I was skeptical to see the claim that csound "cannot do oversampling"
(not because of some knowledge of oversampling, but rather past
experience with a) how comprehensively synthesis techniques are
represented in csound and b) how easy it is to prototype synthesis
techniques directly in csound). There is an article on csound journal
http://www.csounds.com/journal/issue6/BandLimiting.html describing the
hows and whys of oversampling, and it uses pd rather than csound in
most of the examples(!). This should be informative because not only
does it show how to make a butterworth filter in pd from scratch, but
it gives a good explanation of what oversampling aims at, and how to
implement it in just about any computerized audio processing
environment.

Did I misunderstand what I have found about oversampling, or is it
just another name or special case for bandlimiting of arbitrary
signals?
