Weren't all those math formulas and standards the basis of the

Hello, Eric,
One of the two EQ implementations I looked into in depth was AME and
using modern components I had to shift the values slightly to create
a real-world graph like the one in Jay McKnight's paper on the
subject. It was an interesting tradeoff between matching Jay's graph,
the SPICE graphs from two implementations and real-world components.
The other EQ implementation that I looked into in depth was cassette
equalization, and it, too, is very imprecise and left that way.
I think it's safe to say that the real world does not follow precise
mathematical curves in many areas.
