Patent number: 11386913Abstract: Methods (700, 800, 900), systems (200, 300, 400, 500, 600) and computer program products are provided. Location metadata (620) associated with an audio object is received (801). The location metadata defines a position of the audio object in an audio scene. It is estimated (630, 802), based on the location metadata, whether the audio object includes dialog. A value representative of a result of the estimation is assigned (803) to an object type parameter (231). In some example embodiments, audio objects are selected (661, 662, 804) based on values of their respective of object type parameters. In some example embodiments, at least one of the selected audio objects is submitted to dialog enhancement (690, 807).Type: GrantFiled: July 26, 2018Date of Patent: July 12, 2022Assignee: Dolby Laboratories Licensing CorporationInventor: Mark William Gerrard

Publication number: 20220059102Abstract: A method of encoding audio content comprises performing a content analysis of the audio content, generating classification information indicative of a content type of the audio content based on the content analysis, encoding the audio content and the classification information in a bitstream, and outputting the bitstream. A method of decoding audio content from a bitstream including audio content and classification information for the audio content, wherein the classification information is indicative of a content classification of the audio content, comprises receiving the bitstream, decoding the audio content and the classification information, and selecting, based on the classification information, a post processing mode for performing post processing of the decoded audio content. Selecting the post processing mode can involve calculating one or more control weights for post processing of the decoded audio content based on the classification information.Type: ApplicationFiled: December 10, 2019Publication date: February 24, 2022Applicants: DOLBY LABORATORIES LICENSING CORPORATION, DOLBY INTERNATIONAL ABInventors: Yanning Bai, Mark William Gerrard, Richard Han, Martin Wolters

Patent number: 11238883Abstract: A method and a system for dialogue enhancement of an audio signal, comprising receiving (step S1) the audio signal and a text content associated with dialogue occurring in the audio signal, generating (step S2) parameterized synthesized speech from the text content, and applying (step S3) dialogue enhancement to the audio signal based on the parameterized synthesized speech. With the invention text captions, subtitles, or other forms of text content included in an audio stream, can be used to significantly improve dialogue enhancement on the playback side.Type: GrantFiled: May 23, 2019Date of Patent: February 1, 2022Assignee: Dolby Laboratories Licensing CorporationInventors: Timothy Alan Port, Winston Chi Wai Ng, Mark William Gerrard

Patent number: 10582327Abstract: Systems and methods are described for providing an immersive listening area for one or more listeners. To improve the immersive experience a rear sound bar is placed behind the listeners and the input channels of the rear sound bar receive customized processing to create a virtual rear sound stage. The virtual rear sound stage and a front sound stage created by a front sound bar, combine to create an overall sound stage to encompass the listeners, providing the listeners with an immersive listening experience.Type: GrantFiled: October 11, 2018Date of Patent: March 3, 2020Assignee: Dolby Laboratories Licensing CorporationInventors: Mark William Gerrard, Michael William Mason
