Hi all,
I have a number of 5.1 wav files encoded in DTS. I would like to
downmix the 5.1 DTS to a stereo wav. After googling and because I am a
Linux users, I've found out that my best bet is to use mplayer and the
pan filter. I have tried to do this:
Left = 0.707 x FC + 1 x FL + 0 x FR + 1 x SL + 0 x SR + 1 x LFE
Right = 0.707 x FC + 0 x FL + 1 x FR + 0 x SL + 1 x SR + 1 x LFE
with the following command:
mplayer dts.wav -vc null -vo null -ao pcm:fast:file=stereo.wav -af
pan=2:0.707:0.707:1:0:0:1:1:0:0:1:1:1
as I understand that in DTS, the channel ordering is:
DTS: FC, FL, FR, SL, SR, LFE
but I am getting a file where the left channel is much louder than the
right channel. Is this because my assumption for channel ordering is
bad? Or am I using the pan filter incorrectly?
By the way, are the coefficients I am using for the pan filter OK or
can they cause clipping?
Thanks

Those who fail to understand C++ are doomed to reimplement it. Better. [Jez]
