PURPOSE:To design a transfer function correction filter where an excellent sound reproduction becomes possible even in general indoor space where reproduced sound space has reverberation. CONSTITUTION:In a step 101, the impulse responses h00 to h11 supplied from a transfer characteristic measuring device 10 are read. Next, the step is shifted to a step 102, a processing correcting the impulse responses h00 to h11 by using a prescribed window function is performed, and the correction impulse responses h00' to h11' are calculated. Based on the correction impulse responses h00' to h11' the filter factor of the transfer function correction filter is calculated in the processings in and after a step 103. |
