I dedicated my night to reading this whole thread. Ana mentioned that audio.ogg file or whatever, and seemed to assure us that it was relevant. Did we ever reach a conclusion with that?
The only other piece of relevant information is that static photo posted earlier.
I'm getting quite tired of useless screenshots from Ana's conversations, just post them on another thread or something, unless they're deemed relevant to the ARG after being posted on the separate thread.
EDIT: Maybe throwing this whole discussion onto reddit or 4chan would help? Then again...
