With my two microphones, say mic1 and mic2, I did a little experiment: I
recorded my voice with mic1, using sox, then listened to the so created .wav
file and the sound was heard only on the left channel.  Instead, doing the same
with mic2, the sound was heard on both channels.  How should we conclude?  It
seems to me that we should conclude that:

1) the mic input on my PC is stereo.  In fact, it is a laptop, nay a netbook,
   doesn't have a line in and it is reasonable that its mic input is also a
   line in;

2) mic1 is mono;

3) mic2 is stereo.

Do you agree?  But then, if it is so, my rough home made live piano record,
done using mic1 and mic2 plugged together in a one-male--two-female splitter,
*is* actually stereo...?
