Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a discriminating device for a plurality of sound sources that can specify respective sound sources such as an acoustic musical instrument, a natural sound, a human, and a living creature when the plurality sound sources generate sounds simultaneously, and an information processing device interlocking with the plurality of sound sources.SOLUTION: After sounds generated by the plurality of sound sources are recorded and acquired in the form of a digital acoustic signal (S210), frequency analysis of the acoustic signal is performed to generate feature data based upon a temporally averaged spectrum (S220), correlation calculation on the generated feature data and registered feature data registered in a sound source database is carried out to specify a sound source corresponding to registered feature data having a maximum correlation value (S230). When the sound source is successfully specified (S240), the feature data is corrected using the registered feature data corresponding to the specified sound source (S250), and processing for specifying a sound source is performed again (S230).
