Patent number: 8811626Abstract: A recording/reproducing apparatus includes a plurality of unidirectional microphones and a plurality of direction indicator switches. The unidirectional microphones are each disposed in the periphery with a predetermined angle interval therebetween, whereas the direction indicator switches are able to indicate other directions other than a plurality of directions corresponding to the unidirectional microphones. In a normal reproducing mode, a plurality of audio signals which are picked up by the unidirectional microphones and subsequently recorded is read and reproduced in parallel. When any one of the direction indicator switches is operated, only the audio signal emitted in the designated direction is selectively read and reproduced.
