  • Publication number: 20190222950
    Abstract: Image analysis of a video signal is performed to produce first metadata, and audio analysis of a multi-channel sound track associated with the video signal is performed to produce second metadata. A number of time segments of the sound track are processed, wherein each time segment is processed by either (i) spatial filtering of the audio signals or (ii) spatial rendering of the audio signals, not both, wherein for each time segment a decision was made to select between the spatial filtering or the spatial rendering, in accordance with the first and second metadata. A mix of the processed sound track and the video signal is generated. Other embodiments are also described and claimed.

  • Patent number: 10348781
    Abstract: A method and apparatus for enabling registration of an Aggregate End Point (AEP) device that is incapable of supporting a Session Initiation Protocol (SIP) based Internet Protocol Multimedia Subsystem (IMS) registration are disclosed. The method performs a static registration of the AEP device in a plurality of network elements associated with an Internet Protocol Multimedia Subsystem (IMS) network by provisioning. The method then processes an originating call request or a terminating call request associated with the AEP device using the static registration.

  • Publication number: 20190208347
    Abstract: An audio system that adjusts one or more beam patterns emitted by one or more loudspeaker arrays based on the preferences of users/listeners is described. The audio system includes an audio receiver that contains a listener location estimator, a listener identifier, and a voice command processor. Inputs from the listener location estimator, the listener identifier, and the voice command processor are fed into an array processor. The array processor drives the one or more loudspeaker arrays to emit beam patterns into the listening area based on inputs from each of these devices. By examining the location, preferred usage settings, and voice commands from listeners, the generated beam patterns are customized to the explicit and implicit preferences of the listeners with minimal direct input. Other embodiments are also described.

  • Patent number: 10334355
    Abstract: A loudspeaker array has a cabinet in which is formed a continuously open circumferential horn for controlling sound produced by a number of transducers which are positioned in the cabinet, at a throat of the horn. The continuously open circumferential horn may 1) improve the power efficiency of the transducers without unwanted aliasing effects in audible frequency ranges and 2) provide vertical control for sound emitted by the transducers by flaring.

  • Patent number: 10284951
    Abstract: A method and apparatus for outputting audio based on an orientation of an electronic device, or video shown by the electronic device. The audio may be mapped to a set of speakers using either or both of the device and video orientation to determine which speakers receive certain audio channels.

  • Patent number: 10264383
    Abstract: Some embodiments provide a multi-listener stereo image array which provides multiple separate stereo images of audio content to each of multiple listeners while mitigating interference of audio signals which provide separate stereo images to separate listeners. The array can include sensors which can monitor the environment and can identify relative positions of various listeners and can further control the audio signal patterns generated by the drivers of the array to propagate towards positions associated with particular listeners and be at least partially restricted from propagating towards positions associated with other listeners.

  • Publication number: 20190104366
    Abstract: In a device or method for rendering a sound program for headphones, a location is received for placing the sound program with respect to first and second ear pieces. If the location is between the first ear piece and the second ear piece, the sound program is filtered to produce low-frequency and high-frequency portions. The high-frequency portion is panned according to the location to produce first and second high-frequency signals. The low-frequency portion and the first high-frequency signal are combined to produce a first headphone driver signal to drive the first ear piece. A second headphone driver signal is similarly produced. The sound program may be a stereo sound program. The device or method may also provide for a location that is between the first ear piece and a near-field boundary. Other aspects are also described.

  • Patent number: 10243613
    Abstract: An audio communication system which enables two-way audio communication between at least two users in separate locations includes a talker feedback system which commands a set of audio drivers to generate an acoustical feedback signal which includes at least a portion of an audio input received from the talker to be directed to the talker. The acoustical feedback signal can be generated in response to an intensity of the talker-generated acoustical signal meeting a threshold level, and the feedback can result in causing the talker to reduce the intensity of the talker-generated audio content. The acoustical feedback signal can be directed to a limited portion of the environment in which the talker is located. The talker feedback system can provide at least some of the feedback to the talker via a haptic feedback device.

  • Publication number: 20190082254
    Abstract: A multi-way speaker array is disclosed that includes rings of transducers of different types. The rings of transducers may encircle the cabinet of the speaker array such that the speaker array is rotationally symmetric. The distance between rings of transducers may be based on a logarithmic scale. By separating rings of transducers using logarithmic spacing, denser transducer spacing at short wavelengths is achieved while limiting the number of transducers needed for longer wavelengths by spacing them in larger and larger logarithmic increments. Transducers with overlapping frequency ranges may be used in the speaker array to avoid initial dips or shortfalls in directivity for corresponding beam patterns.

  • Publication number: 20190014434
    Abstract: A directivity adjustment device that maintains a constant direct-to-reverberant ratio based on the detected location of a listener in relation to the speaker array is described. The directivity adjustment device may include a distance estimator, a directivity compensator, and an array processor. The distance estimator detects the distance between the speaker array and the listener. Based on this detected distance, the directivity compensator calculates a directivity index form a beam produced by the speaker array that maintains a predefined direct-to-reverberant sound energy ratio. The array processor receives the calculated directivity index and processes each channel of a piece of sound program content to produce a set of audio signals that drive one or more of the transducers in the speaker array to generate a beam pattern with the calculated directivity index.
