Abstract:
A sound characteristic parameter is obtained for an audio signal to be analyzed by analyzing the signal by means of a sound characteristic parameter analyzing section arranged upstream relative to a similarity determining section. A sound signal operation as retrieving key is read out from a retrieving key storage area of a retrieving key memory by a retrieving key audio signal reading section and analyzed by a retrieving key sound characteristic parameter analyzing section to obtain a retrieving key sound characteristic parameter. The similarity determining section compares the sound characteristic parameter obtained from said sound characteristic parameter analyzing section and the retrieving key sound characteristic parameter obtained from said retrieving key sound parameter reading section and determines the similarity of them to retrieve a part of the audio signal to be analyzed that resembles the audio signal operating as retrieving key and obtained from the sound source of the retrieving key.
