A recorder receives designation of a video which is desired to be reproduced from a user. If designation of one or more designated locations where sound is emphasized on a screen of a display which displays the video is received by the recorder from the user via an operation unit during reproduction or temporary stopping of the video, a signal processing unit performs an emphasis process on audio data, that is, the signal processing unit emphasizes audio data in directions directed toward positions corresponding to the designated locations from a microphone array by using audio data recorded in the recorder. A reproducing device reproduces the emphasis-processed audio data and video data in synchronization with each other.

Sound processing system and processing method that emphasize sound from position designated in displayed video image

A voice conference apparatus includes a sound collecting unit and a loudspeaker, while the sound collecting unit has a directional polar sensitivity characteristic which has a higher sensitivity with respect to sounds which are radiated from at least one direction, as compared with sounds radiated from other directions. The sound collecting unit of the voice conference apparatus has a plurality of omnidirectional microphones, and forms a desirable sensitivity characteristic. Since the omnidirectional microphones are employed, aging changes and fluctuations contained in the sensitivity characteristics of the respective sound collecting units can be reduced, so that the sensitivity characteristics thereof can become stable, and thus, full duplex communications with higher qualities can be carried out.
