Patent number: 11937074Abstract: The present document relates to methods and apparatus for rendering input audio for playback in a playback environment. The input audio includes at least one audio object and associated metadata, and the associated metadata indicates at least a location of the audio object. A method for rendering input audio including divergence metadata for playback in a playback environment comprises creating two additional audio objects associated with the audio object such that respective locations of the two additional audio objects are evenly spaced from the location of the audio object, on opposite sides of the location of the audio object when seen from an intended listener's position in the playback environment, determining respective weight factors for application to the audio object and the two additional audio objects, and rendering the audio object and the two additional audio objects to one or more speaker feeds in accordance with the determined weight factors.Type: GrantFiled: January 28, 2021Date of Patent: March 19, 2024Assignees: Dolby Laboratories Licensing Corporation, Dolby International ABInventors: Michael William Mason, Juan Felix Torres, Antonio Mateos Sole, Daniel Arteaga, Adam J.

Publication number: 20230267945Abstract: Described is a method of performing automatic audio enhancement on an input audio signal including at least one speech-articulation noise event. The method comprises: segmenting the input audio signal into a number of audio frames; obtaining at least one feature parameter from the audio frames; and determining, based at least in part on the obtained feature parameter, a respective type of the speech-articulation noise event and a respective time-frequency range associated with the speech-articulation noise event within the input audio signal.Type: ApplicationFiled: August 11, 2021Publication date: August 24, 2023Applicant: DOLBY INTERNATIONAL ABInventors: Chunghsin YEH, Giulio CENGARLE, Mark David DE BURGH

Publication number: 20220322004Abstract: Methods for performing dynamic range compression (DRC) on audio in a manner intended to produce output audio for playback by systems or devices with limited power handling capabilities and preferably also to reduce or prevent undesirable artifacts (e.g., pumping and/or breathing) in the output audio. Some embodiments perform the DRC so as to maximize average loudness (while preventing loss of quieter elements) during playback, and also to reduce or prevent distortion. Other aspects are systems or devices configured to perform embodiments of the method. In some embodiments, reduced DRC is applied when average loudness of the input audio approaches (or matches or exceeds) a target (e.g., a knee point for DRC, or a signal level near to a maximum playback level of the intended playback system), since such input audio is assumed to have already been compressed, and otherwise applying full DRC to the input audio.Type: ApplicationFiled: September 10, 2020Publication date: October 6, 2022Applicant: Dolby Laboratories Licensing CorporationInventors: Mark David DE BURGH, Ning WANG

Patent number: 10530319Abstract: A method in a computing device configured to perform volume-levelling processing on input audio data by at least applying one or more filters to the input audio data, the computing device being configured to obtain an estimated difference between a target output loudness level and a loudness level associated with the input audio data, and to adapt the filter coefficients of the one or more filters based on the estimated difference. The method involves starting, or stopping, the volume-levelling processing. The method comprises gradually increasing, or decreasing, a weighting applied to the estimated difference, in response to obtaining an indication to start, or stop, the volume-levelling processing.Type: GrantFiled: August 17, 2016Date of Patent: January 7, 2020Assignee: Dolby Laboratories Licensing CorporationInventor: Mark David De Burgh

Publication number: 20190387346Abstract: Systems, methods, and computer program products of preparing an audio signal for playback on a monaural playback device A system receives an audio signal including one or more components, the one or more components including sound from one or more audio sources. The system processes the audio signal to create a monaural signal. The processing includes introducing one or more monaural cues into at least one component of the one or more components. The monaural signal maintains a presence of the one or more monaural cues. The system then provides the monaural signal to the monaural playback device or to a storage device. The one or more monaural cues are such that, if the monaural signal is played back to a listener using the monaural playback device, the listener experiences a perceived differentiation in direction of the one or more components and/or the one or more audio sources.Type: ApplicationFiled: June 13, 2019Publication date: December 19, 2019Applicant: Dolby Laboratories Licensing CorporationInventors: Mark David DE BURGH, Timothy Alan PORT, David Matthew COOPER

Patent number: 10136240Abstract: Methods a provided for improving an audio scene for people suffering from hearing loss or for adverse hearing environments. Audio objects may be prioritized. In some implementations, audio objects that correspond to dialog may be assigned to a highest priority level. Other implementations may involve assigning the highest priority to other types of audio objects, such as audio objects that correspond to events. During a process of dynamic range compression, higher-priority objects may be boosted more, or cut less, than lower-priority objects. Some lower-priority audio objects may fall below the threshold of human hearing, in which case the audio objects may be dropped and not rendered.Type: GrantFiled: April 19, 2016Date of Patent: November 20, 2018Assignee: Dolby Laboratories Licensing CorporationInventors: Mark David De Burgh, Tet Fei Yap
