Publication number: 20160241981Abstract: Methods which uses interpolated primitive matrices to decode encoded audio to recover (losslessly) content of a multichannel audio program and/or to recover at least one downmix of such content, and encoding methods for generating such encoded audio. In some embodiments, a decoder performs interpolation on a set of seed primitive matrices to determine interpolated matrices for use in rendering channels of the program. Other aspects are a system or device configured to implement any embodiment of the method.Type: ApplicationFiled: September 26, 2014Publication date: August 18, 2016Applicant: Dolby Laboratories Licensing CorporationInventors: Malcolm James LAW, Vinay MELKOTE, Rhonda WILSON, Simon PLAIN, ANDY JASPAR

Publication number: 20160142844Abstract: An audio playback system generates output signals for multiple channels of acoustic transducers by applying a rendering matrix to data representing the aural content and spatial characteristics of audio objects, so that the resulting sound field creates accurate listener impressions of the spatial characteristics. Matrix coefficients are updated to render moving objects. Discontinuous updates of the rendering matrix coefficients are controlled according to psychoacoustic principles to reduce audible artifacts. The updates may also be managed to control the amount of data needed to perform the updates.Type: ApplicationFiled: June 23, 2014Publication date: May 19, 2016Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Dirk Jeroen Breebaart, David S.

Patent number: 9224400Abstract: The invention relates to downmixing techniques by which output audio signals are obtained from input audio signals partitioned into subgroups. A variable common gain limiting factor is applied to all downmix coefficients that govern the contributions from the input signals in a subgroup. While preserving the proportions between signal values within a subgroup, the invention makes it possible to limit the gain of different input signal subgroups to different extents, so that relatively more perceptible signals can be limited relatively less. It then becomes possible to achieve a consistent dialogue level while transitioning in a less perceptible fashion between signal portions with and without gain limiting. Embodiments of the invention include a method, a mixing system and a computer-program product.Type: GrantFiled: November 10, 2011Date of Patent: December 29, 2015Assignee: Dolby Laboratories Licensing CorporationInventors: Rhonda Wilson, Michael Ward, Steven Venezia, Roger Dressler

Publication number: 20150332680Abstract: Embodiments are directed a method of rendering object-based audio comprising determining an initial spatial position of objects having object audio data and associated metadata, determining a perceptual importance of the objects, and grouping the audio objects into a number of clusters based on the determined perceptual importance of the objects, such that a spatial error caused by moving an object from an initial spatial position to a second spatial position in a cluster is minimized for objects with a relatively high perceptual importance. The perceptual importance is based at least in part by a partial loudness of an object and content semantics of the object.Type: ApplicationFiled: November 25, 2013Publication date: November 19, 2015Applicant: Dolby Laboratories Licensing CorporationInventors: Brett G. CROCKETT, Alan J. SEEFELDT, Nicolas R. TSINGOS, Rhonda WILSON, Dirk Jeroen BREEBAART, Lie LU, Lianwu CHEN

Publication number: 20150146873Abstract: Embodiments are described for a method and system of rendering and playing back spatial audio content using a channel-based format. Spatial audio content that is played back through legacy channel-based equipment is transformed into the appropriate channel-based format resulting in the loss of certain positional information within the audio objects and positional metadata comprising the spatial audio content. To retain this information for use in spatial audio equipment even after the audio content is rendered as channel-based audio, certain metadata generated by the spatial audio processor is incorporated into the channel-based data. The channel-based audio can then be sent to a channel-based audio decoder or a spatial audio decoder. The spatial audio decoder processes the metadata to recover at least some positional information that was lost during the down-mix operation by upmixing the channel-based audio content back to the spatial audio content for optimal playback in a spatial audio environment.Type: ApplicationFiled: June 17, 2013Publication date: May 28, 2015Applicant: Dolby Laboratories Licensing CorporationInventors: Christophe Chabanne, Brett Crockett, Spencer Hooks, Alan Seefeldt, Nicolas R.

Publication number: 20070200904Abstract: Damage is prevented in printing systems by allowing fluid from the printing system's fluid delivery system to expand. In one embodiment, this is accomplished by fluidly connecting a fluid expansion receptacle to the fluid delivery system. The fluid expansion receptacle provides volumetric compliance so that if printing fluid in the system expands, such as due to freezing, the fluid is able to expand into the fluid expansion receptacle and not damage the printing system.Type: ApplicationFiled: February 28, 2006Publication date: August 30, 2007Inventors: Rhonda Wilson, Ronald Ender, Craig Malik

Patent number: 6074050Abstract: Disclosed is a replaceable ink container for providing ink to an ink-jet printing system. The ink container includes a pressure vessel for pressurizing ink. The ink container has a non-operating state and an operating state. Within the operating state, the pressure vessel has an internal gauge pressure maintained within an operating range so that pressurized ink is provided to the printing system. The ink container also includes a gas vent apparatus communicating between an inside surface of the pressure vessel and an outside atmosphere to allow continuous venting in both the operating and non-operating states. In one preferred embodiment the vent apparatus includes a porous member that is located between a pressurized region of the ink container and an outside atmosphere. This porous member provides a flow path for gas therethrough.Type: GrantFiled: December 3, 1997Date of Patent: June 13, 2000Assignee: Hewlett-Packard CompanyInventors: Raul Perez, Rhonda Wilson, Norman E.
