摘要： A video-audio recording and reproducing apparatus (101) has a built-in stereo microphone (21a, 21b) and an external microphone connection terminal (32). The external microphone connection terminal (32) is connected to a binaural microphone (3) to be attached to the ears of a photographer (300). When the binaural microphone (3) is used to collect ambient sounds, an audio signal to be recorded on a recording medium is switched from an audio signal from the built-in stereo microphone (21a, 21b) to a binaural audio signal from the binaural microphone (3). The photographer (300) puts the binaural microphone (3 (31a, 31b)) on his or her ears and collects ambient sounds around the photographer (300) including a sound emanating from an object. The object is photographed with a camera unit (11). The recording medium records the binaural audio signal, a photographed video signal, and a binaural flag signal.

摘要： In an apparatus for creating an all-around acoustic field, a producing section (4) is composed of a selecting section (41) for selecting one pair of right and left head transfer functions at an angle corresponding to an arriving direction of a reflected sound out of data of head transfer functions in whole directions stored in a storage section (5) on the basis of data of arriving directions of reflected sounds, an equalizing section (42) for equalizing a pair of right and left head transfer functions selected by the selecting section (41) by using frequency characteristic data of reflected sounds, a delaying section (43) for delaying the pair of right and left head transfer functions equalized by the equalizing section (42) by using delay time until a reflected sound arrives at a sound receiving point, and an adding section (44) for obtaining two channels of right and left impulse responses by accumulating the delayed pair of right and left head transfer responses.
