<P>PROBLEM TO BE SOLVED: To provide an audio device capable of easily generating correction data in a simple process, a correction data generation method and a correction data generation program. <P>SOLUTION: Measured sound, based on prescribed output data OPa outputted from a speaker PKa in the indoor space of an automobile, is acquired as driver seat measurement data L1a at a prescribed driver seat listening point LP1, and driver seat correction data CR1a for correcting the sound field characteristics of the driver seat listening point LP1 are generated, on the basis of a difference between the output data OPa and the driver seat measurement data L1a. It is inferred that the sound field characteristics of a passenger seat listening point LP2 at a position symmetrical to the driver seat listening point LP1 are symmetrical with respect to those of the driver seat listening point LP1, and the driver seat correction data CR1a are used as passenger seat correction data CR2b so as to correct the sound field characteristics of the passenger seat listening point LP2. <P>COPYRIGHT: (C)2007,JPO&INPIT |
