GH,
> can you think of a reason that it would be a problem to mix in the same acoustic space that you have recorded in? Will this cause a translation issue? <
I have heard people say it's bad to record and mix in the same room, and I agree to an extent. When I record a live string section with mikes far away, I can hear the sound of the room in the recording. That's fine and as it should be. But when I play it back and stand way back from the speakers, I hear more of that same sound yet again.
So I have decided to add a little more fiberglass absorption to reduce the room sound, which I plan to do soon. Even though my room is quite large by home studio standards, it's still too small to expect a sound free of room tone. The best part of my room is the hard wood floor, and I will not change that! Just add a little more absorbing on the walls and ceiling.
Also, the "room twice" effect occurs only when I stand well back from the speakers. Up close, in the heavily treated part of the room where the speakers are, the sound is always very clear and neutral.
The more important part of your question concerns translation. I think that has more to do with proper bass trapping than almost anything else.
