I'm considering using multiple mics to get amplitude information...maybe 8 mics maybe 16... What would be the best way to sample each of the mic levels with a PIC. I want to constantly do this. Does this require an analog multiplexer and one A to D chip?...PIC addresses multiplexer and the addressed line(analog voltage) is fed to the A to D... I guess I would also need an op-amp or something to amplify the mic's line levels? Does that sound(no pun intended) right?
