The following=A0suggestion is not very scientific; it's more along the line=
s of "When life give's you lemons, make lemonade."

What you can do is to place the two AT3032 microphones on a short bar, one =
pointed due left and one pointed due right.=A0 The separation is determined=
by the length of the microphones.=A0 The spacing gives some directional cu=
es, but the non-obvious part is that the narrowing polar pattern at high fr=
equencies also gives you some directional cues.=A0 An omnidirectional micro=
phone of the size of an AT3032 is typically down several dB for sounds 90 d=
egrees off axis above 5 kHz or so.=A0 I've tried this, and it works.

What would be far better would be to mount the microphones in a spherical b=
affle of diameter 20 cm or so.=A0 You want low weight, and that's a problem=
.=A0 But it should be possible to make the baffle out of rigid foam and the=
n to put a thin layer of something rigid and non-resonant on it.=A0 My effo=
rts to make such devices have always been of the sort where I didn't care a=
bout the weight, and that makes everything different.
