Departing slightly from the notion of capsule coincidence, a number of dual-microphone
mounting techniques have been developed for stereo recording and are embodied in
acoustically appropriate structures. Most of these are spherical, some purposely head-shaped,
while others are merely some kind of baffle with microphones on opposite sides. Althoughmost
of these embodiments work well enough for direct stereo pickup, some may be more suited to
the requirements of binaural recording.
