Is there any "knee" code available for tweaking Compressor Tables?

I have everything working on my ADAU1701 board.  I can do PRAM writes and build my own compressor tables but I do not have the nifty "knee" function which smooths the transition from expander slope to compressor slope.  This knee function in SigmaStudio is very useful and I'd like to add it to my controlling microprocessor code.

 

BrettG wrote a nice app note entitle "Compressor Table Format - Changing compressors at run-time" which I implemented.

Now I'd like to add the "knee" function.  Specifically how was the "knee" computed?

 

Any help appreciated......

 

Thanks in advance,
