No, this only requires to be mixed in mid and side channel at the same time.

Yes, I know there exists a Version 3.1.1, but I wouldn't go so far to call it a release to the general public. Or do you know where to get one?

I can't tell for sure, but I would bet 0 at low quality encoding and 1 at high. Why? because 0 is the fastest method and 1 the slowest of them.
