摘要： An entertainment audio processing system includes a music limiter configured to receive an audio signal, volume control information for music, and volume control information for announcement. The music limiter is further configured to calculate a gain parameter based on a music-to-announcement ratio. In another aspect, an entertainment audio processing system includes a mixer configured to substantially match a left audio signal channel and a right audio signal channel. The entertainment audio processing system further includes an equalizer configured to introduce magnitude and phase changes between the left audio signal channel and the right audio signal channel.

摘要： An automobile audio system includes a signal processor configured to receive and process audio signals from a source and provide processed audio signals to an amplifier, a first headrest including a headrest speaker and coupled to a driver's seat, a first fixed speaker positioned near a left corner of the vehicle's cabin forward of the headrest, a second fixed speaker positioned near a right corner of the vehicle's cabin forward of the headrest, and a headrest accessory port located in a passenger's seat. The port is configured to connect the audio system to a second headrest speaker. The processor uses a first set of parameters for processing the received audio signals when the first headrest speaker is connected and the second headrest speaker is not connected, and a second set of parameters for processing the received audio signals when both the first and second headrest speaker are connected.

摘要： 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. The method also includes generating an output of an acoustic transducer of the multi-zone audio system based on the zone-specific adjustment signals and the additional adjustment signal.

摘要： Among other things, one or more non-transitory machine-readable media storing instructions are described. The stored instructions are executable by one or more processing devices to perform operations comprising analyzing an effect of noise in a spatial unit on sound in the spatial unit, at least part of the sound being produced by audio signals; selecting an adjustment curve among a group of adjustment curves based on one or more characteristics of the noise; and determining an amount of adjustment to be made to the audio signals based on the analyzed effect and the selected adjustment curve.

摘要： 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.

摘要： Signals in an automobile audio system having at least two near-field speakers located close to an intended position of a listener's head are adjusted such that in a first mode, audio signals are distributed to the near-field speakers according to a first filter that causes the listener to perceive a wide soundstage, and in a second mode, the audio signals are distributed to the near-field speakers according to a second filter that causes the listener to perceive a narrow soundstage. A user input of a variable value is received and, in response, distribution of the audio signals is transitioned from the first mode to the second mode, the extent of the transition being variable based on the value of the user input.

摘要： 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.
