Record Left and Right rear channel audio only

Hi guys, this is my first post here I did a search and couldn’t find anything on my particular topic. Is it possible to record only the left and right REAR channel audio only? I suspect that the answer is no, but I can’t find any information elsewhere. If it’s not possible, is there any software out there that would allow me to do such a thing, even if it’s pay-for software.


2-mono to stereo splitter cable plugged into line-in of the computer?


You need to give us a hint where the channels are now. Analog cables across the floor? AC3 bitstream? Three stereo audio files? Broadcast television?
