A method of stereo recording where two omnidirectional microphones are placed several feet apart in front of the sound source. This system was used by Harvey Fletcher in 1933 in the first demonstration of stereophonic reproduction of an orchestra. Because the omni pattern will pick up room ambience as well as the desired sound source, mic placement is critical in balancing room sound with direct sound. And, as with any stereo miking technique, phase must also be considered when placing the mics. Spaced omnis are excellent where a natural, “real” sound is desired.
