SOUND IMAGE LOCALIZATION PARAMETER CALCULATING DEVICE, SOUND IMAGE LOCALIZATION CONTROL DEVICE, SOUND IMAGE LOCALIZATION DEVICE, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide technology for reducing the working load of a worker to set sound image localization during similar sound image localization in a plurality of different facilities.;SOLUTION: In a reference impulse response data storage region 421 of a computer device 40, data is stored which is measured at a predetermined listening position in a reference facility and which shows the impulse response of each speaker 20-j. In a reference parameter storage region 422, a reference level value and a reference delay time value are stored for localizing sound image which is released from each speaker 20-j in the reference facility. When the impulse response is measured at the listening position in a facility different from the reference facility, a control part 41 calculates a difference between the reference impulse response and the measured impulse response, and calculates a level parameter value and a delay time parameter value to eliminate the difference between the localization position of the sound image in the reference facility and the localization position of the sound image in the facility.;COPYRIGHT: (C)2009,JPO&INPIT
