===X-Y technique: intensity stereophony===
[[File:XY stereo.svg|thumb|X-Y stereo microphone placement]]
Here, two directional [[microphone]]s are at the same place, typically pointing at an angle between 90° and 135° to each other.<ref>{{cite web |url=http://www.rycote.com/images/uploads/The_Stereophonic_Zoom.pdf |archive-url=https://web.archive.org/web/20110531142452/http://www.rycote.com/images/uploads/The_Stereophonic_Zoom.pdf |url-status=dead |archive-date=May 31, 2011 |title="The Stereophonic Zoom" by Michael Williams |access-date=October 17, 2011 |df=mdy-all }}</ref> The stereo effect is achieved through differences in sound pressure level between two microphones. A difference in levels of 18&nbsp;dB (16 to 20&nbsp;dB) is needed for hearing the direction of a loudspeaker. Due to the lack of differences in time-of-arrival/phase ambiguities, the sonic characteristic of X-Y recordings has less sense of space and depth when compared to recordings employing an A-B setup. When two figure-eight microphones are used, facing ±45° with respect to the sound source, the X-Y setup is called a [[Blumlein pair]]. The sonic image produced is realistic.
