Title:
ACOUSTIC SIGNAL PROCESSING METHOD, INFORMATION GENERATION METHOD, COMPUTER PROGRAM AND ACOUSTIC SIGNAL PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/014390
Kind Code:
A1
Abstract:
This acoustic signal processing method comprises: a first acquisition step for acquiring object information which includes first location information expressing the location of an object in a virtual space, first sound data expressing a first sound caused by the object, and first identification information expressing a processing means for the first sound data, and second location information which expresses the location of the listener; a first calculation step for calculating the distance between the object and the listener on the basis of the first location information included in the acquired object information, and the acquired second location information; a determination step for determining the processing means for processing the first sound data from among a first processing means for performing volume processing corresponding to the calculated distance and a second processing means for performing volume processing corresponding to a distance calculated by a method which differs from that of the first processing means, on the basis of the first identification information included in the acquired object information; a first processing step for processing the first sound data via the determined processing means; and a first output step for outputting the processed first sound data.
