Hi,
I've got another question that has been puzzling me. I have a 7.1 home
theatre system and use iTunes to play music. To my knowledge, when playing
a stereo file, iTunes will only use two channels. Of course, I can use the
amplifier to add propriety surround sound to use all the channels. But
suppose that I want to use the Mac to control the sound layout. What are
the options?
On top of what Paul suggested, you will want to look up references to
"upmixing" and "ambience extraction"; the latter being a standard way
to achieve the former. Technically non-trivial, and more than one way
needless to say. Patents abound.
