摘要

PROBLEM TO BE SOLVED: To simply retrieve, e.g. the speech part of a specified speaker and the performance part of a specified musical instrument even without inputting a mark, etc., when recording is performed. SOLUTION: This method compares one to a plurality of retrieval key audio characteristic parameters depending on the structural elements of sound sources about one to a plurality of the sound sources being retrieval keys with the audio characteristic parameter obtained by analyzing the audio signal of a retrieval object, calculates the similarity between both of them and retrieves a part that is similar to an audio signal from the sound source for a retrieval key in the audio signal of the retrieval object.
