I have heard, admittedly second-hand, of another restoration project (or 
maybe the same one) which involved computer-modeling of the cone that 
Caruso sang into (which was apparently much like the horns used as 
"speakers"), and of its effects on the sound, then applying this 
transformation in reverse.  Needless to say this was a research project,
not a commercial endeavor...

Anyone know any more about this research?
