Publication number: 20240105186Abstract: A method for encoding an input audio stream including the steps of obtaining a first playback stream presentation of the input audio stream intended for reproduction on a first audio reproduction system, obtaining a second playback stream presentation of the input audio stream intended for reproduction on a second audio reproduction system, determining a set of transform parameters suitable for transforming an intermediate playback stream presentation to an approximation of the second playback stream presentation, wherein the transform parameters are determined by minimization of a measure of a difference between the approximation of the second playback stream presentation and the second playback stream presentation, and encoding the first playback stream presentation and the set of transform parameters for transmission to a decoder.Type: ApplicationFiled: October 16, 2023Publication date: March 28, 2024Applicants: DOLBY LABORATORIES LICENSING CORPORATION, DOLBY INTERNATIONAL ABInventors: Dirk Jeroen Breebaart, David Matthew Cooper, Leif Jonas Samuelsson, Jeroen Koppens, Rhonda J. Wilson, Heiko Purnhagen, Alexander Stahlmann

Publication number: 20240071411Abstract: Disclosed is a method for determining one or more dialog quality metrics of a mixed audio signal comprising a dialog component and a noise component, the method comprising separating an estimated dialog component from the mixed audio signal by means of a dialog separator using a dialog separating model determined by training the dialog separator based on the one or more quality metrics; providing the estimated dialog component from the dialog separator to a quality metrics estimator; and determining the one or more quality metrics by means of the quality metrics estimator based on the mixed signal and the estimated dialog component. Further disclosed is a method for training a dialog separator, a system comprising circuitry configured to perform the method, and a non-transitory computer-readable storage medium.Type: ApplicationFiled: January 4, 2022Publication date: February 29, 2024Applicant: Dolby Laboratories Licensing CorporationInventors: Jundai SUN, Lie LU, Shaofan YANG, Rhonda J.

Publication number: 20220366919Abstract: Encoding/decoding techniques where multiple transform parameter sets are encoded together with a rendered playback presentation of an input audio content. The multiple transform parameters are used on the decoder side to transform the playback presentation to provide a personalized binaural playback presentation optimized for an individual listener with respect to their hearing profile. This may be achieved by selection or combination of the data present in the metadata streams.Type: ApplicationFiled: September 22, 2020Publication date: November 17, 2022Applicant: Dolby Laboratories Licensing CorporationInventors: DIRK JEROEN BREEBAART, ALEX BRANDMEYER, POPPY ANNE CARRIE CRUM, JOYNER STEELE MCGREGOR, David MCGRATH, Andrea FANELLI, Rhonda J. WILSON

Publication number: 20220295207Abstract: A method for generating mastered audio content, the method comprising obtaining an input audio content comprising a number, M1, of audio signals, obtaining rendered presentation of the input audio content, the rendered presentation comprising a number, M2, of audio signals, obtaining a mastered presentation generated by mastering the rendered presentation, comparing the mastered presentation with the rendered presentation to determine one or more indications of differences between the mastered presentation and the rendered presentation, modifying one or more of the audio signals of the input audio content based on the indications of differences to generate the mastered audio content. With this approach, conventional, typically stereo, channel-based mastering tools can be used to provide a mastered version of any input audio content, including object-based immersive audio content.Type: ApplicationFiled: July 7, 2020Publication date: September 15, 2022Applicant: Dolby Laboratories Licensing CorporationInventors: Dirk Jeroen BREEBAART, David Matthew COOPER, Giulio CENGARLE, Brett G. CROCKETT, Rhonda J. WILSON

Patent number: 11284184Abstract: A method of calibrating a feedback-based noise cancellation system of an ear device may involve obtaining a measured plant response of the ear device, obtaining a reference plant response value and determining a plant response variation between the reference plant response value and a value corresponding to the measured plant response. The method may involve obtaining a measured a coupler response of the ear device, obtaining a reference coupler response value and determining a coupler response variation between the reference coupler response value and a value corresponding to the measured coupler response. The method may involve determining, based at least in part on the plant response variation and the coupler response variation, a microphone signal gain correction factor and applying the microphone signal gain correction factor to ear device microphone signals that are input to a feedback loop of the feedback-based noise cancellation system.Type: GrantFiled: July 29, 2019Date of Patent: March 22, 2022Assignee: Dolby Laboratories Licensing CorporationInventors: Matthew Conrad Fellers, Louis D. Fielder, Douglas Walter Hansen, Joshua B. Lando, C. Phillip Brown, Rhonda J. Wilson
