Though this can be inaccurate due to the improper distance of your sound calibrator to the mic. | |

And so far the ADC is somewhat a blackbox to me, manufacturers of home devices such as computers and mobiles do not clearly label the relevant specifications. My teams plans to use the readings of a professional calibrated sound meter to reverse-calculate the pre-amp gain, and this sounds a very challenging task. Any suggestion? | |
