Playback configuration Believe it or not, if you do a surround recording, it is more likely that your end listeners have a reasonably correct speaker configuration than if you're working in 2-channel stereo. Think of all your friends (this is easier to do if you think of them one-by-one, particularly if some of them don't get along...). Of these people, think of the ones with a stereo system. How many of these people have a ``correct'' loudspeaker configuration? I will bet that the number is very close to none. Now think of people with a surround sound system. In most cases, they have this system for watching movies - so they've got a television which is the centre channel (or there's a small speaker on top), a speaker on either side and a couple of speakers in the rear. Okay, so the configuration probably doesn't conform to the ITU-775[Union, 1994] standard, but it's better than having a stereo system where the left speaker is in the living room and the right speaker is in the kitchen.
