a track recorded in Mono has no left and right information on the track.
When it plays, it will put the same output down both left and right channels.
I just bought the Beatles' Mono Box Set and imported it to iTunes. Because I have tons of room left on both my iPod and Mac, I did something I never do...imported them using the AIFF encoder. (I left the setting on Automatic.) Now, when I look at the info for the files, they show up as Stereo. I don't have a of technical know-how and I'm assuming that this simply means that the songs will play in two channels. (I know that if the original masters are mono they can't actually "play in stereo".) But my question is...would there have been any advantage to my setting the encoder to Custom and the Channels to Mono instead of Stereo? Thanks.
