US 2024/0267696 A1 · Apparatus, Method and Computer Program for Synthesizing a Spatially Extended Sound Source Using Elementary Spatial Sectors

Abstract

An apparatus for synthesizing a spatially extended sound source (SESS), has: a storage for storing rendering data items for different elementary spatial sectors covering a rendering range for a listener; a sector identification processor for identifying, from the different elementary spatial sectors, a set of elementary spatial sectors belonging to the spatially extended sound source based on listener data and spatially extended sound source data; a target data calculator for calculating target rendering data from the rendering data items for the set of elementary spatial sectors; and an audio processor for processing an audio signal representing the spatially extended sound source using the target rendering data.
