Publication number: 20240103801Abstract: Embodiments are directed to a method and system for receiving, in a bitstream, metadata associated with the audio data, and analyzing the metadata to determine whether a loudness parameter for a first group of audio playback devices are available in the bitstream. Responsive to determining that the parameters are present for the first group, the system uses the parameters and audio data to render audio. Responsive to determining that the loudness parameters are not present for the first group, the system analyzes one or more characteristics of the first group, and determines the parameter based on the one or more characteristics.Type: ApplicationFiled: October 9, 2023Publication date: March 28, 2024Applicants: DOLBY LABORATORIES LICENSING CORPORATION, DOLBY INTERNATIONAL ABInventors: Jeffrey RIEDMILLER, Scott Gregory NORCROSS, Karl Jonas ROEDEN

Publication number: 20230188918Abstract: Audio content coded for a reference speaker configuration is downmixed to downmix audio content coded for a specific speaker configuration. One or more gain adjustments are performed on individual portions of the downmix audio content coded for the specific speaker configuration. Loudness measurements are then performed on the individual portions of the downmix audio content. An audio signal that comprises the audio content coded for the reference speaker configuration and downmix loudness metadata is generated. The downmix loudness metadata is created based at least in part on the loudness measurements on the individual portions of the downmix audio content.Type: ApplicationFiled: December 19, 2022Publication date: June 15, 2023Applicants: Dolby Laboratories Licensing Corporation, DOLBY INTERNATIONAL ABInventors: Michael C.

Patent number: 11330370Abstract: Audio data in a first format may be processed to produce audio data in a second format, which may be a reduced or simplified version of the first format. A loudness correction process may produce loudness-corrected audio data in the second format. A first power of the audio data in the second format and a second power of the loudness-corrected audio data in the second format may be determined. A second-format loudness correction factor for the audio data in the second format may be based, at least in part, on a power ratio between the first power and the second power. A first-format loudness correction factor for the audio data in the first format may be based, at least in part, on the power ratio and a power relationship between the audio data in the first format and the audio data in the second format.Type: GrantFiled: February 15, 2019Date of Patent: May 10, 2022Assignee: Dolby Laboratories Licensing CorporationInventors: Scott Gregory Norcross, Michael Grant, James Stuart Cowdery, Sachin Nanda, Nisarg Vipul Shah

Patent number: 11075762Abstract: The present document relates to transcoding of metadata, and in particular to a method and system for transcoding metadata with reduced computational complexity. A transcoder configured to transcode an inbound bitstream comprising an inbound content frame and an associated inbound metadata frame into an outbound bitstream comprising an outbound content frame and an associated outbound metadata frame is described. The inbound content frame is indicative of a signal encoded according to a first codec system and the outbound content frame is indicative of the signal encoded according to a second codec system. The transcoder is configured to identify an inbound block of metadata from the inbound metadata frame, the inbound block of metadata associated with an inbound descriptor indicative of one or more properties of metadata comprised within the inbound block of metadata, and to generate the outbound metadata frame from the inbound metadata frame based on the inbound descriptor.Type: GrantFiled: December 17, 2019Date of Patent: July 27, 2021Assignees: Dolby Laboratories Licensing Corporation, Dolby International ABInventors: Andreas Schneider, Christof Fersch, Martin Wolters, Jeffrey Riedmiller, Scott Gregory Norcross, Michael Grant
