This is a Mixing Matrix to downmix 5.1 to stereo Dolby Prologic II.

Note:
There are coeficients for Side and Back channels because both are valid for 5.1. Of course only one pair is present at the same source. There are both only for 7.1

EDIT: Remember use:

DirectShowSource("your audio input")
Normalize(0.98)
