[Problem] To generate acoustic profile information using a simple operation and without increasing the cost of a multichannel audio device. [Solution] A wireless recording playback terminal 5 is positioned at a listening point of a multichannel audio device 2 as a measuring microphone. The wireless recording playback terminal 5 records, as channel playback data in accordance with a test signal playback command received from the multichannel audio device 2, a test signal outputted from a speaker 3 that corresponds to the channel designated by the command. The wireless recording playback terminal 5 also plays back the sound source of the test signal and records the played-back sound source as sound source playback data without being outputted to the outside from the speaker. An acoustic profile information generation server 4 compares these playback data to measure the delay time and attenuation rate of the channel playback data with respect to the sound source playback data, generates the acoustic profile information of the designated channel on the basis of the result of this measurement, and sets the generated acoustic profile information to the multichannel audio device 2.
