I found this analyzer very informative. -24db ramp (which is 4.5db tilt) perfectly shows overall balance. CPU consumption is ridiculous, only about 0.1%, even in 65536 blocks mode. Beautiful GUI, but no mid/side mode and only VST3, so in Live only through some patcher. Yes, there are plenty of great free analyzers on the market already, but this one is kinda perfect for me.
