  • Patent number: 9806795
    Abstract: Many types of earpiece include a memory to which media items stored on a second device, such as music, audiobooks, and podcasts, may be transferred as requested by a user. However, it may be advantageous to configure the earpiece and/or the to fill the memory automatically with media items of predicted interest to the user in the manner of a cache. In such earpieces, interruption of the connection between the earpiece and the second device does not interrupt a currently streaming media item, and the earpiece is capable of playing additional media items of predicted interest to the user even if the user has not requested transfer to the earpiece. Other uses of the cache include adding appointments from a calendar of the second device for presentation by the earpiece as reminders during disconnection, and storing notes on the earpiece that are automatically transferred back to the second device.

    Abstract: A mobile device detects use of a headset accessory and, in response, scans for wireless local area network (WLAN) access points that provide a public announcement service. The mobile device will connect with a WLAN access point and proceed to receive public announcement audio which is sent over the headset accessory. Any other audio being played over the headset will either be paused, or reduced in volume while the public announcement audio is played. Alternatively, if no WLAN access point is available, the mobile device can locate a low energy wireless protocol device, and receive public announcements via text message. The WLAN access point and low energy wireless protocol connections are disconnected if the headset accessory is disconnected or no longer in use.

  • Patent number: 9712938
    Abstract: The invention discloses rendering sound field signals, such as Higher-Order Ambisonics (HOA), for arbitrary loudspeaker setups, where the rendering results in highly improved localization properties and is energy preserving. This is obtained by a new type of decode matrix for sound field data, and a new way to obtain the decode matrix. In a method for rendering an audio sound field representation for arbitrary spatial loudspeaker setups, the decode matrix for the rendering to a given arrangement of target loudspeakers is obtained by steps of obtaining a number of target speakers, their positions, positions of a spherical modeling grid and a HOA order, generating a mix matrix from the positions of the modeling grid and the positions of the speakers, generating a mode matrix from the positions of the spherical modeling grid and the HOA order, calculating a first decode matrix from the mix matrix and the mode matrix, and smoothing and scaling the first decode matrix with smoothing and scaling coefficients.

  • Patent number: 9696884
    Abstract: An approach is provided for mixing at least one additional element on top of a media stream. A mix media platform determines at least a first media item for rendering in a first application. The mix media platform next determines one or more interactions with at least one connecting user interface element to associate a first representation of the first media item with a second representation of one or more media sources of a second application. The mix media platform then causes, at least in part, a mixing of the first media item and at least a portion of one or more second media items associated with the one or more media sources to cause, at least in part, a generation of a mix item.

  • Patent number: 9693160
    Abstract: The present invention relates to an audio processing system (100) for providing safe audio playback. An audio controller (110) outputs an intermediate audio signal (M) having a predefined test segment comprising a predefined test frequency component. An audio synthesis stage (120) provides, based on the intermediate audio signal, an output audio signal (P) for use in audio playback. An audio test is performed based on a first segment of the output audio signal corresponding to the test segment of the intermediate audio signal, and a safety processor (150) declares correct the operation of the audio synthesis stage in case the result of the audio test is positive. The safety processor declares correct the operation of a frequency monitor (130) if both the frequency monitor and a frequency-selective audio sensor (140) detect the test frequency in the first segment of the output audio signal.

  • Patent number: 9693162
    Abstract: A system, an audio output device, and a method for automatically adjusting a firing direction of an upward firing speaker are disclosed. The system includes the audio output device and an audio receiver. The audio output device includes the upward firing speaker. During testing, the device controls the speaker to output a test audio signal at each of multiple testing angles of elevation. The audio receiver within a receiving area receives the test audio signal and generates a received audio waveform for creating reception information. The audio output device selects one testing angle as a preset angle of elevation according to the reception information. At playing, the audio output device is controlled by a mode selection signal and chooses a correction value from a mode lookup table to adjust the preset angle. The speaker is controlled to output an audio signal at the adjusted preset angle.

  • Patent number: 9685927
    Abstract: A method of adjusting an audio signal equalizer setting. A first and a second equalizer setting are selected from a population of equalizer settings for undergoing a binary comparing decision. The two equalizer settings are presented to a user by consecutively replaying an audio signal filtered by an equalizing unit according to the first or to the second equalizer setting respectively. The user's binary comparing decision between the first and the second equalizer setting according to his preferences is acquired. Further binary comparing decisions are performed until all members of the settings population have been part of a binary comparing decision. A score for the each presented equalizer settings is adapted based on the user's binary comparing decisions results. A weighted averaging is performed, based on the scores, in the frequency domain between the equalizer settings that received a high score, to obtain the result of the equalizer adjustment method.

  • Patent number: 9672213
    Abstract: Embodiments are described for providing media items from a playback history for media items played by one or more playback zones in a media playback system. A computing device maintains the playback history. The playback history includes, for each of the media items, (i) an indication of a playback zone in which the media item was played, (ii) a time at which the media item was played, and (iii) metadata associated with the media item. The metadata may include, among others, at least one of an album associated with the media item, a genre associated with the media item, and a track name associated with the media item. The computing device, in response to a request, may transmit a portion of the playback history based on the request.
