  • Publication number: 20240381045
    Abstract: A system configured to create a flexible home theater group using a variety of different devices. To enable the home theater group to generate synchronized audio, the system performs device localization to generate map data, which represents locations of devices in a device map. The map data may include a listening position and/or television, such that the map data is centered on the listening position with the television along a vertical axis. To generate the map data, the system selects a primary device that determines calibration data indicating a sequence when each of the individual devices generates playback audio. The primary device sends the calibration data to secondary devices and each device generates playback audio at a designated time in the sequence, enabling other devices to capture the output audio and determine a relative position of the playback device (for example using angle of arrival and distance information). The playback audio may be outside a human hearing range.

  • Publication number: 20240342591
    Abstract: Methods and systems are provided for independent audio volume control. An example audio system may include a hearing device operable to adaptively control a first signal, according to a setting, to provide an audio output. The hearing device may be operable to generate a new value of the setting according to an input that is received at a particular time, and adjust the setting from an old value to the new value according to a delay with respect to the particular time. The adaptive controlling may include one or both of mixing of the first signal with a second signal and applying a volume adjustment of the audio output according to the setting. The second signal may include audio generated via a game console and/or via a smartphone.

  • Patent number: 12114134
    Abstract: An enhancement equalizer (EEQ) can be configured to compensate for hearing loss. An app or application can assist a user with measuring hearing loss at various frequencies (e.g., threshold sensitivity versus normal hearing). Using these measurements, the system may compute a set of filters for an EEQ that can boost different frequencies by different amounts corresponding to the user's sensitivity to that frequency. The measurement and resulting EEQ may be earphone specific (e.g., both the measurement and the filter computation may depend on the particular type/model of earphone used). In some implementations, the system may allow the user to select correction strength that controls an amount of correction applied (e.g., 25%, 50%, or 75% of full correction). In some implementations, the system may adjust the EEQ and/or correction strength according to the volume of playback (e.g., by applying less correction at higher playback volumes to avoid triggering earphone limiters).

  • Publication number: 20240299843
    Abstract: In an audio device that includes a plurality of input controls, mixing circuitry, a left speaker, and a right speaker, a desired balance, between a first audio signal and a second audio signal, may be determined according to the plurality of input controls. A desired volume, of the first audio signal and the second audio signal, may be determined according to the plurality of input controls. A virtualization, of one or both of the first audio signal and the second audio signal, may be determined according to a head related transfer function. A stereo signal may be generated by combining the first audio signal and the second audio signal according to the desired balance, the desired volume, and the virtualization. A left channel of the stereo signal may be outputted to the left speaker and a right channel of the stereo signal may be outputted to the right speaker.

    Abstract: A system comprising audio processing circuitry is provided. The audio processing circuitry is operable to receive audio signals. The audio processing circuitry is operable to process the audio signals to detect strength of a chat component of the audio signals and strength of a game component of the audio signals. The audio processing circuitry is operable to automatically control a volume setting based on one or both of: the detected strength of the chat component, and the detected strength of the game component. The combined-game-and-chat audio signals may comprise a left channel signal and a right channel signal. The processing of the combined-game-and-chat audio signals may comprise measuring strength of a vocal-band signal component that is common to the left channel signal and the right channel signal.
