Abstract
A sound field compensating apparatus is provided in which delay data produced by one of the delay means in a FIR filter, which is realized by the action of a DSP, is commonly used for producing a plurality of reflected sound data of corresponding channels. Accordingly, the maximum delay time of the delay data is lengthened without increasing the number of delay data retrieving actions per sampling period on the delay memory. Hence, an acceptable number of the reflected sound signals can be obtained for each channel.
