I've heard so many good things about Lexicon's Logic 7 processing, and in a conceptual sort of way I always thought I understood it. But lately, as I think about it in more detail in the context of an impending processor purchase decision, I want to make sure I understand the details of how it works. I've done a little searching on some forums but wasn't able to uncover a good explanation. This is probably a "softball" question for you Lex afficianados out there, but I just wanted to make sure I understood Logic 7 processing correctly. So, my question is can someone explain what is happening to a movie soundtrack when Logic 7 is applied to it? Take Dolby Digital 5.1, for example. If I select Dolby Digital 5.1 as my surround track option, and apply Logic 7 to it, my uninformed guess is that the front soundstage stays exactly as it would with no Logic 7 processing. Is this correct so far? Do the side surround channels produce the same information regardless of whether Logic 7 is used? To put this question another way, does Logic 7 modify what comes out of the side surrounds? As for the rear surrounds, is the surround information "taken" from the side surrounds and matrixed into the rears? If so, does it leave the side surround information exactly as it would be with no Logic 7 or is the side surround information also modified in some way with Logic 7? I have the same questions relating to DTS 5.1 and DTS ES 6.1 Discrete formats. Thanks for the help in clearing up my questions?
