I think that the distance between the elements is the main engineered porti=
on, IMO.=A0 You can have your mics at any angle as long as the distance (17=
cm) is achieved.=A0 You can't officially call it ORTF that way, but still.=
=A0 There is quite a bit of play in that number as your mic elements are pr=
obably 1cm or larger in width.=A0 And the speed of sound varies depending o=
n factors.=A0 If it sounds good it is good.
I'm not so sure what's so magical about 17cm, but it seems to make a notice=
able difference IMO.=A0 Even when the mics are parallel (0 degrees).=A0 Or =
you could play it safe and keep the mic elements as close as possible so yo=
u can mix to mono while still having a wide soundscape in stereo.=A0 Variou=
s techniques, some of which have names.=A0 On a side note, taking two OSP s=
tereo bars and rigging them together by the two inner holes gives you exact=
ly 17cm between the center of the outer open holes.=A0 It's what I like to =
call my microphone ruler.=A0 Unfortunately there is no mounting hole left i=
f you rig the bars up that way.
I tend to want to zoom in on sources at a distance so I rarely get past 90 =
degrees myself.=A0 Not that OMNI mics are supposed to be directional, but o=
nce you start factoring in the rigging or the landscape there is some direc=
tionality to them.=A0 If only because everything is being held against a su=
rface due to gravity.=A0 Which is better than the alternative for us lifefo=
rms.
