MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202548022223 A) filed by Dolby International Ab on March 12, 2025, for Methods, Apparatus And Systems For A Pre-Rendered Signal For Audio Rendering.

Inventors include Terentiv, Leon; Fersch, Christof; and Fischer, Daniel Number.

The application for the patent was published on July 10, 2026, under issue no. 28/2026.

Abstract: ABSTRACT METHODS, APPARATUS AND SYSTEMS FOR A PRE-RENDERED SIGNAL FOR AUDIO RENDERING 5 The present disclosure relates to a method of decoding audio scene content from a bitstream by a decoder that includes an audio renderer with one or more rendering tools. The method comprises receiving the bitstream, decoding a description of an audio scene from the bitstream, determining one or more effective audio elements from the description of the audio scene, determining effective audio element information indicative of effective audio element positions 10 of the one or more effective audio elements from the description of the audio scene, decoding a rendering mode indication from the bitstream, wherein the rendering mode indication is indicative of whether the one or more effective audio elements represent a sound field obtained from pre-rendered audio elements and should be rendered using a predetermined rendering mode, and in response to the rendering mode indication indicating that the one or more effective 15 audio elements represent the sound field obtained from pre-rendered audio elements and should be rendered using the predetermined rendering mode, rendering the one or more effective audio elements using the predetermined rendering mode, wherein rendering the one or more effective audio elements using the predetermined rendering mode takes into account the effective audio element information, and wherein the predetermined rendering mode defines a predetermined 20 configuration of the rendering tools for controlling an impact of an acoustic environment of the audio scene on the rendering output. The disclosure further relates to a method of generating audio scene content and a method of encoding audio scene content into a bitstream.
