Abstract: In a processing control unit 119, a correction measurement unit measures an aspect of sound field correction processing executed upon an acoustic signal UAS received from a sound source device 9200, that is a particular external device. And if an acoustic signal NAS or an acoustic signal NAD other than the acoustic signal UAS is selected as an acoustic signal to be supplied to speaker units 910L, through 910SR, then a sound field correction unit 113 generates an acoustic signal APD by executing sound field correction processing for the aforementioned measured aspect upon the selected acoustic signal. Due to this, whichever of the plurality of acoustic signals UAS, NAS, and NAD is selected, it is possible to supply that signal to the speaker units 910L, through 910SR in a state in which uniform sound field correction processing has been executed thereupon.

Abstract: A corrective measurement part of a processing control part 119A measures an aspect of specific sound field correction processing performed on an acoustic signal received from a specific external device. Based on this measurement result, settings for cancellation of specific sound field correction processing performed on that acoustic signal are made for a correction cancellation part 310. Furthermore, an aspect of appropriate sound field processing corresponding to the actual sound field space is acquired by an appropriate correction acquisition part of the processing control part 119A. Based on the result acquired in this manner, settings for performing appropriate sound field correction processing upon a signal SND are made for a correction processing part 330. Thus, whichever one of acoustic signals received by a reception processing part 111 is selected, an output acoustic signal can be supplied to speaker units in after appropriate sound field correction processing.
