Mean seems to be the same as the simple maths concept:
"Produce mono audio by taking the mean of all audio channels."
That's effectively the same as the sum of left and right, which is how we derive mono from stereo in the analog world. Dividing by a constant merely changes the level.
I'm not sure if stereo = false would mono'ise or just drop a channel so be careful if you have any tracks that rely on stereo vocals. Definitely worth testing either way.
I was in an apocalyptic mood one day, so I used Audacity to create a test audio cut consisting of 666 Hz on the left channel and 777 Hz on the right. Most of the AM stations I deal with want to stream their audio in stereo, but their transmitted signals are mono. If I put even a little of the test cut on the air, I can tell immediately whether I'm hearing the sum of left and right or just one or the other.
