<p>[Object] To provide an audio signal processing device whereby, from two systems of audio signals in which audio signals of multiple audio sources are included, the audio signals of the multiple audio sources can be suitably separated. [Solving Means] The audio signal processing device comprises dividing means 101 and 102 for dividing each of two systems of audio signals into a plurality of frequency bands, level comparison means 103 for calculating a level ratio or a level difference of the two systems of audio signals, at each of the divided plurality of frequency bands, and three or more output control means for extracting and outputting frequency band components of and nearby values regarding which the level ratio or the level difference calculated at the level comparison means have been determined beforehand. The frequency band components extracted and output by the three or more output control means are frequency band components with the level ratio or level difference at and nearby the values determined beforehand which are different one from another.</p> |
