Patent number: 10728687Abstract: Described herein is a method (30) of rendering an audio signal (17) for playback in an audio environment (27) defined by a target loudspeaker system (23), the audio signal (17) including audio data relating to an audio object and associated position data indicative of an object position. Method (30) includes the initial step (31) of receiving the audio signal (17). At step (32) loudspeaker layout data for the target loudspeaker system (23) is received. At step (33) control data is received that is indicative of a position modification to be applied to the audio object in the audio environment (27). At step (38) in response to the position data, loudspeaker layout data and control data, rendering modification data is generated. Finally, at step (39) the audio signal (17) is rendered with the rendering modification data to output the audio signal (17) with the audio object at a modified object position that is between loudspeakers within the audio environment (27).Type: GrantFiled: April 3, 2019Date of Patent: July 28, 2020Assignees: Dolby Laboratories Licensing Corporation, Dolby International ABInventors: Dirk Jeroen Breebaart, Antonio Mateos Sole, Heiko Purnhagen, Nicolas R.

Publication number: 20200221249Abstract: Diffuse or spatially large audio objects may be identified for special processing. A decorrelation process may be performed on audio signals corresponding to the large audio objects to produce decorrelated large audio object audio signals. These decorrelated large audio object audio signals may be associated with object locations, which may be stationary or time-varying locations. For example, the decorrelated large audio object audio signals may be rendered to virtual or actual speaker locations. The output of such a rendering process may be input to a scene simplification process. The decorrelation, associating and/or scene simplification processes may be performed prior to a process of encoding the audio data.Type: ApplicationFiled: March 17, 2020Publication date: July 9, 2020Applicants: Dolby Laboratories Licensing Corporation, DOLBY INTERNATIONAL ABInventors: Dirk Jeroen BREEBAART, Lie LU, Nicolas R.

Patent number: 10652684Abstract: Multiple virtual source locations may be defined for a volume within which audio objects can move. A set-up process for rendering audio data may involve receiving reproduction speaker location data and pre-computing gain values for each of the virtual sources according to the reproduction speaker location data and each virtual source location. The gain values may be stored and used during “run time,” during which audio reproduction data are rendered for the speakers of the reproduction environment. During run time, for each audio object, contributions from virtual source locations within an area or volume defined by the audio object position data and the audio object size data may be computed. A set of gain values for each output channel of the reproduction environment may be computed based, at least in part, on the computed contributions. Each output channel may correspond to at least one reproduction speaker of the reproduction environment.Type: GrantFiled: February 12, 2018Date of Patent: May 12, 2020Assignees: Dolby Laboratories Licensing Corporation, Dolby International ABInventors: Antonio Mateos Sole, Nicolas R.

Publication number: 20200145779Abstract: Embodiments are described for an adaptive audio system that processes audio data comprising a number of independent monophonic audio streams. One or more of the streams has associated with it metadata that specifies whether the stream is a channel-based or object-based stream. Channel-based streams have rendering information encoded by means of channel name; and the object-based streams have location information encoded through location expressions encoded in the associated metadata. A codec packages the independent audio streams into a single serial bitstream that contains all of the audio data. This configuration allows for the sound to be rendered according to an allocentric frame of reference, in which the rendering location of a sound is based on the characteristics of the playback environment (e.g., room size, shape, etc.) to correspond to the mixer's intent.Type: ApplicationFiled: November 11, 2019Publication date: May 7, 2020Applicant: Dolby Laboratories Licensing CorporationInventors: Charles Q.

Publication number: 20200126568Abstract: Methods for generating an object based audio program which is renderable in a personalizable manner, e.g., to provide an immersive, perception of audio content of the program. Other embodiments include steps of delivering (e.g., broadcasting), decoding, and/or rendering such a program. Rendering of audio objects indicated by the program may provide an immersive experience. The audio content of the program may be indicative of multiple object channels (e.g., object channels indicative of user-selectable and user-configurable objects, and typically also a default set of objects which will be rendered in the absence of a selection by a user) and a bed of speaker channels. Another aspect is an audio processing unit (e.g., encoder or decoder) configured to perform, or which includes a buffer memory which stores at least one frame (or other segment) of an object based audio program (or bitstream thereof) generated in accordance with, any embodiment of the method.Type: ApplicationFiled: December 17, 2019Publication date: April 23, 2020Applicants: DOLBY INTERNATIONAL AB, DOLBY LABORATORIES LICENSING CORPORATIONInventors: Robert Andrew FRANCE, Thomas ZIEGLER, Sripal S.

Patent number: 10623877Abstract: Audio signals are received. The audio signals include left and right surround channels. The audio signals are played back using far-field loudspeakers distributed around a space having a plurality of listener positions. The left and right surround channels are played back by a pair of far-field loudspeakers arranged at opposite sides of the space having the plurality of listener positions. An audio component coinciding with or approximating audio content common to the left and right surround channels is obtained. The audio component is played back using at least a pair of near-field transducers arranged at one of the listener positions. Associated systems, methods and computer program products are provided. Systems, methods and computer program products providing a bitstream comprising the audio signals and the audio component are also provided, as well as a computer-readable medium with data representing such audio content.Type: GrantFiled: April 4, 2019Date of Patent: April 14, 2020Assignee: Dolby Laboratories Licensing CorporationInventors: Remi Audfray, Nicolas R.

Publication number: 20200092668Abstract: Audio perception in local proximity to visual cues is provided. A device includes a video display, first row of audio transducers, and second row of audio transducers. The first and second rows can be vertically disposed above and below the video display. An audio transducer of the first row and an audio transducer of the second row form a column to produce, in concert, an audible signal. The perceived emanation of the audible signal is from a plane of the video display (e.g., a location of a visual cue) by weighing outputs of the audio transducers of the column. In certain embodiments, the audio transducers are spaced farther apart at a periphery for increased fidelity in a center portion of the plane and less fidelity at the periphery.Type: ApplicationFiled: November 19, 2019Publication date: March 19, 2020Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Christophe Chabanne, Nicolas R.
