Btw, this seems to be a feature of almost all of the GGEE biquad coefficient externals.  Check line 67 on highpass.c, bandpass.c, equalizer.c, and so forth.  I&#39;m not sure how you would want to handle this, but keep in mind it&#39;s systemic.<br>

seems to have a hardcoded sample rate, which obviously causes problems when running at other sample rates...<br>

Nice catch.  That seems like a bug, no?  As far as I know Günter is missing-in-action on his code in the pure-data SVN, so it seems appropriate to me IMHO to commit fixes directly.<br>
