Kind of a long shot, but do notes happen to exist for exactly how the various voices were processed for the AoA:DC lines? The GTVA radio-voice filtering, specifically. I would guess but only very tentatively that Battuta was responsible for that? I have done similar filtering in the past so I understand the general techniques that were likely used, but if purely hypothetically someone wanted to recreate the exact sound, trial and error could be a pretty long process. Even with notes an exact fit is unlikely, but it'd probably help.
