I don't really care much that I had to register. Now I'm getting more and more into PD and will ultimately probably post some patches or comments too, or long for sharing thoughts and tossing ideas around.

I guess that heavily depends on what you do with the wave. If you chop it up violently it will probably generate new higher frequencies which will fold back at the nyquist-frequency - at least as far as I know.

My main reason for registering at all was to get all the nice patches in the attachments
