Those look really interesting. Wouldn't they capture the sound I have to admit though it would be a great test

Hello all,
I did a lot of really stunning (classical) concert recordings with
in-ear binaural mics. I.e. you really don't need a dummy head, if you
are able to keep your own heard unmoved. It just requires a bit of
discipline. Small movements don't hurt, they rather drastically
improve the binaural imaging. The effect of different people
having different head shapes (HRTFs) is noticeable, but for the
purpose of just listening to music (and not doing angle measurements)
this doesn't matter much. The effect when listening with good playback
equipement and (open) headphones is really thrilling, quite immersive.
I don't know any recording technique providing better this "live"
or "we are there" feeling combined with the possibility to use
very high quality equipement at a moderate price tag (good
loudspeakers are a great deal more expensive).
The OKMs are nice, but even the "classical" variant is rather
middle class quality level. For really good results you can use
the DPA 4060 mini electret capsules. IIRC, DPA themself provide
some "binaural set" equiped with this mics.
I bought mine from "Core Sound" http://www.core-sound.com/bk/1.php
Cheers,

A good way to listen to binaural recordings using speakers is to
use a 'stereo dipole' setup; speakers are close together so you
see an angle of 15 to 20 degrees between them, and the recording
is processed using a crosstalk cancelling convolution matrix.
The net result is that each ear only gets the signal from one
channel, as with headphones, but you can still move (a little
bit) and turn your head w.r.t the sound stage. It works even
better with a second pair at the back, using the same signals.
The only practical problem is that the 'sweet spot' is quite
small. If two persons want to listen at the same time they
should be one behind the other, not side by side.
The latest release of JACE comes with config and IR files to
do this.

Thanks everybody for all the feedback. I spent a lot of time lusting after
the km-184s, but I decided to try my luck with the matched pair Rode NT5s,
being that they cost quite a bit less. In combination with the digimax fs,
recording at 96khz, the results were pretty darn good. With headphones on I
could hear the whole neighborhood (at about 8PM on a friday, so there was
some stuff going on a few blocks away, dogs barking, and at least 5 cars
drove by.....)
Later, I sat about 20 feet behind the the mics that were facing the forest -
and recorded http://www.taht.net/~mtaht/outside_cybernation.ogg on guitar,
just to get a feel for what the relative levels were like in this decidedly
non-optimal scenario. (the above ogg is downsampled to 48khz, and I haven't
actually listened to it yet. Remember that it's supposed to be at a fairly
low volume).
So there are issues with the stereo mix (the cars going by are coming up 5
levels of "S" up the mountain, then going behind the house, and up the
mountain) which is due to mic placement. I want to get a spacious - for
speakers - recording rather than a headphone one... I'm not sure what my mic
spacing or pointage should be like in that case with a cardioid pattern like
the NT5s have.
Also have issues with even the slightest wind, not sure what to do about
that.
All I have to do next is set my alarm for 4AM, clear out some disk space,
put the mics below my peach tree, and see what dawn sounds like.
Recorded about 8 hours of forest in ardour2 with only a single xrun....

It's so low that most of it's practically inaudible to me on headphones,
and mostly inaudible through stereo amp and speakers. And either there's
no guitar on the right channel, or the right volume level is zilch.
Outside of that, it does sound clean and clear.

I am researching like crazy -
http://www.wikirecording.org/Mid-Side_Microphone_Technique - looked
interesting... but I can't do that with NT5s....
