Hi, Sounds very interesting and looks familiar with what I am doing with the MAX414BCPD quad act OP Amp. I am trying to make out of the mic input a sort of Spectrum Analyzer. The question I have I am running on a DC offset of 5 Volts (rms) and ask myself if this is not too much of Volts for the mic input? I saw in your Left and right approx uV....Thanks for any hints
