  • Patent number: 10531195
    Abstract: The technology described in this document can be embodied in a method that includes receiving information indicative of a volume setting corresponding to each listening zone of a plurality of listening zones. The method also includes generating a zone-specific adjustment signal for each of the plurality of listening zones, wherein the zone-specific adjustment signal for a given listening zone accounts for a cross-zone effect associated with a volume setting corresponding to another listening zone, and is configured to adjust an output of corresponding zone-specific circuitry. The method further includes generating an additional adjustment signal configured to adjust an output of a cross-zone equalization filter. The output of the cross-zone equalization filter is configured to generate a target acoustic distribution across multiple listening zones.

  • Publication number: 20190387345
    Abstract: In some implementation, a method includes: receiving at least one user interface command to modify a phantom center image of audio output from the audio system in the automobile, wherein the user interface command comprises a user profile command or a preset command attributed to a user of the automobile, wherein the user profile command or the preset command is obtained from an identification file attributed to the user, wherein the phantom center image of the audio output comprises a designated position of sound produced by a set of speakers in the audio system other than physical locations of the set of speakers in the audio system; and adjusting a perceived location of the phantom center image of the audio output from the audio system based upon the at least one user interface command to modify the phantom center image of the audio output.

  • Patent number: 10313819
    Abstract: Various implementations include computer-implemented methods and related systems for controlling the phantom center image of an audio output in an automobile. In one implementation, a method includes: receiving at least one user interface command to modify a phantom center image of audio output from the audio system in the automobile, wherein the phantom center image of the audio output includes a designated position of sound produced by a set of speakers in the audio system other than physical locations of the set of speakers in the audio system; and adjusting a perceived location of the phantom center image of the audio output from the audio system based upon the at least one user interface command to modify the phantom center image of the audio output.

  • Patent number: 10257613
    Abstract: A signal input module receives at least one of an entertainment audio signal and a telephony audio signal from vehicle sound circuitry. A level control module executes gain level control logic to balance the entertainment audio signal and a telephony audio signal according to a ratio. A gain control signal is applied to at least one of the entertainment audio signal and the telephony audio signal. A routing module mixes the entertainment audio signal and the telephony audio signal and routes the mixed signal to an output channel associated with a speaker.

  • Patent number: 10056068
    Abstract: An audio system includes a plurality of near-field speakers arranged in a listening area. A plurality of cross-talk cancellation filters are coupled to the speakers. The speakers and the filters are arranged to provide first and second listening zones in the listening area such that audio from the first listening zone is cancelled in the second listening zone and vice versa. The system also includes at least one audio source providing audio content. Volume-based equalization circuitry receives an audio signal representing audio content for the first listening zone from the audio source and controls a volume adjustment applied to the audio signal to control a volume of audio in the first listening zone. The circuitry limits attenuation or amplification of a first frequency portion of the audio signal when a volume setting differential corresponding to a difference between volume settings for the first and second zones exceeds a predetermined value.

  • Patent number: 8355512
    Abstract: A method for determining leakage factors or adaptation rates, or both, for adaptive filters in an active noise reduction system. The leakage factor or adaptation rate, or both, may vary depending on a parameter of an input reference signal. The parameter may include one or more of reference signal input frequency, rate of change of reference input signal frequency, if a predetermined triggering condition exits, or if a predetermined event has occurred.

  • Patent number: 8204242
    Abstract: An active noise reduction system using adaptive filters. A method of operation the active noise reduction system includes smoothing a stream of leakage factors. The frequency of a noise reduction signal may be related to the engine speed of an engine associated with the system within which the active noise reduction system is operated. The engine speed signal may be a high latency signal and may be obtained by the active noise reduction system over audio entertainment circuitry.
