Well, it comes down to what one means by "process" and "signal" what tools one uses and what information one has access to.
If one works in the mathematical domain of bits then one can definitely model the transforms used by some audio software. It is rather trivial when it comes to software of the "bit perfect" variety, i.e. one compares a string of integers for identity. If one works on the analog waveforms output by the PC on the cable to the DAC, one can also model things in detail if one has complete models of the components used and "unlimited" computer time to run SPICE simulations. The problem only arises when one uses proprietary commercial off the shelf hardware and software. That's the fools errand, I should think.
Of course, models are only models and to the extent that they are simplified sufficiently to be practical they won't be accurate. The modeling problems for computer audio are not nearly as intractable as modeling global climate change, but then the budgets are hardly comparable either. :-)
