ABSTRACT:
For one of memory divisions that is selected at a time as a selected division N(m) in a memory for use in putting a sound processing device in operation of generating a three-dimensional image of an acoustic field, a difference signal is produced to represent a clock count minus a delay count n(m) specific to the selected division and to have more and less significant bits. For use as an address signal supplied to the memory, a part of the more significant bits is changed to a like part of a memory space address specific to the selected division. As usual, the less significant bits are used to indicate read aR(i(m)) and write W(i(m)) pointers which are spaced in the selected division by the delay count. The part may be specified to be wide and narrow when the selected division is narrow and wide. Alternatively, the part may have a predetermined bit width.
