I don't see how we'd do it --- we'd have to somehow model the exact noise characteristics of both our room and our microphone channel in a way that we could accurately simulate it. The room itself is reverberant, not especially regularly shaped, and there are several different known and somewhat non-stationary sources of nosie. Doing a simuation seems to be way more work than just recording a bunch of data through the channel, if it's doable at all. Cheers, rif
