Patent number: 11128978Abstract: 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: November 18, 2016Date of Patent: September 21, 2021Assignees: Dolby Laboratories Licensing Corporation, Dolby International ABInventors: Michael William Mason, Juan Felix Torres, Antonio Mateos Sole, Daniel Arteaga, Adam J. Mills, Mark David deBurgh, Andrew Robert Owen

Patent number: 11082790Abstract: Methods, systems, and computer program products for rending an audio object having an apparent size are disclosed. An audio processing system receives audio panning data including a first grid mapping first virtual sound sources in a space and speaker positions to speaker gains. The first grid specifies first speaker gains of the first virtual sound sources in the space. The audio processing system determines a second grid of second virtual sound sources in the space, including mapping the first virtual sound sources into the second virtual sound sources of the second virtual sources. The audio processing system selects at least one of the first grid or second grid for rendering an audio object based on an apparent size of the audio object. The audio processing system renders the audio object based on the selected grid or grids.Type: GrantFiled: May 1, 2018Date of Patent: August 3, 2021Assignee: Dolby International ABInventors: Daniel Arteaga, Giulio Cengarle, Antonio Mateos Sole

Publication number: 20210219083Abstract: An audio object including audio content and object metadata is received. The object metadata indicates an object spatial position of the audio object to be rendered by audio speakers in a playback environment. Based on the object spatial position and source spatial positions of the audio speakers, initial gain values for the audio speakers are determined. The initial gain values can be used to select a set of audio speakers from among the audio speakers. Based on the object spatial position and a set of source spatial positions at which the set of audio speakers are respectively located in the playback environment, a set of non-negative optimized gain values for the set of audio speakers is determined. The audio object at the object spatial position is rendered with the set of optimized gain values for the set of audio speakers.Type: ApplicationFiled: January 14, 2021Publication date: July 15, 2021Applicants: DOLBY LABORATORIES LICENSING CORPORATION, Dolby International ABInventors: Jun Wang, Giulio Cengarle, Juan Felix Torres, Daniel Arteaga

Publication number: 20200366994Abstract: Embodiments are described for a method of simultaneously localizing a set of speakers and microphones, having only the times of arrival between each of the speakers and microphones. An autodiscovery process uses an external input to set: a global translation (3 continuous parameters), a global rotation (3 continuous parameters), and discrete symmetries, i.e., an exchange of any axis pairs and/or reversal of any axis. Different time of arrival acquisition techniques may be used, such as ultrasonic sweeps or generic multitrack audio content. The autodiscovery algorithm is based in minimizing a certain cost function, and the process allows for latencies in the recordings, possibly linked to the latencies in the emission.Type: ApplicationFiled: August 6, 2020Publication date: November 19, 2020Applicants: Dolby Laboratories Licensing Corporation, Dolby International ABInventors: Daniel ARTEAGA, Giulio CENGARLE, David Matthew FISCHER, Antonio MATEOS SOLE, Davide SCAINI, Alan SEEFELDT
