  • Patent number: 10313803
    Abstract: A method suppresses feedback in a hearing instrument. A microphone generates an input signal and a loudspeaker generates an acoustic signal which is partially fed back to the microphone via an acoustic feedback path. An intermediate signal is generated along a main signal path depending on the input signal, and an output signal is formed on the basis of the intermediate signal. A voice activity of a user is monitored, a transfer function of an electro-acoustic closed signal loop formed by the main signal path and the feedback path is estimated, that, depending on the transfer function of the closed signal loop and the voice activity of the user, the intermediate signal is decorrelated to form the output signal. A compensation signal is generated from the output signal and is fed to the input signal for feedback compensation, and the output signal is fed to the loudspeaker for reproduction.

  • 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.

  • Patent number: 10251016
    Abstract: Systems, devices, and methods are described herein for adjusting a relationship between dialog and non-dialog signals in an audio program. In an example, information about a long-term dialog balance for an audio program can be received. The long-term loudness dialog balance can indicate a dialog-to-non-dialog loudness relationship of the audio program. A dialog loudness preference can be received, such as from a user, from a database, or from another source. A desired long-term gain or attenuation can be determined according to a difference between the received long-term dialog balance for the audio program and the received dialog balance preference. The long-term gain or attenuation can be applied to at least one of the dialog signal and the non-dialog signal of the audio program to render an audio program that is enhanced according to the loudness preference.

  • Patent number: 10242684
    Abstract: Systems and methods for adjusting audio levels in a plurality of audio signals are disclosed. One or more input signals containing one or more audio signals are depacketized. The audio signals are analyzed to determine if audio levels of the signals correspond to a desired audio level for at least some of the signals. The audio levels of signals that do not correspond are adjusted. Packets that do not require adjustment and the resulting adjusted packets are combined to form one or more output signals corresponding to the one or more input signals.

  • Patent number: 10209948
    Abstract: An input at a physical interface of a first playback device is detected. The input may indicate a playback command. Via the first playback device, the second playback device is determined to be currently playing media content. Based on determining that the second playback device is currently playing media content and based on receiving the input at the physical interface, the first playback device is caused to play the media content synchronously with the second playback device.

  • Patent number: 10109288
    Abstract: An audio encoding device is described herein. The audio encoding device includes a compressor that is based on a nonlinear filter. In particular, the nonlinear filter may be selected from the class of edge-preserving smoothing filters, which avoids common artifacts of conventional compressors. Edge-preserving smoothing filters have been used in image processing algorithms for their de-noising properties while preserving edges in the image. These properties are useful for audio compression because macro-dynamic loudness changes can be tracked precisely while micro-dynamic loudness changes can be ignored for the compression. Due to these advantages, more aggressive compression can be achieved with less distortion.

  • Patent number: 10079871
    Abstract: A user device receives a first media item that is associated with a second media item. The device determines that a playback state for the device indicates that the device is paired with an alternative playback device. The device sends the playback state in a request for the second media item, receives the second media item in a first format for playback on the user device and in a second format for playback on the alternative playback device. The device determines whether the playback state of the device is the same. The device displays a first graphical representation of the second media item in the first format on the user device if the user device is no longer paired with the alternative playback device and displays a second graphical representation of the second media item in the second format on the user device if the user device is still paired with the alternative playback device.
