+L-R = 0 +L+R gets you a mono file (before volume reduction). +L-R cancels out. Try it out in a wave editor with a sine wave The figures I wrote in my previous post use + as a summing operation, not to signal polarity I discovered the process on my own, so I'm sure there are better ways to do it, I'm not a recording engineer :)
