DYNAMIC RANGE ADJUSTMENT DEVICE, DYNAMIC RANGE ADJUSTMENT METHOD AND DYNAMIC RANGE ADJUSTMENT PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a dynamic range adjustment device, a dynamic range adjustment method and a dynamic range adjustment program that enable a dynamic range of an acoustic signal to be easily adjusted in multiple ways.;SOLUTION: A correspondence acquisition unit 143 acquires correspondence between change in value of operation parameters OP1, OP2 and OP3 and change in value of a plurality of internal parameters P1-P56. An operation parameter acquisition unit 141 acquires values of the operation parameters OP1, OP2 and OP3. An internal parameter determination unit 142 determines, based upon the correspondence, values of the plurality of internal parameters P1-P56 corresponding to the values of the operation parameters OP1, OP2 and OP3, respectively. A plurality of dynamics processing units 101-105 are connected between an input terminal IN and an output terminal OUT, and adjusts, based upon the values of the internal parameters P1-P50, a dynamic range of an acoustic signal AS1.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
