PROBLEM TO BE SOLVED: To perform correction processing without increasing noises even in the case where a frequency band becomes different in accordance with the type of a sound source when simultaneously reproducing two different sound sources within a compartment, and to more effectively cancel influences of the other sound source in the case where priorities are set.SOLUTION: On the basis of sound source analysis information supplied from frequency analysis means 104, 105 for analyzing two types of sound sources to be reproduced within a vehicle, sound source type information supplied from sound source type analysis means 106 for analyzing the two sound source types and priorities supplied from user side priority setting means 103 for setting priorities by a user, correction characteristics are calculated by correction characteristic calculating means 107 and the correction characteristics are set in front-seat correction characteristic setting means 108 and rear-seat correction characteristic setting means 109. Therefore, correction characteristics suitable for a front-seat sound source and a rear-seat sound source, respectively, are added and outputted. |
