<<"Wavy" is the best word I've found so far to describe a phenomenon I've n=
oticed consistently for many years on recordings captured with ORTF, M-S an=
d spaced-omni arrays. Not a partial blending toward mono, but rather a very=
subtle but audible "jitter" or "inter-channel instability" in these non-ba=
ffled arrays. Sorry, that's the best I can do at describing it.>>
Trying to grasp your meaning here. I'm imagining this to be the indistinct =
localization of sources around center? Things which somewhat jump back & fo=
rth between left & right speakers but which are just a few degrees off cent=
er? And the shift occurs with slight head movements?
<< I've been able to greatly reduce the effect in ORTF-type pairs by moving=
the two mics closer and closer to each other until, at some point, dependi=
ng on the mics, the "wavy" effect seems to become unnoticeable.>>
So, XY?
<< Of course, the desired stereo width gets reduced too.>>
Sounds like you're preferring stereo based on level difference over stereo =
based on time difference. Except . . .
<<Why this would occur in M-S recordings is absolutely beyond me, but it's =
almost always there.>>
Except that MS is entirely level based. So, I dunno.
