Is there a way to have the DSP core of an ADAU1761 (or other) measure the signal on the aux inputs, and adjust the mic inputs accordingly. Ultimately mixing them both together. I'm assuming that the mic inputs go through the DSP but the aux bypass it to the output mixers. I suspect the answer is 'no' since there is really only two channels into and out of the DSP, but I thought I'd ask. The alternative, I guess, is to create some hardware that the controlling processor measures the signal and controls the gain of the signal going through the DSP. Just seems messy to have to do that. Anybody got any other ideas?
