biquad filters were just something I pulled off the cookbook, assuming it 
would be the next place to go.  And you know what they say about assume....

Coding is a yearly thing I do in the winter months, I try and limit how much 
time I spend on it as it is as far as time and energy are concerned, very 
demanding.   I intend to get as much done as pos without using libraries, 
get the main elements there and working, and then I'll expand into ladspa in 
the future.
