Simply reducing the gain of the mic input in Windows Mixer doesn't work.
Mic inputs (in fact laptop soundcards in general) tend to be noisy.
And mono. (In fact I think all mic. inputs tend to be mono; they use the 3
pole connector as a way of getting bias volts out for electret mic.s.)
Note that the mixer application in your Windows may make it _look_ as if
your mic. input is stereo, and produce a "stereo" file; But play it through
anything that gives you an X-Y plot (e. g. GoldWave; countless others too),
and the truth will be revealed ...
If you want to get stereo into something that has only a mono imput (most
laptops I think), you need an external "sound card", i. e. sound device;
there are several. (I'm assuming something like a laptop or other
non-expandable PC; if you actually have a sound card that only has a mono
input, get a new sound card.) The one I have looks like a ridiculously large
volume knob, with sockets around the base (it does actually have a knob on
top); it is a pleasingly heavy and apparently well-made unit. (Hercules I
think it is.) They connect via USB; beware, I found that USB1 wouldn't give
me stereo at 44.1 kHz, though it claimed it was (but on playback there were
bits missing, though this wasn't as obvious as you'd think!). [This _could_
have been just processor overload - the laptop was just below the min. spec.
on the sound thing box (300 or 350 MHz).] There are several such units, of
differing shapes.
