Ok, I've had an idea, but I don't think it will work.

I've been looking at PSoC families, and there is one that has an
additional group of analog blogs that can be configured as single
slope ADCs. I would guess that these would be too slow to detect
overall excessive analog audio, correct? My thought was to route each
input through the mixing matrix, but also to an ADC. If the level
exceeds some measurement the device would automatically duck down the
gain on the mixer. I think the speed of the ADC would mean that this
isn't possible, but I'd love a double check.

Thoughts?

A common mistake that people make when trying to design something
completely foolproof is to underestimate the ingenuity of complete
fools.
