Abstract
A highlight portion is detected to a high accuracy from acoustic signals in say an event, and an index is added to the highlight portion. In an acoustic signal processing apparatus, a candidate domain extraction unitretains a domain, a length of which with short-term amplitudes as calculated by an amplitude calculating unitnot being less than an amplitude threshold value is not less than a time threshold value, as a candidate domain. A feature extraction unitextracts sound quality featuring quantities, relevant to the sound quality, from the acoustic signals, to quantify the sound quality peculiar to a climax. A candidate domain evaluating unitcalculates a score value, indicating the degree of the climax, using featuring quantities relevant to the amplitude or the sound quality for each candidate domain, in order to detect a true highlight domain, based on the so calculated score value. An index generating unitgenerates and outputs an index including the start and end positions and the score values of the highlight domain.
