<P>PROBLEM TO BE SOLVED: To achieve both reduced burden of processing and improved accuracy. <P>SOLUTION: A compensation filter processor according to an embodiment comprises impulse response calculation means, factor calculation means and addition means. The impulse response calculation means calculates an impulse response of a regenerating system that consists by including a sound field. The factor calculation means calculates a correction factor for correcting a tap factor that shows weight for each of extracted taps, so that a DC gain has a predetermined value, with respect to FIR (Finite Impulse Response) filters extracted as many as the predetermined number of taps among the FIR filters with inverse of impulse response. The addition means adds the correction factor to each tap factor for each tap included in the extracted FIR filters, and generates a compensation filter for compensating acoustic characteristics of the regenerating system. <P>COPYRIGHT: (C)2012,JPO&INPIT |
