I have both C code (compiles under linux/cygwin/mingw) and some Matlab/octave code. I'll give you my coeffs and diagram, but you need the Matlab SDM toolbox to genereate your own coeffs.

Specifically, I would like code to do 4th order delta-sigma de-modulation. Any suggestions?

They do not allow hotlinking so I can't link the actual file. You have to go there and right-click the spaceghost link it to download it. I do not have a wave file posted here, but on the next post:

So what do you think of my explanation? Can't wait to see my simuation code? Just kidding. Thats like you asking me to comment on how well those fabric patterns go with that furniture.
