I was thinking that this should be generalized into a general biquad~ library, so with objects like [bandpass] to calculate biquad coefficients. The calculations could all be written in C as a shared library, then the Tcl code could use those C functions also, which I think would allow for 1 pixel resolution. My guess is that doing the math in C would make things noticeably faster.<br><br>.hc</span></blockquote></div><br></div></blockquote></div><br><div>
