at least from my measurements I can tell YPAO R.S.C. doesn't influence the phase/time domain, it "just" works on the level/frequency.
the PEQ part I limited to 7 bands with fixed 1/3 octave steps, the R.S.C. filters are much more precise but you can't change them manually They are not even visible.
the "worst thing" about YPAO is: there is no R.S.C. part for the subwoofers and the PEQ is even limited to 4 bands (you can also use max. 4 bands below 500Hz for the other speakers). Thats make it almost useless for subwoofer correction and in most rooms you can improve the result with additional DSPs (within the sub or externally as MiniDSP, Antimode etc.)
personally I prefer the YPAO equalization over Audyssey XT32 for the "normal" speakers.
there are other features of YPAO as well:
YPAO Volume (Audyssey: Dynamic EQ) -> automatic and adaptiv Loudness
it's a simple on/off function and while Audyssey has the Reference Level Offset (0, 5, 10, 15dB) you have to do dirty tricks with the input level adjustment (+/-6dB) to shift the RLO.
Adaptive Dynamic Range Control (Audyssey: Dynamic Volume (don't get confused by the different meaning of volume)) dynamic compression
simple on/off as well and unfortunately in the newer Yamaha forced combined with YPAO Volume. You can't use ADRC without YPAO Volume, I hope they fired the guy who "invented" this stupid idea.
Audyssey offers 4 levels of dynamic compression, off, light, medium, heavy.
having this said, in my opinion the ADRC=on works better than all the Dynamic Volume settings, for example if you are listening to a TV show in the middle in the night having people sleeping next door.
the Dialog Enhancer works really well in the Yamahas
in the "smaller" Audyssey models it's just some kind of "center level quick adjust", where the Yamaha function really analyses the sound and enhances the dialogues only. Just the brand new top models with Audyssey have something comparable and I haven't tested it yet.
and my personal favorite function (besides the DSP modes) is the Dialog Lift!
there is a virtual mode which is useless from my point of view, but together with front height speakers you can raise the origin of dialogues to the center of the screen.
I hardly understand how people install a 7.2.4 or meanwhile even 7.2.6 speaker setup with over head effects and the movie actors are still talking out of their feet or even below, that's completely annoying.
