Trust not protection to a software implementation on a PC. If you're really
worried about overdriving an amplifier, then you need a hardware input
limiter of some sort. There's just too many things that can go wrong in the
PC environment (oops, it just hung, my protection loop froze..). Remember
that the dttsp core has to get an input from the ALC signal, and then go in
and adjust the gain, which then changes the levels of the signals emerging
from the DAC.
Software is ok for this kind of thing, but you want it running in a
dedicated processor (e.g. That PIC).
