Hi Jules

Pulled the latest code today and currently refactoring my code to take into account the recent IIRFilter changes. Really like the new approach but I can’t see a method of implementing my own filter designs and settings coefficients manually anymore. Before I would subclass IIRFilter and go from there.

Am I missing something? Or would you consider making the constructor ‘IIRCoefficients (double, double, double, double, double, double) noexcept’ public?



Good request! Yes, I’ll provide some public access to that for you…


Just seen the commit, thanks!


Hi Jules

Sorry to dig up an old thread but I have another request… can you provide access to the coefficient array c? I need the raw coefficients for some magnitude response trickery, and it would be nice to use the filter designs that are built-in.



Yes, will do.
