PURPOSE:To vary the sound field continuously in real time by storing a processing procedure required to apply continuous sound field control into a processing command means in advance and having only to send a code for selecting the processing procedure from a system control means. CONSTITUTION:The device consists of an input means 1, a 1st signal processing means 2, a 1st processing command means 3, a 2nd signal processing means 4, a 2nd processing command means 5, a signal switching means 6, a system control means 7 and a signal output means 8. Then the two signal processing means 2, 4 and the two processing command means 3, 5 are in use and the processing procedure to apply continuous sound field control is stored in advance in the processing command means 2, 5 and a code for the processing procedure selection has only to be sent from the system control means 7 at sound field data switching. Thus, the quick change in the sound field is smoothed and such processing as sound field movement, sense of distance, sense of spread and movement of sound image are realized continuously in real time. |
