Select your preferred downmix
Code:
function Dmix3Stereo(clip a) # 3 Channels L,R,C
{
flr = GetChannel(a, 1, 2)
fcc = GetChannel(a, 3, 3)
return MixAudio(flr, fcc, 0.5858, 0.4142)
}
function Dmix4lStereo(clip a) # 4 Channels L,R,C + LFE
{
flr = GetChannel(a, 1, 2)
fcc = GetChannel(a, 3, 3)
lfe = GetChannel(a, 4, 4)
clf = MixAudio(fcc, lfe, 0.2929, 0.2929)
return MixAudio(flr, clf, 0.4142, 1.0)
}

Dmix3Stereo
#Dmix4lStereo
Normalize()
And encode with EncWAVtoAC3 v3.0b
