Title:
VOICE SIGNAL PROCESSING DEVICE, VOICE SIGNAL PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/030172
Kind Code:
A1
Abstract:
This voice signal processing device (100) comprises: a first input terminal (112a) which receives a voice signal from a record player (10); a memory (102) which stores correction parameters for voice signal processing and characteristic information indicating the characteristics of a voice signal for measurement; a signal processing circuit (101) which performs the voice signal processing on the received voice signal on the basis of the correction parameter; and a microcomputer (108), wherein the microcomputer (108) measures acoustic characteristics of a voice signal received when the voice signal for measurement recorded in a record disk for measurement is played back, generates the correction parameters on the basis of a result of comparison between the measurement result and the characteristic information, and stores, in the memory (102), setting information indicating the setting pertaining to the voice signal processing when the measurement is executed in association with the generated correction parameter.
