Title:
SOUND SIGNAL GENERATION DEVICE, SOUND SIGNAL GENERATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2017/056216
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a sound signal generation device capable of improving sound quality of reproduced sound even if reproduced sound volume is small.
In a sound signal generation device (10), from an inputted sound signal (X(t)), a rising edge signal (Edge(t)) indicating the rising edge thereof is generated. An inputted sound signal (X'(t)) and the rising edge signal (Edge(t)) are synthesized according to reproduced sound volume (vol) (19, 14). Preferably, the smaller the reproduced sound volume (vol) is, the larger the synthesis amount of the rising edge signal (Edge(t)) to be synthesized with the sound signal (X'(t)) is made.
