Even though I've been on the forum for a bit, I still feel that this is a newbie type question: I was flipping through the menus of my atsc reciever, and noticed a certain feature: Enable Dynamic Range Compression The manual, as is usual for a samsung product, is a bit light on details, but I gather that it can sometimes be used to equalize volumes from various dolby digital sources. A similar feature can be found on my Mac's DVD player. The trouble is, I don't know whether this is a desirable option. Compression reminds me too much of improperly mastered CDs, with a compressed dynamic range. I'd like as much dynamic range a possible-- my receiver's (Onkyo TX-SR502) dolby midnight modes can be enabled if I don't want to tick off the neighbors. So, what does DRC do? Is it useful? Or is it an attempt to placate less discerning ears?
