I like this one, but I am not sure that the space after "stereo" will work.

I chose 63 here because it is the natural one with channel layouts: they are
stored in a signed 64 bits integer.

I will not have time to properly re-test and commit this until tomorrow. If
you want, you may do and test the final documentation change and push.
