So what does that mean “Down in the Noise”? Several possibilities. The literal definition is an attribute which is so small that it is masked by background noise. We will talk about background noise and dynamic range later. For now I want to use it in a more figurative sense. Namely some (usually unwanted) attribute or characteristic of our reproduced sound that in practice makes no difference to achieving the goal of completely realistic reproduction. It could be distortion, or lack of smooth frequency response, or even digital artifacts. But none of these are deal breakers. They can easily be down in the noise.
OK. Hold on. I can hear you all now saying” I thought you said achieving perfect accuracy in reproducing the original sound field was required.“ Well it is a nice idea but for all practical purposes it is unfeasible. The guy behind the glass has other priorities. And no matter what you spend on your system (or room acoustics) you will never achieve a perfect copy of the original. It’s a good thing we all have a brain (no comedians please). Because in reality all you need to do is to fool your brain into believing the sound field is authentic. More on this later too. Still with me?
