I will be recording in public places where, in many cases, the street
performer, or "busker", as they are sometimes called, may be seated with

major
comb filtering problems, although I do not know whether the result will
be
unpleasant.

One way to avoid this comb filtering would be to use a stereo boundary
mike
placed on the floor or sidewalk. A ray trace diagram suggests that above
1K,
with this arrangement, the mike could be positioned to pick up
considerably
less early reflection than a standard single-point stereo mike.

What are the more reasonable offerings of stereo boundary mikes that are
suitable for recording music?

Due to the rumblings of the infrastructure, the mike would have to be
placed
on a foam pad. Would this impact mike performance?

Hmmm, why dont you just go out with a couple of mics, with a
"busker",record something, and see what happens. listen to the
recordings, then try again, and see what works

Theory is fine, but you need to mix it with practice

I don't have the mikes.

Martin, i have a small pile of boundary mics which i use as the need arises.
a Crown PZM did a wonderful job for me picking up bagpipes... but then i'm
coming to the conclusion that anything will work with bagpipes .

you need to think first of the most prominent problems you will encounter
before worrying about secondary problems. your biggest enemy will be wind
noise and crowd noise.

i find that optimal placement is in front and/or above the audience. usually
i use a pair of Rode nt-5 on a spreader bar on a mic stand with a boom at
full extension. on a moderately windy day it takes a couple of windscreens
on each mic.

with a PZM or PCC, unless you are standing there guarding it you get people
walking on it, standing on it and talking, drinks poured in it, and just
about anything else that is undesirable and irritating.
