Yes. As I said, I'm sure you can get pretty cool sounds out of this 
effect, but if all you're looking for is a way to make a cleaner kind of 
stretching/shrinking, it's the wrong place to look for it, which is why I 
was being negative about it. If the point is to make funny-sounding stuff, 
you probably have something more interesting than a shovelful of allpass 
filtres here.

On a related note, gridflow/examples/postdigital.pd is an example of 
messing with a setting called "quality", _lowering_ it until it looks so 
low-fidelity that it becomes _interesting_. Then it shows the frame 
difference with the original image, which is even more fun. I think of 
postdigitalism as about not taking quality settings literally, which is 
why I came up with this patch under that name, or came up with that name 
for that patch.

Note that my use of the term is tongue-in-cheek and I haven't read Kim 
Cascone nor Roy Ascott, and chances are that I'm not going to do it soon 
(I have a large pile of unread books in the queue and it doesn't get any 
smaller). But I enjoy talking about those æsthetical issues a lot, just 
that I tend to use my existing background instead, which may give wholly 
different results... e.g.: what if Claude Shannon had written a book named 
«Différence et Répétition»? that's the kind of question I sometimes ask 
myself.
