I don't watch a lot of TV, but two programs stand out as awful vis-a-vis sound - Buffy, and Alias. In many scenes there is a pervasive hissing deep space type hum, that seems to build until a character actually speaks, when it is sharply reduced, but as the words end, the background noise resumes... It often seems to be worse in scenes in crypts, warehouses, etc, so I tend to think it is a deliberate effect. If so, its awfully irritating. It almost seems as tho some engineer recording the sound sees dialogue approaching, and reduces the level on the buzz input control? Anyone else experience the same irritation with this? Can anyone explain it to me? BTW, is it anything like the "compression" technique used to give punch to crummy pop music in car stereos?
