Abstract:
1. An audio signal processing system comprising: a plurality of audio signal processing devices each processing an audio signal; a controller controlling operations of said respective audio signal processing devices; and a network which connects each of said plurality of audio signal processing devices and said controller, wherein each of said plurality of audio signal processing devices functions as one processing block that executes audio signal processing and any combination of one or more audio signal processing devices among said plurality of audio signal processing devices cooperatively execute an audio signal processing under control of said controller, wherein said controller comprises: a memory that stores, as each of a plurality of zone data, specifying data, a plurality of configuration data, and one or more scene data, the specifying data specifying one or more audio signal processing devices which cooperatively execute the audio signal processing out of said plurality of audio signal processing devices, each of the plurality of configuration data indicating, for each of said one or more specified audio signal processing devices, components and wires between the components corresponding to a configuration of signal processing to be executed by said specified audio signal processing device as the processing block, and each of the scene data indicating an audio signal processing which corresponds to each of the one or more specified audio signal processing devices; a selecting device that selects the zone data; a checking device that checks, in response to selection of the zone data by said selecting device, that said one or more audio signal processing devices specified by the specifying data in the selected zone data are prepared for audio signal processing as a processing block in the cooperative audio signal processing based on the selected zone data; a transferring device that transfers, to each of said one or more audio signal processing devices that are confirmed as prepared by said checking device, portions of configuration data corresponding to the audio signal processing device among the configuration data included in the selected zone data; an accepting device that accepts, in a state where transmission of the configuration data has been completed regarding one zone data, selection of the scene data included in the selected zone data; and an instructing device that, in response to the acceptance of the selection of the scene data by said accepting device, instructs said one or more audio signal processing devices specified by the specifying data included in the zone data in which the selected scene data is included, to execute the audio signal processing corresponding to the selected scene data, and wherein each of said audio signal processing devices comprises: a memory that stores the portions of the configuration data transferred from said controller; and a processor that, in response to the instruction by said controller to execute the audio signal processing corresponding to a given scene data, executes the audio signal processing configured of the components and the wires between the components indicated by the configuration data corresponding to the given scene data.
