摘要： 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. Volume-based equalization circuitry receives an audio signal representing audio content for the first listening zone from an 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.

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, the second lowpass filter circuitry reducing distortion. Another aspect provides a method for limiting distortion of a loudspeaker by a multi-band limiter wherein the input signal is split into frequency bands and individually limited. Additionally, an all-pass filter circuitry correcting the phase in the highpass branch and a master limiter may be provided.

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.
