I was trying to explore the channel down mixer algorithm. I encountered with a problem.

I have a clip in which Center and LFE channel are present and if I want to play on the stereo headphones routing Center to one channel and LFE to another does not make sense. Is there any standard that specifies how the mixing can happen in this scenario?? If so can anyone of you please point me to that?

If you have a 5.1 channel soundcard, I beleive the center and LFE come out of the same 3.5mm connector. In that case, you can just plug-in your head to that connector and you're done.

Or if this is a (non-encrypted) file on your computer, you can open the file in an audio editor (Audacity, Audition, etc.) and create a new stereo file edited & configured however you want.

FYI - A "normal" downmix does not include the LFE... It just includes thenormal bass from the other 5 channels.
