The "recentering" consists in lifting the volume of the lower channel. I don't degrade the quality of the track, nor its sound but indeed most of the time the left and right channels don't give exactly the same results through EQ because of their orchestration. I took back a lot of tracks from the beginning recently thinking I would have better results if I recentered the stereo first and I found out that it was not necessarily the case, so no worries.
A precision on this: I don't work from the OE3 equalized tracks, but most of the time from my first mixings: A basic equalization meant to remove the more obvious abuses or noise. And also I can balance a track and keep my EQ settings as filters that are not definitively applyed on the track.
However if I balance a track that is definitive what is rare, the lifting is generally too low to really affect the final result, or when it does it always gives a better one, as for "The Duel".
... But you're right to ask, one must pay attention to these little details.
Oh, now I understand what you mean by "recentering". Sorry, I was a little confused over what this exactly meant, thanks for your detailed explanation. I listenened again to your new samples with higher volume as I couldn't do that earlier or I would have woked up the neighbours, and I can't believe this is actually sourced from the official CD's, it sounds so different! in a really good way. This score is in good hands ;)
