I don't really understand this ASCII art.  If you don't mind, could you pass a patch along?

Does anyone have a set of tutorials, abstractions, or are their any documents available which go into further detail into these objects?  For starters, I'd like to build a few simple classic filter types

for [lop~] do

[*~]\____[expr $f1*3.141593*2/$f2]
 |        |
[rpole~]-[expr 1-$f1]

where the top $f1 is the frequency and the $f2 is the sampling rate.
