Patent number: 11778403Abstract: An apparatus and method of generating personalized HRTFs. The system is prepared by calculating a model for HRTFs described as the relationship between a finite example set of input data, namely anthropometric measures and demographic information for a set of individuals, and a corresponding set of output data, namely HRTFs numerically simulated using a high-resolution database of 3D scans of the same set of individuals. At the time of use, the system queries the user for their demographic information, and then from a series of images of the user, the system detects and measures various anthropometric characteristics.

Patent number: 11526273Abstract: User-input obfuscating techniques involving displaying multiple targets on a display device. A visual indication of the current user target moves to a first target at a first time in response to user input, and a first presentation of a visual or audio feedback signal confirming actuation of a target occurs at a second time, without a user input for actuation of a target received while the current user target has remained at the first target from the first time to the second time. The visual indication moves to a second target at a third time in response to user input. The second target is actuated in response to receiving user input for actuation of the current user target after the third time. Then, with the current user target having remained at the second target since the third time, a second presentation of the visual or audio feedback signal is provided.Type: GrantFiled: May 10, 2019Date of Patent: December 13, 2022Assignee: Microsoft Technology Licensing, LLCInventor: Ross Garrett Cutler

Patent number: 11516614Abstract: The invention provides a method for generating output filters to a plurality of loudspeakers at respective positions for playback of a plurality of different input signals in respective spatially different sound zones by means of a processor system. The method comprising computing spatio-temporal correlation matrices in response to spatial information, e.g. measured transfer functions, and in response to desired sound pressures in the plurality of sound zones. Joint eigenvalue decomposition of the spatial correlation matrices are then computed, or at least an approximation thereof, to arrive at eigenvectors accordingly. Next, variable span filters a reformed from a linear combination of the eigenvectors in response to a desired trade-off between acoustic contrast and acoustic errors in the sound zones. Finally, output filter for each of the plurality of loudspeakers, for each of the plurality of input signals, in accordance with the variable span filters.Type: GrantFiled: April 12, 2019Date of Patent: November 29, 2022Assignee: Huawei Technologies Co., Ltd.Inventors: Taewoong Lee, Jesper Kjaer Nielsen, Jesper Rindom Jensen, Mads Graesbøll Christensen

Patent number: 11503419Abstract: A method includes receiving a multi-channel audio signal (101) including multiple input audio channels (102, 104, 106, 108) that are configured to play audio from multiple respective locations relative to a listener. One or more spectral components that undergo a panning effect (1001, 1002, 1003) are identified in the multi-channel audio signal among at least some of the input audio channels. One or more virtual channels (1100, 1200, 1300) are generated, which together with the input audio channels form an extended set (111) of audio channels that retain the identified panning effect. A reduced set (222) of output audio signals, fewer in number than the input audio signals, is generated from the extended set, including recreating the panning effect in the output audio signals. The reduced set of output audio signals is outputted to a user.Type: GrantFiled: June 26, 2019Date of Patent: November 15, 2022Assignee: SPHEREO SOUND LTD.Inventors: Yoav Mor, David Mimouni, Alon Rosenberg, Hagay Konyo

Patent number: 11503424Abstract: An audio processing apparatus comprises a receiver (705) which receives audio data including audio components and render configuration data including audio transducer position data for a set of audio transducers (703). A renderer (707) generating audio transducer signals for the set of audio transducers from the audio data. The renderer (7010) is capable of rendering audio components in accordance with a plurality of rendering modes. A render controller (709) selects the rendering modes for the renderer (707) from the plurality of rendering modes based on the audio transducer position data. The renderer (707) can employ different rendering modes for different subsets of the set of audio transducers the render controller (709) can independently select rendering modes for each of the different subsets of the set of audio transducers (703).Type: GrantFiled: January 14, 2021Date of Patent: November 15, 2022Assignee: Koninklijke Philips N.V.Inventors: Werner Paulus Josephus De Bruijn, Aki Sakari Harma, Arnoldus Werner Johannes Oomen
