  • Patent number: 10311882
    Abstract: The present invention relates to a new method and apparatus for improvement of High Frequency Reconstruction (HFR) techniques using frequency translation or folding or a combination thereof. The proposed invention is applicable to audio source coding systems, and offers significantly reduced computational complexity. This is accomplished by means of frequency translation or folding in the subband domain, preferably integrated with spectral envelope adjustment in the same domain. The concept of dissonance guard-band filtering is further presented. The proposed invention offers a low-complexity, intermediate quality HFR method useful in speech and natural audio coding applications.

  • Patent number: 10303429
    Abstract: An example playback device may store an active volume state variable in memory, where the active volume state variable corresponds to a current playback volume. The playback device may also store a volume limit state variable in memory, where the volume limit state variable corresponds to a playback volume limit of the playback device. The playback device may detect a command to begin playback of media from a given source and then select a startup playback volume to be one of the current playback volume and the playback volume limit based on the given source of the command to begin playback. The playback device may then play back media at the startup playback volume.

  • Patent number: 10254824
    Abstract: An audio playback device may be capable of operating in a “shuffle” mode in which audio or other content items are randomly selected. Environmental factor(s) such as ambient conditions or forces applied to the device or a peripheral can be used to identify one or more subsets of available content items from which content items are selected to thereby provide an “ambient shuffle” mode. By including or excluding items from the subset, the randomly-selected content items may more likely match the conditions under which the playback device is operating and/or match input provided by a user via tapping on, shaking, or otherwise applying force to the device or components in communication with the device.

  • Patent number: 10256785
    Abstract: Distortion reducing multi-band compressor with timbre preservation is provided. Timbre preservation is achieved by determining a time-varying threshold in each of a plurality frequency bands as a function of a respective fixed threshold for the frequency band and, at least in part, an audio signal level and a fixed threshold outside such frequency band. If a particular frequency band receives significant gain reduction due to being above or approaching its fixed threshold, then a time-varying threshold of one or more other frequency bands are also decreased to receive some gain reduction. In a specific embodiment, time-varying thresholds can be computed from an average difference of the audio input signal in each frequency band and its respective fixed threshold.

  • Patent number: 10241742
    Abstract: Method and systems are provided for identification of device groups in a network. In an example implementation, a first playback device, while in a first zone group comprising the playback device, the first zone group having a group identification identifying the first zone group, receives an instruction to form a zone group with one or more second playback devices. In response, the first playback device forms a second zone group with the one or more second playback devices. Forming the second zone group involves determining a group identification identifying the second zone group and determining a display name representing the second zone group. In response, the first playback device causes a controller device to update a control interface for the media playback system to display an indication of the second zone group, the indication of the second zone group comprising the determined display name.

  • Patent number: 10231010
    Abstract: In an example implementation, a system groups a first playback device and a second playback device into first player group. The system associates the first player group with a first playback queue that includes items for playback by the first player group. The first and second playback devices are configured to play items from the first playback queue while in the first player group. The system associates a third playback device with a second playback queue that includes items for playback by the second playback device. Thereafter, the system groups the first, second and third playback devices to form a second player group such that each of the first, second, and third playback devices are configured to play items from the second playback queue. The system removes the first playback device from the second player group and automatically associates the first playback device with the first playback queue.
