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, wherein the volume setting is associated with a target net volume for the corresponding listening zone;
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, based on the volume setting corresponding to each of the plurality of listening zones, estimated contributions to the target net volume for the given listening zone of outputs generated in each of the plurality of listening zones, 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, the output of the acoustic transducer being substantially in accordance with the target net volume for the corresponding listening zone.

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.
