摘要

PROBLEM TO BE SOLVED: To make efficiently searchable the acoustic data without completely decoding the acoustic data at the time of searching the acoustic data compressed for coding by recording the detected spectrum characteristic information and the waveform characteristic information in a detected time area with the information for showing the relation to the input acoustic data. SOLUTION: A data shaping unit 15 generates a descriptor, in which various characteristic and attributed information of the acoustic data are written, on the basis of the spectrum characteristic information from a spectrum characteristic detecting unit 12 and the waveform characteristic information in a time area from a waveform characteristic detecting unit 13. The data reshaping unit 15 includes the discrimination information as the information for showing the relation between the acoustic data and the descriptor in the descriptor, and adds the corresponding discrimination information to the acoustic data. With this structure, even if the acoustic data and the descriptor are separately recorded, they can be searched for checking each other.
