Uhm... what do you mean by that? I'll try to be clearer.
According to the download page, these files have to be played with a
Dolby Pro Logic II-compatible system. They look just like normal stereo
files to me (i.e. no AC3 or DTS) so I guess they're matrix
encoded/downmixed. As I don't have hardware with Dolby Pro Logic II, I
would like to 'upmix' this in software, so I can play it properly. It
found a downmix option in ffmpeg, but no upmix option.
Anyone, who knows more about this?
