Abstract
A coefficient compensating unitcalculates based on a loop point and a cross-fade point of impulse response coefficient data renewed compensation impulse response coefficients specified for a cross-fade period defined between the cross-fade point and an end point of the impulse response coefficient data, and stores the calculated impulse response coefficients in a compensation coefficient memory, wherein the cross-fade point corresponds to a beginning point of the cross-fade period in which a cross-fading is performed to smoothly connect the end point with the loop point. A product-sum operation unitreads audio signal data from an audio signal bufferand reads from the compensation coefficient memoryimpulse response data including the compensated impulse response coefficients specified for the cross-fade period, and multiplies the audio signal data by appropriate impulse response coefficients to obtain multiplication data and accumulates the multiplication data, outputting the accumulated data.
