I tried to record sound track from an outside player such as CD player, plug in to microphone of my notebook. I tried both mono and stero, but I can not record both R and L tracks. How could I do that and see both tracks and both FFTs in wavepad? Thanks, Carl 
your first mistake is plugging in to the microphone
you need to use a line-in jack
if you don't have one, you have two options
get a USB converter to makeup for the jack you don't have,
[ such as M-Transit ][http://www.sweetwater.com/store/detail/Transit/](http://www.sweetwater.com/store/detail/Transit/)
or play with the input on the mic input, [ in recording devices ]
but I don't see that working out too well, because you'll have mixed
impedences that won't like each other, you'll get a crappy sound at best.
