I was thinking it would be nice to have examples of what double
precision enables with audio. I guess its pretty subtle for the most
part, but your examples are good on your site. I like the idea of Pd-
double now becomes useful for general purpose math. And the IR
measurement example is a good one too. Perhaps this doesn't really
exist, but I was thinking it would be great to have a patch where you
could hear the difference between single and double precision.
