I was having a discussion with a coworker recently about lossless vs lossy. He argued that the *only* thngs missing in a high bit rate lossy mp3 were frequencies that most people cannot hear anyway. While I know that it is not quite that simple, it got me thinking about a few things, one of which is the following scenario:
Suppose you have one recording of nothing but a 1000 hz tone (Recording A). Now say you have another recording of a 1000 hz tone, but the second one gives the listener a strong perception of depth (Recording B). Since sound itself is analog, which means that it is nothing but movement of air at various frequencies, it would follow that the the two recordings are different because of the presence (or lack of) additional frequencies that give the feeling of this depth. Yet the recording is still nothing more than a 1000 hz tone. So, my question is this - what is it exactly that gives recording B the sense of depth? And, are these differences considered "disposable" by a lossy codec and being thrown away? And please - I would like to not get into the old lossy vs lossless debate. I just am very curious.
