Title:
ACOUSTIC SIGNAL PROCESSING DEVICE AND ACOUSTIC SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/064719
Kind Code:
A1
Abstract:
The acoustic signal processing device of the present disclosure is provided with: a front signal processing unit (101A) for generating a first L signal and a first R signal by means of signal processing of a first signal serving as a front channel signal; a first addition unit (102) for generating, by adding a second signal serving as a left channel signal and the first L signal, a fourth signal to be used as the left channel signal; and a second addition unit (103) for generating, by adding a third signal serving as a right channel signal and the first R signal, a fifth signal to be used as the right channel signal. The front signal processing unit (101A) generates the first L signal and the first R signal by carrying out signal processing in such a manner that the first signal is split and localized to predetermined positions when the first signal is a dialogue signal, or the first signal is split and localized to different positions from the predetermined positions when the first signal is not a dialogue signal.
