OK, here's what I'm trying now: I have the GOUT 2.0 English and GOUT 2.0 Spanish tracks loaded together in Audacity. I'm comparing them side by side, with a preference for English dialogue of course, but a preference for the Spanish mix as it is based on the mono version (it definitely has the right klaxons).
This will give me a hybrid mix consisting of all the 1.0isms I can eke out of GOUT.
