Anybody looking for a way to gauge the overlap of parametric EQ? This thing has become indispensable to me: http://www.musicdsp.org/files/rbj_eq.xls

The "EQ1" tab is useful for shelving. The "EQ All Peaking" is the thing that helps me get the line I want.

Yeah, it's a known issue, for instance in Caps EQ.

Cookbook R-B-J parametric is Direct Form I, which breaks at subbass with single precision due to coefficient quantization - this effect is not shown in this Excel.
It can be reduced by smart coefficient grouping as shown in the DSP newsgroup post.

Now then, the real solution is to use fixed point math with error compensation.
