Three questions:
1) I'm playing around with an Audacity Mid/Side plugin that I've never used before. I can do M/S -> XY conversion and there is a width adjustment which is nominally 1.0, adjustable from 0 to 2.0. I'm guessing 1.0 is a 1:1 mix, 0 is "all mid", and 2 is "twice as much side as mid". Can anyone confirm or deny?
2) I remember seeing a chart somewhere on the internet, here or outside of here I can't remember. It basically said something like "1:1 = XY 90*", and 1.2 ratio is like Hypers at 110*, etc. Anyone know where I can find that again?
3) There is a concept called "equivalent stereo width factor", or something like that. I can't remember the proper term so I can't google it. The idea is that the spacing and angle of near-coincident convert to a single number of equivalent width... Anyone remember what that's called?
Thanks.
