Abstract:
1. An audio signal processing system comprising a plurality of audio signal processing apparatuses that process audio signals according to specified signal processing configurations and according to specified parameters used in processing of the audio signals, the plurality of the audio signal processing apparatuses being connected to each other through a network, wherein the plurality of the audio signal processing apparatuses are previously linked to form a zone, and are defined as devices belonging to the zone and further the devices are grouped into a plurality of device groups within the zone, wherein each of the plurality of the audio signal processing apparatuses includes: a device group table that registers information specifying controls which are performed in respective audio signal processing apparatuses belonging to a device group in case that a group control command is given for collectively controlling the device group; and a master table that registers information specifying controls which are performed in respective device groups included in the zone in case that a zone control command is given for collectively controlling the zone, and wherein the audio signal processing apparatus belonging to the device group comprises: a receiving section that receives a control command issued by a user manipulation or a control command inputted from an external device through the network; a determining section that determines whether the received control command is a group control command or a zone control command; a first transmitting section operative when the received control command is the group control command for transmitting an individual control command corresponding to the received group control command to each of the audio signal processing apparatuses belonging to the device group, with reference to the device group table; and a second transmitting section operative when the received control command is the zone control command for transmitting an individual group control command according to the received zone control command to each of the device groups included in the zone, with reference to the master table, wherein the device group table includes a device group scene table that registers one or more of scenes, each scene specifying parameters set to the audio signal processing apparatuses belonging to the device group, wherein the master table includes a scene master table that registers one or more of scene links, each scene link specifying a plurality of scenes in correspondence to the plurality of the device groups belonging to the zone, wherein the group control command is effective to select one of the scenes from the device group scene table so that the parameters specified by the selected scene are collectively set to the audio signal processing apparatuses belonging to the same device group, and wherein the zone control command is effective to select one of the scene links from the scene master table so that the parameters specified by the scenes specified by the selected scene link are collectively set to the audio signal processing apparatuses belonging to the same zone.
