That's the xy configuration you mentioned earlier, right? One of the links I posted above has a section on that with diagram.highland-piper wrote:If you put cardioids overtop of each other, the left one pointed right, and the right one pointed left, kind of like this ^ where each line is a microphone, and the diaphrams are at the top, then it will record stereo. Since the centers of the diaphragms are in a straight line, it eliminates phase distortion. If you pointed that pair straight at the chanter, then the chanter would be centered, and the drones and the regulators would be slightly off to the left (more or less, depending on how far away it was).
FIG. 4: XY mic placement uses two coincidentally placed mics
(typically with a cardioid pattern) positioned to create an angle
of 90 to 135 degrees between them. By positioning the capsule
of one mic directly over that of the other, sound arriving at the
mics in the horizontal plane will be picked up at virtually the
same time, reducing phase cancellations. The XY technique is
highly mono compatible.
I discovered that quite by accident, the xy configuration, and wondered why the instrument sounded so good. One thing in the learning curve was that everything sounds better through headphones, so don't trust the recording to sound good on your car stereo if using only headphones. I finally located a great set of studio monitors. They don't work like regular speakers, but are designed to tell you the truth. If it passes that test, I take it out to the car. One engineer commented that 80% of all music is play on car stereos nowadays. My car stereo really is just the thing. The Bose is questionable, but I do play back a master CD there just to see what it sounds like. I use several sources to an idea of what the mixdown needs as a compromise for all systems.highland-piper wrote:Personally, I find recordings made that way to sound really great on headphones, but not as dramatic on speakers. Another common patter is to put the bases of the microphones together like V (where the diaphragms are on top (110 degrees is the "standard", developed by French television). I don't think a pattern like that would lend itself to pipes, but it might be good for a small group, if you didn't have enough microphones for each musician. The drawback is obviously that it limits editing possibilities.
