I assume that the seven bands (63Hz, 160Hz, 400Hz, 1kHz,2,5kHz, 6,25kHz und 16kHz) mean "0Hz-63Hz", "0Hz-160Hz", ... and not "0Hz-63Hz", "63Hz-160Hz", ..., right?
I would like to use 3 x 68k (=204k + tolerances). I guess that this is o.k. for a qualitative peak-meter!?
...but to build a two band peak-meter with one band going from (roughly) "0 to 1kHz" and the other going from "1kHz to 16kHz" I could use this formulas:Band1: (peak_63Hz + peak_160Hz + peak_400Hz + peak_1kHz) / 4Band2: (peak_2,5kHz + peak_6,25kHz + peak_16kHz) / 3- right?
Would the "max263" IC be a feasible solution for two band filtering? One could switch the cut-off frequency fast to get a two band filter out of a one band filter!?
