    Abstract: An automobile audio system having at least two near-field speakers located close to an intended position of a listener's head is configured by determining a first binaural filter that causes sound produced by each of the near-field speakers to have characteristics at the intended position of the listener's head of sound produced by a sound source located at a first designated position other than the actual locations of the near-field speakers, determining an up-mixing rule to generate at least three component channel signals from an input audio signal having at least two channels, and configuring the audio system to, determine a first binaural signal corresponding to a combination of the component channel signals originating at the first designated position, and filter the first binaural signal using the first binaural filter and to output the filtered signals using the near-field speakers.

    Abstract: A system for providing augmented audio to users in a vehicle, comprising: a plurality of speakers disposed in a perimeter of a cabin of the vehicle; and a controller configured to receive a first audio signal and a second audio signal, to drive the plurality of speakers in accordance with a first array configuration such that a bass content of the first audio signal is produced in a first listening zone within the vehicle cabin, and to drive the plurality of speakers in accordance with a second array configuration such that a bass content of the second audio signal is produced in a first listening zone within the vehicle cabin, wherein in the first listening zone a magnitude of the first bass content is greater than a magnitude of the second bass content and in the second listening zone the magnitude of the second bass content is greater than the magnitude of the first bass content.

    Abstract: A system is provided for limiting distortion of an audio speaker. The system includes a first lowpass filter circuitry that is configured to receive a system input signal and generate a first lowpass filtered output signal. The system also includes a first limiter circuitry that is configured to limit the first lowpass filtered output signal. Limiting the first low pass filtered output signal includes reducing an amplitude of the first lowpass filtered output signal below a first predetermined threshold value, thereby to generate a first limited output signal. A second lowpass filter circuitry is configured to receive the first limited output signal and to generate a second lowpass filtered output signal.

    Abstract: The technology described in this document can be embodied in a system that includes a seat headrest enclosing at least one first acoustic transducer that generates audio output in a first frequency range. The system also includes an adjustable headrest wing disposed in front of the seat headrest, the headrest wing being pivotally coupled to the seat headrest and adjustable to one of multiple positions. The headrest wing includes at least one second acoustic transducer that generates audio output in a second frequency range that includes frequencies higher than the upper end of the first frequency range. The system further includes a controller configured to adjust, for a given position of the headrest wing, one or more parameters of at least one of: (i) the first acoustic transducer and (ii) the second acoustic transducer in accordance with a target acoustic distribution.
