That is stereo! Where ever you are - in your house, on a
commercial flight, hanging upside down from a set of parallel bars,
rowing a canoe across a rapid, etc. - is stereo.

How can that be? Sound which originates from a single source travels
into your left and right ears. A violin or a person singing cannot
be consider stereo. However, when we playback the recordings in
stereo we are listening two identical violins or singers over the
left and right speakers and it cannot be correct but we accept that
as natural.

That never happens, unless you're sitting in an anechoic chamber.
Sound comes from all over.
