Title:
SIGNAL PROCESSING DEVICE AND METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/172053
Kind Code:
A1
Abstract:
The present technology relates to a signal processing device and method, and a program that make it possible to obtain a higher sound quality signal. This signal processing device is provided with: a differential signal generation unit that, on the basis of a prediction coefficient obtained by learning using, as teacher data, a differential signal between a learning re-quantization signal obtained by re-quantizing an original sound signal and the original sound signal, and an input signal, generates the differential signal corresponding to the input signal; and a synthesis unit that synthesizes the generated differential signal and the input signal. The present technology is applicable to signal processing devices.
