Title:
ACOUSTIC SIGNAL PROCESSING METHOD, COMPUTER PROGRAM, AND ACOUSTIC SIGNAL PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/014389
Kind Code:
A1
Abstract:
This acoustic signal processing method includes: an acquisition step for acquiring first position information that indicates the position of an object, which is a mobile entity, in a virtual space and second position information that indicates the position of a listener in the virtual space; a first calculation step for calculating the movement speed of the object on the basis of the acquired first position information; a second calculation step for calculating the distance between the object and the listener on the basis of the acquired first position information and the acquired second position information; a generation step for generating an aerodynamic sound signal on the basis of the calculated movement speed and the calculated distance, the aerodynamic sound signal indicating an aerodynamic sound generated as wind produced due to movement of the object reaches the ears of the listener; and an output step for outputting the generated aerodynamic sound signal.
