I suggest just porting STK from C++ to D. It is well documented, 
suitable for a D-range implementation, is written for clarity 
over speed and uses a BSD license:

https://ccrma.stanford.edu/software/stk/
https://github.com/thestk/stk/blob/master/include/Blit.h

It also contains a wide range of physical models (waveguides etc).
