Independent 2 channel source to joint stereo?

[chros]

I have a trailer (which has wrong mastering, I think), and the 2ch AC3 audio is independent: the music is on left speaker, the dialog is on the right.

Can I create a "normal" joint stereo audio from it? (eg. in avisynth)

Thanks

If you want mix left with right speaker you obtain a stereo with two equal channels. You can use a Audio.avs:
#a = NicAc3Source("path\your.ac3", DRC=1)
a = NicAc3Source("path\your.ac3")
fl = GetChannel(a, 1)
fr = GetChannel(a, 2)
m = MixAudio(fl, fr, 0.5, 0.5)
MergeChannels(m, m)
And after:
bepipe --script"Import(^Audio.avs^)" | yourEncoder -yourParameters

... you obtain a stereo with two equal channels.
You are right. And thanks for this script...
