good for you, get back to me on what you find out. Perhaps you will then understand why I am an acutally working professional engineer. For a stereo recording you need record the initial source with at least two mics onto two separate tracks (or one stereo track that which contains both left and right information) Some techniques to do this include x/y micing (which I often used), spaced pair, M/S micing, with sub-variations on these micing techniques such as ORTF, Blumlein (which I like to do with ribbon mics for drum overheads in a nice sounding room), Decca tree, etc. Once this information is recorded on playback it needs to be panned left and right to retain the integrity of the left/right information, otherwise it essentially remains in mono.
So what did ya find out?
Oh I guess I was right after all!
The next question is, why do I even fucking bother ungrateful bastards.
