left = front_left + front_center * sqrt(1/2) + back_left * sqrt(1/2) + lfe
right = front_right + front_center * sqrt(1/2) + back_right * sqrt(1/2) + lfe

See: SDK, foo_dsp_standard\dsp_standard.cpp, class dsp_51_downmix, where 6ch order is front_left, front_right, front_center, lfe, back_left, back_right.
