  • Patent number: 10657974
    Abstract: In general, techniques are described by which to provide priority information for higher order ambisonic (HOA) audio data. A device comprising a memory and a processor may perform the techniques. The memory stores HOA coefficients of the HOA audio data, the HOA coefficients representative of a soundfield. The processor may decompose the HOA coefficients into a sound component and a corresponding spatial component, the corresponding spatial component defining shape, width, and directions of the sound component, and the corresponding spatial component defined in a spherical harmonic domain. The processor may also determine, based on one or more of the sound component and the corresponding spatial component, priority information indicative of a priority of the sound component relative to other sound components of the soundfield, and specify, in a data object representative of a compressed version of the HOA audio data, the sound component and the priority information.

  • Patent number: 10524075
    Abstract: The present technology relates to a sound processing apparatus, a method, and a program that can reproduce an acoustic field more appropriately. A sound source position correction unit corrects sound source position information indicating a position of each object sound source, on the basis of a hearing position of a sound, and derives corrected sound source position information. A reproduction area control unit calculates, on a basis of an object sound source signal of a sound of an object sound source, the hearing position, and corrected sound source position information obtained by the correction, a spatial frequency spectrum such that a reproduction area is adjusted in accordance with the hearing position provided inside a spherical or annular speaker array. The present technology can be applied to a sound processing apparatus.

  • Patent number: 10504529
    Abstract: A method and apparatus for providing binaural audio for a headset is provided. In one embodiment, a method includes encoding audio signals to provide binaural audio to a headset. The method includes receiving audio signals from a microphone array comprising a first plurality of elements and applying far-field array processing to the audio signals to generate a first plurality of channels. The channels can be beam channels and each channel is associated with a particular beam angle. The method further includes selecting a second plurality of channels from the first plurality of channels that is a subset of the first plurality of channels. The method includes encoding the audio signals from the selected second plurality of channels with information associated with the particular beam angle for each of the selected second plurality of channels. The encoded audio signals are configured to provide binaural audio to a headset.

  • Patent number: 10496360
    Abstract: A method displays an emoji that enables a user to select how or where sound will localize to a listener of the sound associated with the emoji. During an electronic communication between a first user and a second user, the first user selects how or where sound of the emoji will localize to the second user. When the second user receives the emoji, the sound plays to the second user how or where as selected by the first user.

  • Patent number: 10499177
    Abstract: A system and method for applying an individual volume control setting to individual sound zones as set by a user. When the individual volume control setting differs from a master volume control setting, the individual volume control setting is applied to the low frequency component of the audio signal. Headrest and optional height speakers for each individual sound zone's independent volume setting are applied to the mid and high frequency components of the audio signal.

  • Patent number: 10497346
    Abstract: A multimodal system and process processed one or more sensor signals and extracts features from the one or more sensor signals through a spatiotemporal correlation between consecutive frames of an image or video sequence. The multimodal system and process determines the movement and direction of the features through an image subtraction, or a coherence measure and synthesizes a musical instrument signal in response to the detected movement and direction or the triggers. The imaginary musical instrument signal is added to an infotainment signal within a vehicle.

  • Patent number: 10490205
    Abstract: Systems and methods are described for storing and reusing previously generated/calculated acoustic environment data. By reusing acoustic environment data, the systems and methods described herein may avoid the increased overhead in generating/calculating acoustic environment data for a location when this data has already been generated and is likely accurate. In particular, the time and complexity involved in determining reverberation/echo levels, noise levels, and noise types may be avoided when this information is available in storage. This previously stored acoustic environment data may not be limited to data generated/calculated by the same audio device. Instead, in some embodiments an audio device may access a centralized repository to leverage acoustic environment data generated/calculated by other audio devices.
