition until now. Oversampling is integer-multiple conversion. I believe Doug uses the same convention. I think this is largely consistent with today's marketing jargon, but perhaps not standard in the literature as you have implied. What's your perspective?
