If your mic was a stereo mic then nothing can
recreate the original sound.  There is not
enough information.

Ambisonics and Ambiophonics couldn't be
more different.  As Fons suggested, a toaster

on whether you want to toast bread or to cut

Super Stereo adds nothing to the stereo
source.

I must suggest that it is about time you started
reading the numerous references people have
given you.  Nobody can do this for you.
