precisely.
the "magic" in analog circuits does not come from the way it adds two

in-range voltages, which is precisely as stated above. take 0.1V, add

0.18V, get 0.28V. it really is that simple (we're ignoring temporal

effects that are similar for actual air pressure waves and thus not

relevant to a discussion of artifacts caused by recording and

playback).
the magic comes, to the extent that its actually magic (let alone

actually desirable) from the way it does more complex processing, such

as compression, limiting and EQ, and also the way that some media will

store the result when C is "out of range". even these can be

replicated to any arbitrary accuracy if you're willing to spend the

CPU cycles on it.
