Patent number: 12302082Abstract: Methods for dialogue enhancing audio content, comprising providing a first audio signal presentation of the audio components, providing a second audio signal presentation, receiving a set of dialogue estimation parameters configured to enable estimation of dialogue components from the first audio signal presentation, applying said set of dialogue estimation parameters to said first audio signal presentation, to form a dialogue presentation of the dialogue components; and combining the dialogue presentation with said second audio signal presentation to form a dialogue enhanced audio signal presentation for reproduction on the second audio reproduction system, wherein at least one of said first and second audio signal presentation is a binaural audio signal presentation.Type: GrantFiled: March 15, 2024Date of Patent: May 13, 2025Assignees: Dolby Laboratories Licensing Corporation, DOLBY INTERNATIONAL ABInventors: Leif Jonas Samuelsson, Dirk Jeroen Breebaart, David Matthew Cooper, Jeroen Koppens

Patent number: 12210799Abstract: In an audio encoder, for audio content received in a source audio format, default gains are generated based on a default dynamic range compression (DRC) curve, and non-default gains are generated for a non-default gain profile. Based on the default gains and non-default gains, differential gains are generated. An audio signal comprising the audio content, the default DRC curve, and differential gains is generated. In an audio decoder, the default DRC curve and the differential gains are identified from the audio signal. Default gains are re-generated based on the default DRC curve. Based on the combination of the re-generated default gains and the differential gains, operations are performed on the audio content extracted from the audio signal.Type: GrantFiled: December 11, 2023Date of Patent: January 28, 2025Assignees: DOLBY LABORATORIES LICENSING CORPORATION, DOLBY INTERNATIONAL ABInventors: Jeroen Koppens, Jeffrey Riedmiller, Kristofer Kjoerling, Alexander Stahlmann, Holger Hoerich, Alan J.

Patent number: 12112766Abstract: A method (600) for decoding an encoded audio signal (102) is described. The encoded audio signal (102) comprises a sequence of frames. Furthermore, the encoded audio signal (102) is indicative of a plurality of different dynamic range control (DRC) profiles for a corresponding plurality of different rendering modes. Different subsets of DRC profiles from the plurality of DRC profiles are comprised within different frames of the sequence of frames, such that two or more frames of the sequence of frames jointly comprise the plurality of DRC profiles.Type: GrantFiled: August 14, 2023Date of Patent: October 8, 2024Assignee: DOLBY INTERNATIONAL ABInventors: Holger Hoerich, Jeroen Koppens
