I wonder if there's software out there to enable a PC or Mac to profile sounds ?
No there isn't.
There's only one Cristophe Kemper, and he invented the Kemper Profiling Amp.
Before he invented it no guitarist or engineer in their wildest dreams imagined it was possible, in fact after CK announced it and demoed it at NAMM guitarists still said it was "Vaporware", impossible.
Inventing the Profiling technology is only one part of the genius, creating the algorithm that makes the Profile sound, feel, and re-act like a real tube amp is even more genius.
