MULTI-ZONE AUDIO SYSTEM WITH INTEGRATED CROSS-ZONE AND ZONE-SPECIFIC TUNING
First Claim
1. A method comprising:
- receiving information indicative of a volume setting corresponding to each listening zone of a plurality of listening zones associated with a multi-zone audio system;
generating, by one or more processing devices, 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, andwherein the zone-specific adjustment signal is configured to adjust an output of corresponding zone-specific circuitry;
generating, by the one or more processing devices, an additional adjustment signal configured to adjust an output of a cross-zone equalization filter, wherein the output of the cross-zone equalization filter is configured to generate a target acoustic distribution across multiple listening zones, and wherein each of (i) the zone-specific adjustment signals and (ii) the additional adjustment signal is configured to adjust corresponding audio signals from a same audio source; and
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.

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. 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.
