ABSTRACT:
An external memory control circuit for a sound field processing digital signal processor capable of obtaining continuous sound listening by shortening the time that sound is cut off upon a change of the sound field algorithm depending on the listening place (i.e., concert hall, meeting hall, church or the like). The external memory control circuit is constructed to utilize a mute function only for the time required to transfer the algorithm itself where a sound field processing circuit is realized using a DSP, thereby reducing the time that sound is cut off and thereby obtaining continuous sound listening even when the sound field algorithm is changed while listening.
