摘要： The present invention implements a method and an apparatus for retrieving a sound data desired by the user on the basis of its subjective impression over the sound data. The subjective impression on the desired sound data is entered by the user and converted to a numerical value. A target sound impression value which is a numerical form of the impression on the sound data is calculated from the numerical value. The target sound impression value is then used as a retrieving key for accessing a sound database where the audio signal and the sound features of a plurality of the sound data are stored. This allows the desired sound data to be retrieved on the basis of the subjective impression of the user on the sound data.

摘要： A sound features extracting unit receives a sound signal of a music piece to extract sound features. A peak detecting unit detects a peak time when a cost function calculated by a cost function calculating unit indicates a maximal value, and a peak value thereof. A selecting unit selects a time property indicating sound critical points from the peak time and the peak value. This method allows the user to automatically retrieve sound critical points without having to listen to the sound in advance.
