  • Publication number: 20180020310
    Abstract: Embodiments are described for rendering spatial audio content through a system that is configured to reflect audio off of one or more surfaces of a listening environment. The system includes an array of audio drivers distributed around a room, wherein at least one driver of the array of drivers is configured to project sound waves toward one or more surfaces of the listening environment for reflection to a listening area within the listening environment and a renderer configured to receive and process audio streams and one or more metadata sets that are associated with each of the audio streams and that specify a playback location in the listening environment.

  • Publication number: 20170310767
    Abstract: An M2M Service Layer is expanded to access the services of third parties and exchange data with these third parties. The M2M Service Layer is then able to act as a proxy between M2M Devices and the third party services. The M2M Service Layer is able to present a single/consistent interface, or API, to the M2M Device and hide the details of the third party service provider from the M2M Device.

  • Patent number: 9794716
    Abstract: An audio processing system, such as an upmixer, may be capable of separating diffuse and non-diffuse portions of N input audio signals. The upmixer may be capable of detecting instances of transient audio signal conditions. During instances of transient audio signal conditions, the up-mixer may be capable of adding a signal-adaptive control to a diffuse signal expansion process in which M audio signals are output. The upmixer may vary the diffuse signal expansion process over time such that during instances of transient audio signal conditions the diffuse portions of audio signals may be distributed substantially only to output channels spatially close to the input channels. During instances of non-transient audio signal conditions, the diffuse portions of audio signals may be distributed in a substantially uniform manner.

  • Publication number: 20170208392
    Abstract: Embodiments are directed to a virtual height filter for use with or in an upward-firing speaker system that reflects sound off a ceiling to a listening location at a distance from a speaker, and that provides height cues to reproduce audio objects that have overhead audio components. A virtual height filter based on a directional hearing model is applied to the upward-firing driver signal to improve the perception of height for audio signals transmitted by the virtual height speaker to provide optimum reproduction of the overhead reflected sound. The virtual height filter is provided by any one or combination of analog or digital filter circuits, or mechanical structures including speaker grill, enclosure, or driver design or configuration.

  • Patent number: 9648440
    Abstract: Embodiments are directed to speakers and circuits that reflect sound off a ceiling to a listening location at a distance from a speaker. The reflected sound provides height cues to reproduce audio objects that have overhead audio components. The speaker comprises upward firing drivers to reflect sound off of the upper surface and represents a virtual height speaker. A virtual height filter based on a directional hearing model is applied to the upward-firing driver signal to improve the perception of height for audio signals transmitted by the virtual height speaker to provide optimum reproduction of the overhead reflected sound. The virtual height filter may be incorporated as part of a crossover circuit that separates the full band and sends high frequency sound to the upward-firing driver.

  • Publication number: 20170103771
    Abstract: Example embodiments disclosed herein relate to noise level estimation. A method for noise level estimation is disclosed. The method includes, responsive to an increase of a signal level of a noise signal, calculating an impulsive noise probability of the noise signal, the impulsive noise probability indicating a likelihood that the noise signal is an impulsive noise. The method also includes determining a variable smoothing factor for noise level estimation based on the impulsive noise probability, the variable smoothing factor being associated with a previous estimated level of the noise signal. The method further includes smoothing the noise signal with the variable smoothing factor so as to determine a current estimated level of the noise signal. Corresponding system and computer program products are also disclosed.

  • Publication number: 20170099554
    Abstract: Example embodiments disclosed herein relate to modelling a frequency response characteristic of an electro-acoustic transducer. A method includes obtaining at least one measurement of the frequency response characteristic for at least one electro-acoustic transducer of the category. A model of a frequency response characteristic specific to a category of electro-acoustic transducers is generated at least in part based on perceptual importance of a frequency band, an averaged, normalized or microphone compensated measurement such that the distortion of the model is optimized. A further method for estimating a frequency response characteristic of an electro-acoustic transducer is based on the generated model and the sensitivity of the electro-acoustic transducer or headphone. Corresponding system and computer program product are also disclosed.

  • Publication number: 20170026750
    Abstract: Embodiments are directed to speakers and circuits that reflect sound off a wall surface (114) to a listening location at a distance from a speaker. The reflected sound (103) provides direct audio cues to reproduce audio objects that have direct audio components without the need for direct firing speakers. The speaker comprises sideward firing drivers (108) to reflect sound off of the wall surface (114) and represents a virtual direct speaker (116). A virtual direct filter is applied to the sideward-firing driver signal to improve the perception of direct audio transmitted by the sideward firing speaker (108) to provide optimum reproduction of the reflected sound. The virtual direct filter may be incorporated as part of a crossover circuit that separates the full band and sends high frequency sound to the sideward-firing driver (108).

  • Patent number: 9349378
    Abstract: Techniques for synthesizing a parameterized haptic track from a multichannel audio signal and embedding the haptic track in a multichannel audio codec bit stream. The haptic track synthesis can occur while encoding the multichannel audio signal as the multichannel audio codec bit stream. The haptic track can be synthesized in a way that allows select parameters of the haptic track to be extracted from the audio signal. The parameters can be adjusted by a user during the encoding process. For example, the parameter adjustments can be made using a authoring/monitoring tool. The parameter adjustments can be recorded as metadata that, along with the haptic track, is included in the codec bit stream. In some aspects the present technology, the adjustable parameters include center frequency, gain, decay rate, and other parameters that allow for modulation of the haptic track during decoding of the codec bit stream.

  • Patent number: 9324337
    Abstract: A method and system for enhancing dialog determined by an audio input signal. In some embodiments the input signal is a stereo signal, and the system includes an analysis subsystem configured to analyze the stereo signal to generate filter control values, and a filtering subsystem including upmixing circuitry configured to upmix the input signal to generate a speech channel and non-speech channels and a peaking filter configured to filter the speech channel to enhance dialog while being steered by at least one of the control values. The filtering subsystem also includes ducking circuitry for attenuating the non-speech channels while being steered by at least some of the control values, and downmixing circuitry configured to combine outputs of the peaking filter and ducking circuitry to generate a filtered stereo output.
