What does stereo recording achieve? I noticed that the left and right channels of some stereo samples don't sound the same, and loaded them into audacity. The program confirms my suspicion that the sounds vary greatly in characteristics. For a vibrato filled note, most often only one of the channels displays the wavy pattern induced by the vibrato. Is this what stereo recording is supposed to do? So the sounds mixed into your music will have certain instruments placed to the L/R side of the listener?

If it has two separate channels, it's stereo, no matter what's on them.

Even if the two channels are identical? Or what if the two channels differ only at sub-audible levels (such as when a mono master tape is played back with stereo heads)?

If they are identical, they are not separate.
And what do you mean sub-audible levels? If you play mono recording through stereo heads, there is also identical information on both channels. Not stereo.

No, tape hiss will be different in the two channels. There may also be an azimuth misallignment that results in a small time shift between channels.

IOW, if you invert one channel and add them, you will not get digital silence.

I'm not arguing against your definition, only trying to understand it.

I am sorry, but tape hiss and head misalignment are hardware errors. I can't take them into account IF the program is recorded mono.
We all know what mono is, I hope - complete recording mixed into one channel. So, if we play it on stereo or surround equipment, it will still be mono, because it is recorded on one channel.
Stereo is recorded on two channels. If the source is mono (from mono tape, for example), then it's mono recording, even if you record it on 6 channels, it's mono.
If there is channel separation that you can hear, than it's stereo recording.
